Answers

Answer:

La respuesta correcta es la opción A.

Explicación:

La densidad del corcho es 0.95g / cm3 por lo que se hundirá en la solución de acetona porque el corcho es más denso que la solución de acetona mientras que por otro lado, el corcho flotará en otros dos líquidos porque la densidad del corcho es menor que en otros dos líquidos o, en otras palabras, los dos líquidos son más densos que el corcho, por eso el corcho flotará en estos dos líquidos.

You've made a hot drink by dissolving a teaspoon of instant coffee and a teaspoon of sugar in a cup of hot water. Which of the following statements is true? Group of answer choices The water is the solute portion of the drink. The instant coffee and sugar dissolve because they have no charged regions to repel the partial positive and partial negative regions of the water molecules. The instant coffee and sugar are solvents. You've just prepared an aqueous solution.

Answers

Answer: The statement, you've just prepared an aqueous solution is true.

Explanation:

When one or more number of substances are dissolved in a solvent like water then solution formed is called an aqueous solution.

For example, when a hot drink is made by dissolving a teaspoon of instant coffee and a teaspoon of sugar in a cup of hot water is an aqueous solution.

Here, both coffee and sugar are solute whereas hot water is the solvent.

Thus, we can conclude that the statement, you've just prepared an aqueous solution is true.

A gas occupies 0.67 L at 350 K. What temperature is required to reduce
the volume to 0.21 L *

Answers

Answer:

109.7K

Explanation:

Using Charles law equation as follows;

V1/T1 = V2/T2

Where;

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

V1 = 0.67L

V2 = 0.21L

T1 = 350K

T2 = ?

Using the formula above;

0.67/350 = 0.21/T2

0.001914 = 0.21/T2

0.001914T2 = 0.21

T2 = 0.21/0.001914

T2 = 109.7K

Standardization of a Borax solution (Na2B4O7). You are given a 1.044 M solution of H2SO4. It takes 2.63 mL of this H2SO4 to reach the end point. Knowing it takes 1 H2SO4 to neutralize 2 Na2B4O7, what was the concentration of this Borax solution?

Answers

The question is incomplete, the complete question is:

Standardization of a Borax solution (Na2B4O7). A student titrates a 20.00 mL sample of an aqueous borax solution with 1.044 M H2SO4. It takes 2.63 mL of acid to reach the equivalence point. Knowing it takes 1 H2SO4 to neutralize 2 Na2B4O7, what was the concentration of this Borax solution?

Answer: The concentration of borax solution is 0.069 M.

Explanation:

To calculate the concentration of borax solution, the formula used is:

[tex]n_1C_1V_1=n_2C_2V_2[/tex] ....(1)

where,

[tex]n_1, C_1\text{ and }V_1[/tex] are the n-factor, concentration and volume of sulfuric acid

[tex]n_2,C_2\text{ and }V_2[/tex] are the n-factor, concentration and volume of borax solution.

We are given:

[tex]n_1=1\\C_1=1.044M\\V_1=2.63mL\\n_2=2\\C_2=?M\\V_2=20mL[/tex]

Putting values in equation 1, we get:

[tex]1\times 1.044\times 2.63=2\times C_2\times 20\\\\C_2=\frac{1\times 1.044\times 2.63}{2\times 20}\\\\C_2=0.069M[/tex]

Hence, the concentration of borax solution is 0.069 M.

Answers

Answer:

For 1: Ionic

For 2: Ions

For 3: Covalent

For 4: Single

For 5: Double

For 6: Polar

Explanation:

For 1:

An ionic compound is formed when the complete transfer of electrons takes place from one element usually, metals (forming cation) to another element usually, non-metals (forming anions).

Hence, an ionic bond forms when one atom gives up one or more electrons to another atom

For 2:

An ion is formed when an element loses or gains an electron. Two types of ions are formed which are cations and anions.

Hence, atoms or molecules with a net electric charge due to the loss or gain of one or more electrons are ions.

For 3:

A covalent bond is defined as the bond which is formed by the sharing of electrons between two atoms.

Hence, a covalent bond involves sharing electron pairs between atoms, also known as a molecular bond.

For 4:

A single bond is defined as the bond in which 1 bond is present between the two atoms or 1 pair of electrons (two electrons) are shared between the atoms.

Hence, when one pair of electrons is shared between two atoms, a single bond is formed.

For 5:

A double bond is defined as the bond in which 2 bonds are present between the two atoms or 2 pairs of electrons (four electrons) are shared between the atoms.

Hence, when two pairs of electrons are shared between two atoms, a double bond is formed

For 6:

A polar bond is defined as the bond where unequal sharing of electrons takes place. This creates a dipole within a molecule.

Hence, a polar bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

A boulder rests on a ledge 31.2 m above a lake. If it has 2.65 x 10 J of gravitational
potential energy relative to the lake surface, what is the mass of the boulder?

Answers

Answer:

This question is incomplete, the gravitational potential energy is 2.65 x 10^5 J

mass of the boulder = 866.7g

Explanation:

Potential energy (P.E) refers to the energy due to the position of a body. It can be calculated as follows:

P.E = m × g × h

Where;

m = mass of substance (g)

g = acceleration due to gravity (m/s²)

h = height (m)

According to the information provided in this question,

h = 31.2 m

g = 9.8m/s²

m = ?

