Hydrogen can be prepared on a small scale by the hydrolysis of metal hydrides:
CaH2 + 2H20 — Ca(OH)2 + 2H2
Assign an oxidation number to each atom and verify that the total number of electrons lost is equal to the total number gained.
Answer:
Ca²⁺ + 2H⁻ + 2(2H⁺ + O²⁻) ----> Ca²⁺ + 2O²⁻ + 2H⁺ + 4H⁰
(2 electrons lost) ----> (2 electrons gained)
Explanation:
The equation of the reaction is as follows: CaH₂ + 2H₂0 —> Ca(OH)₂ + 2H₂
The oxidation numbers of each of the atoms in the molecules are as follows:
In CaH₂, calcium has an oxidation number of +2, while hydrogen has an oxidation number of -1 ; Ca²⁺, 2H⁻
In 2H₂0, hydrogen has an oxidation number of +1 while oxygen has an oxidation number of -2 ; H⁺, O²⁻
In Ca(OH)₂, calcium has an oxidation number of +2 while oxygen has an oxidation number of -2 and hydrogen has an oxidation number of +1 ; Ca²⁺, O²⁻, 2H⁺
In 2H₂, each hydrogen atom has an oxidation number of 0 ; 4 H⁰
Ca²⁺ + 2H⁻ + 2(2H⁺ + O²⁻) ----> Ca²⁺ + 2O²⁻ + 2H⁺ + 4H⁰
On the left hand side, the hydride ion gives up two electrons to become neutral hydrogen atoms.
On the right hand, two hydrogen atoms accept two electrons to form neutral atoms.
These neutral hydrogen atoms pair up to form two hydrogen gas molecules.

Select the conjugate acid-base pair(s). a) HI, I b) HCHO2, SO4^2- c) CO3^2-, HCI d) PO4^3-, HPO4^2-
Answer:
PO4^3-, HPO4^2-
Explanation:
If an acid gives out a proton, the acid then changes to its corresponding base. Similarly, if a base takes in a proton, it changes to its corresponding acid. If a pair of acid and base differ only by the presence or absence of a proton, then they are referred to as a conjugate acid-base pair.
Let us look at this;
HPO4^2-(aq) ----> H^+(aq) + PO4^3-(aq)
HPO4^2- and PO4^3- differ only in the presence or absence of a proton (H^+) hence they constitute a conjugate acid-base pair.

2. (2 points) Calculate the Effective Nuclear Charge for each atom. Show all of your work for full credit. Se: Br: (1 point) Which atom is larger? (This is your claim.)
Answer:
Bromine.
Explanation:
There is more nuclear charge on bromine because in bromine, there are 35 number of protons and 46 number of neutrons while in selenium, there are 34 number of protons and 45 number of neutrons. The atomic size of selenium is larger because they have lower nuclear charge as compared to bromine and we know that when we go to the left of periodic table atomic size increases which attract the electrons towards itself so the shell comes close to the nucleus and decrease occurs in atomic radius.

Arrange these reactions according to increasing ΔS.
a. H 2O(g) → H 2O(l)
b. 2NO(g) → N 2(g) + O 2(g)
C. MgCO 3(s) → MgO(s) + CO2(g)
Explanation:
ΔS denotes change in entropy. Entropy is the degree of disorderliness of a system. An increasing ΔS would mean that the entropy of the products is greater than the entropy of the reactants.
Generally the trend of entropy with state of matter is given as;
Gas > Liquid > Solid (Increasing Entropy)
a. H 2O(g) → H 2O(l)
In this reaction, there is a decreasing ΔS, since we are moving from gas to liquid. This would be the last.
b. 2NO(g) → N 2(g) + O 2(g)
There is an increase in gaseous products. This is definitely an increasing ΔS reaction. This would be the first on the list.
C. MgCO 3(s) → MgO(s) + CO2(g)
The products formed are in solid and gaseous state. There is increasing ΔS but not up to reaction 2.
The order is given as;
b. 2NO(g) → N 2(g) + O 2(g)
C. MgCO 3(s) → MgO(s) + CO2(g)
a. H 2O(g) → H 2O(l)
Phosphorus-32 has a half-life of 14.0 days Starting with 4.00 g of 2P how many grams will remain after 112 days?

