The correct answer for the given question about Enthalpy of vaporisation is ( Volume of liquid in L x 1000 g/L x ΔHvap cal/gm ) where ΔHvap = 540 cal/gm (in case of water).

What is Enthalpy of vaporisation ?

The amount of energy (enthalpy) required to convert a portion of a liquid into a gas is known as the enthalpy of vaporisation, abbreviated as ΔHvap  and also referred to as the latent heat of vaporisation or heat of evaporation.

How to solve this question?

Let E be the energy required to calculate the energy required to vaporise a volume of liquid.

Then,

E = Volume of liquid in L x Density of liquid in gm/L  x ΔHvap in cal/gm

and E will came out in calorie.

E = Volume of liquid in L x 1000 g/L x 540 cal/gm --- (in case of water)

Thus we can conclude that to calculate the energy required to vaporise a volume of liquid, we can use the formula with ΔHvap which is E = (Volume of liquid in L x Density of liquid g/L x ΔHvap cal/gm ) and the answer will be in calorie.

ionic bonds show which characteristics that arent seen in covalent bonds

Answers

Ionic bonds are when one atom is a metal and the other is a nonmetal. One atom has a high electronegativity value while the other value is relatively low. Electrons are transferred in ionic bonds.

In a covalent bond atoms are equal or similar in electronegativity values and both of the atoms are also non metals. Electrons are shared in covalent bonds.

State with reasons, whether sulphur dioxide is acting as an oxidizing agent or a reducing agent in each of the following reactions:

•2H2S(g) + SO2(g) -> 2H2O(l) + 3S(s)

•SO2(g) +H2O(l) +NaClO(aq) -> NaCl(aq) + H2SO4(aq)

Answers

Answer:

A) oxidizing agent is SO2

B) NaClO is the oxidizing agent

Explanation:

A) This is a redox reaction in which oxidation and reduction occur simultaneously.

Thus, in 2H2S(g) + SO2(g) -> 2H2O(l) + 3S(s);

H2S is reduced as follows;

H2S → S + 2H+ + 2e−

We can see that SO2 has been reduced while H2S gets oxidized since it has changed state from - 2 to 0 . Thus sulphur dioxide is the oxidizing agent.

B) SO2(g) + H2O(l) + NaClO(aq) -> NaCl(aq) + H2SO4(aq)

In this, SO2 undergoes oxidation and NaClO is the oxidizing agent

How many atoms of phosphorus are in 7.00 mol of copper(II) phosphate?

Answers

Answer: The number of phosphorus atoms in given amount of copper(II) phosphate is [tex]8.431\times 10^{24}[/tex]

Explanation:

We are given:

Moles of copper(II) phosphate [tex]Cu_3(PO_4)_2[/tex] = 7.00 mol

1 mole of copper(II) phosphate contains 3 moles of copper, 2 moles of phosphorus and 8 moles of oxygen atoms

Moles of phosphorus in copper(II) phosphate = [tex](2\times 7.00mol[/tex]

According to the mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of particles

So, 7.00 moles of copper(II) phosphate will contain = [tex](2\times 7\times 6.022\times 10^{23}=8.431\times 10^{24}[/tex] number of phosphorus atoms.

Hence, the number of phosphorus atoms in given amount of copper(II) phosphate is [tex]8.431\times 10^{24}[/tex]

What are most likely the values of the quantum numbers I and mI for an

B. I = 3; mI = -1/2, + 1/2
C. I = 0, 1, 2, 3; mI = -1, 0, 1
D. I = 1; mI = -1, 0, 1

Answers

Answer:

I think its D

Not too sure

The quantum numbers denote the position of an electron in the orbital. The angular momentum quantum number (l) and magnetic quantum number (ml) of the 3p orbital is I = 1; mI = -1, 0, 1. Thus, option D is correct.

What are quantum numbers?

The quantum numbers are conserved quantities used to describe the energy and the position of the electron in the atomic orbital. The azimuthal, principal, magnetic, and spin are the four quantum numbers.

The angular momentum quantum number (l) represents the orbital shape and depends on the principal quantum number, n. The magnetic quantum number (ml) represents the orientation.

If an electron is in a 3p orbital then,

n = 3

l = 1

ml = -1, 0, 1

Therefore, option D. 3p orbital contains I = 1; mI = -1, 0, 1.

The reaction that occurs at the cathode of a given galvanic cell is:

Cu²⁺  + 2e⁻  → Cu

What is Galvanic Cell?

A galvanic cell can be defined as an electrochemical cell that converts the chemical energy of spontaneous redox reactions into electrical energy. The galvanic cell makes use of chemical reactions to generate electrical energy.

A galvanic cell consists of two half-cells and a salt bridge. Each half-cell further contains an electrode dipped into an electrolyte. When both electrodes are dipped in the same electrolyte, then there is no need for a salt bridge.

At the anode, an oxidation reaction occurs at this electrode. At the cathode, reduction occurs at this electrode. The anode has a negative potential with respect to the solution while the cathode has a positive potential with respect to the solution.

As in the question, the reduction of Cu²⁺ has a positive reduction potential. Therefore, the reduction of the copper will occur at the cathode.

Answers

Answer:

6.25mol

Explanation:

Using the following formula;

Mole = mass ÷ molar mass

According to this question, there are 100 grams of methane (CH4)

Molar Mass of methane (CH4) = 12 + 1(4)

= 12 + 4

= 16g/mol

mole = 100/16

mole = 6.25moles

Therefore, there are 6.25moles of methane in 100g
