Answer:

E. All of the above are true.

Explanation:

<em>Which of the following statements is TRUE?</em>

<em>A. State functions do not depend on the path taken to arrive at a particular state.</em> TRUE. State functions like enthalpy (ΔH) and internal energy (ΔE) do not depend on the trajectory, but on the initial and final state.

<em>B. Energy is neither created nor destroyed, excluding nuclear reactions.</em> TRUE. Only in nuclear reactions can energy (E) can be transformed in matter (m) and vice-versa according to Einstein equation: E = m . c² (c is the speed of light).

<em>C. ΔHrx can be determined using constant pressure calorimetry.</em> TRUE. The enthalpy of reaction is the heat involved at constant pressure.

<em>D. ΔErx can be determined using constant volume calorimetry.</em> TRUE. The internal energy of reaction is the heat involved at constant volume.

How many molecules are in 3 moles of CO2?
Alenkinab [10]

Answer:

<h2>1.806 × 10²⁴</h2>

Explanation:

The number of molecules can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 3 × 6.02 × 10²³

We have the final answer as

<h3>1.806 × 10²⁴</h3>

Hope this helps you