P.E = 2.65 x 10^5 J

Using P.E = m × g × h

2.65 x 10^5 = m × 9.8 × 31.2

2.65 x 10^5 = 305.76m

265000 = 305.76m

m = 265000 ÷ 305.76

m = 866.69

mass of the boulder = 866.7g

The equation for the reaction is:
2 Au + 3 Cl2 - 2 AuCla
Calculate the mass of chlorine needed to react with 0.175 g of gold.
Give your answer in mg
Relative atomic masses (Ar): Cl = 35.5 Au = 197

Answers

Answer: The mass of chlorine gas required is 94.6 mg

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

Given mass of gold = 0.175 g

Molar mass of gold = 197 g/mol

Plugging values in equation 1:

[tex]\text{Moles of gold}=\frac{0.175g}{197g/mol}=0.000888 mol[/tex]

The given chemical equation follows:

[tex]2Au+3Cl_2\rightarrow 2AuCl_3[/tex]

By the stoichiometry of the reaction:

If 2 moles of gold reacts with 3 moles of chlorine gas

So, 0.000888 moles of gold will react with = of chlorine gas

Molar mass of chlorine gas = 71 g/mol

Plugging values in equation 1:

[tex]\text{Mass of chlorine gas}=(0.001332mol\times 71g/mol)=0.0946g=94.6mg[/tex]       (Conversion factor: 1 g = 1000 mg)

Hence, the mass of chlorine gas required is 94.6 mg

Calculate the number of O atoms in 0.364 g of CaSO4 · 2H2O

Answers

Answer:

= 7.66 x 10²¹  oxygen atoms in 0.364 grams of  CaSO₄·2H₂O

Explanation:

For problems like this posting, one needs an understanding of the following topics:

The definition of the mole

1 mole of substance = mass in grams of substance containing 1 Avogadro's Number ( = 6.023 x 10²³ ) of particles of the specified substance. This is generally one formula weight of the substance of interest. From this, the following equivalent relationships should be memorized:

  1 mole = 1 formula weight = 1 mole weight (g)= 6.023 x 10²³ particles

Converting grams to moles:

Given grams => moles = grams/gram formula wt

Converting moles to grams:

Given moles => grams = moles x gram formula wt

_________________________________________________________

Calculate the number of O atoms in 0.364 g of CaSO₄ · 2H₂O.

Given mass CaSO₄ · 2H₂O = 0.364 grams

Formula Wt CaSO₄ · 2H₂O = 172 g/mole

moles CaSO₄ · 2H₂O = mass CaSO4 · 2H2O / formula Wt. CaSO₄ · 2H₂O

= 0.364 g CaSO₄·2H₂O / 172 g CaSO4·2H2O

= (0.364/172) mole CaSO₄·2H₂O

= 2.12 x 10⁻³ mole CaSO₄·2H₂O    

∴ number of Oxy (O) atoms in 0.364 grams CaSO₄·2H₂O

=  (2.12 x 10⁻³ mole CaSO₄ · 2H₂O)(6.023 x 10²³ molecules CaSO₄· 2H₂O/ mole)

= 1.276876 x 10²¹molecules CaSO₄· 2H₂O  CaSO₄2H₂O

= 1.276876 x 10²¹ molecules CaSO₄· 2H₂O   x   6 oxygen atoms / molecule

= 7.661256 x 10²¹  oxygen atoms in 0.364 grams of  CaSO₄·2H₂O

= 7.66 x 10²¹  oxygen atoms in 0.364 grams of  CaSO₄·2H₂O

Hãy tìm công thức hóa học của những oxit có thành phần khối lượng như sau S:50%; C:42,8%; Mn:49,6%; Pb:86,6%

Answers

Answer:

Find the chemical formulas of oxides that contain the following composition:

S:50%; C:42,8%; Mn:49,6%; Pb:86,6%

Explanation:

In the given oxide of sulphur,

50%S is present that means remaining 50% is O.

Divide the % with atomic mass:

S                                     O

50/32= 1.5625            50/16=3.125

divide with smallest ratio:

1.5625/1.5625=1              3.125/1.5625=2

Hence, the formula of oxide is [tex]SO_2[/tex].

Similarly:

Carbon is 42.8% means the reamining % will be O that is 57.2%.

C                                                    O

42.8/12=3.575                         57.2/16=3.575

Divide with smallest ratio:

3.575/3.575=1                            3.575/3.575=1

Hence, the formula of oxide is CO.

Mn is 49.6% means the remining is % is O that is 50.4%.

First divide with atmic mass of respective element, then get the smallest ratio.

That gives the mole ratio of each constituent atom.

Mn                                 O

49.6/55.0=0.90            50.4/16=3.15

0.90/0.90=1                   3.15/0.90=3.5

Multiply with two

2                                        7

Hence, the formula becomes:

[tex]Mn_2O_7[/tex]

Pb is 86.6% means ---remaining 13.4% is O.

Pb                                               O

86.6/207 = 0.418 mol                13.4/16=0.85

0.418/0.418=1                               0.85/0.418=2.0

Hence, the formula is:[tex]PbO_2[/tex]