In order to derive a simplified version of the Nernst equation by assuming standard temperature we can substitute which of the following into the general equation?
a. Faraday's constant
b. Standard pressure (1 atm)
c. 298 K
d. 25 °C
Answer:
c. 298 K
Explanation:
Nernst equation is an equation used in electrochemistry that relates the reduction potential of a reaction with the standard potential, temperature and concentrations of the reactants in that are been reducted and oxidized. The formula is:
E = E° - RT / nF ln [Red] / [Ox]
Where R is gas constant (8.314J/molK), T is absolute temperature (In Kelvin), n are moles of electrons and F is faraday constant (K/Volt*mol)
In electrochemistry, standard temperature is taken as 298K. That means by assuming standard temperature we can substitute T as:
c. 298 KVitamin C ascorbic acid (C6F1806), is a reducing agent. One way to determine the ascorbic acid content of a sample is to mix the acid with an excess of iodine
C6H8O6 + I2 + H2O------- C6H6O6 + 2H3O + 2I-
and then titrate the iodine that did not react with the ascorbic acid with sodium thiosulfate. The balanced, net ionic equation for the reaction occurring in this titration is
I2+ 2 S2O32-(a9) —) 2 I-(a9) + S4O62-(a9)
Suppose 50.00 mL of 0.0520 M 12 was added to the sample containing ascorbic acid. After the ascorbic acid/I2 reaction was complete, the 12 not used in this reaction required 20.30 mL of 0.196 M Na2S2O3 for titration to the equivalence point. Calculate the mass of ascorbic acid in the unknown sample.
Answer:
The mass of ascorbic acid in the sample is 0.1076g
Explanation:
In other words to determine ascorbic acid in a sample:
You are adding an amount of I₂. One part is reacting with ascorbic acid and the other with sodium thiosulphate. First, we need to calculate how much thiosulphate reacts to know the iodine that reacts with thiosulphate.
I₂ that reacts with S₂O₃²⁻:
Moles S₂O₃⁻: 0.02030L × (0.196mol / L) = 3.979x10⁻³ moles S₂O₃²⁻.
As 2 moles of S₂O₃²⁻ reacts per moles of I₂, moles of I₂ are:
3.979x10⁻³ moles S₂O₃²⁻ ₓ (1 mole I₂ / 2 moles S₂O₃²⁻) = 1.989x10⁻³ moles I₂
Now, initial amount of I₂ added to the sample is:
0.0500L ₓ (0.0520mol I₂ / L) = 2.600x10⁻³ moles I₂
That means moles of I₂ that react with ascorbic acid = Moles of ascorbic acid are:
2.600x10⁻³ moles I₂ - 1.989x10⁻³ moles I₂ =
6.11x10⁻⁴ moles I₂ = Moles C₆H₈O₆.
To convert moles of substance to mass we need to use molar mass of the substance (176.12g/mol for ascorbic acid):
6.11x10⁻⁴ moles C₆H₈O₆ ₓ (176.12g / mol) =
The mass of ascorbic acid in the sample is 0.1076gGlade air freshener gel “disappearing” is an example of
Answer:
Vaporization
Explanation:
Vaporization is the change of a specie to the gaseous state. To 'disappear' in this case simply means to change to the gaseous state.
Substances with high vapour pressure tend to be easily converted to vapour phase. Hence if Glade air freshener gel 'disappears' easily, then it has a high vapour pressure and is easily converted to vapour (gas).

How many grams of gold are there in 0.353 moles of gold?
Answer: Approximately 69.5 grams of gold (Au).
Explanation:
mol = mass / molar mass
We are already given the moles of gold, 0.353. Looking at a periodic table, we cna bserve that the approximate molar mass of gold is 196.97 (I got this from ptable.com).
Plugging this into the formula above, it will look like this:
0.353 mol Au = mass / (196.97 g/mol) (in any science class, do not forget about writing your units)
To get mass by itself, multiply both sides of the equation by 196.97 g/mol.
This yields that the mass is equal to 69.5 grams. As you can see, the units of "mol" cancel out: 0.353 mol AU * (196.97 g/mol)
The reason why I rounded my answer to 69.5 grams instead of, let's say, 69.5304, is because of a concept in science referred to as significant figures. In this case, the amount of significant figures we need to round our answer to is seen in the provided value in the problem. 0.353 has only three significant figures so I have rounded the final answer to three significant figures.
Remember, do not forget to not only unclude e units that answer should be in but some teachers also request that you write the symbol of the elemnt you are writing about, so I would write my answer as: 69.5 g Au.

Answer:
The reactants should be ethyl bromide and sodium methoxide.
The products of the reactions are diethylether and sodium bromide.
Explanation:
When ethyl bromide, it reacts with any sodium ethoxide, it gives diethylether and also sodium bromide.
As in the sodium ethoxide, the negatively charged oxygen atom is very much reactive and it attacks on the bromine containing a carbon of the ethyl bromide and it replaces it forming methyl ethoxide. This type of reaction is sometimes known as SN2.
Consider the reaction when aqueous solutions of potassium hydroxide and ammonium nitrate are combined. The net ionic equation for this reaction is:
Answer: [tex]OH^-(aq)+NH_4^+(aq)\rightarrow NH_3(g)+H_2O(l)[/tex]
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
[tex]KOH(aq)+NH_4NO_3(aq)\rightarrow KNO_3(aq)+NH_3(g)+H_2O(l)[/tex]
The equation can be written in terms of ions as:
[tex]K^+(aq)+OH^-(aq)+NH_4^+(aq)+NO_3^-(aq)\rightarrow K^+(aq)+NO_3^-(aq)+NH_3(g)+H_2O(l)[/tex]
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The ions which are present on both the sides of the equation are potassium and nitrate ions and hence are not involved in net ionic equation.
Hence, the net ionic equation is :
[tex]OH^-(aq)+NH_4^+(aq)\rightarrow NH_3(g)+H_2O(l)[/tex]

b. 8.1 x 10^−4
c. 1.6 x 10^−3
d. 2.0 x 10^−4
e. 4.1 x 10^−4
Answer:
e. 4.1 x 10^−4
Explanation:
For the reaction;
2N2O5(g) → 4NO2(g) + O2(g)
The rate of formation is given as;
(1 / 4) Δ [O2] / Δt = (1 / 2 )Δ [N2O5] / Δt
Δ [O2] / Δt = 8.1 x 10^−4 M/s
Inserting into he equation, we have;
(1/4) (8.1 x 10^−4 ) = (1/2) (Δ [N2O5] / Δt)
2.025 x 10^−4 = (1/2) (Δ [N2O5] / Δt)
Δ [N2O5] / Δt = 2 * 2.025 x 10^−4
Δ [N2O5] / Δt = 4.1 x 10^−4
Correct option is option E.

Now make an ICE chart
So it can be like
M₂X₃(s) ⇄ 2 M³⁺(aq) + 3 X²⁻(aq)
I 0 0
C +2S +3S
E 2S 3S
Now The solubility product constant is:
Ksp = [M³⁺]² × [X²⁻]³
