Answer:

For a particular chemical reaction, the enthalpy of the reactants is -400 kJ. The enthalpy of the products is -390 kJ. The entropy of the reactants is 0.2 kJ/K. The entropy of the products is 0.3 kJ/K. The temperature of the reaction is 25oC. What can you conclude about this reaction?

It is exergonic

It is endergonic

it is a redox reaction

It is being catalyzed by an enzyme

Consider the condensed structure shown.

neonofarm [45]

Answer:

$C_{5}H_{10}\:C_{2}H_{6}$

Explanation:

Expanded Structure shows all the atoms and the bonds of the molecule. It is important to remember, each Carbon molecule have four bonds, while the Hydrogen just one. So:

1) $C_{5}H_{10}$

Pentene. 5 Carbon molecules, 10 Hydrogen molecules. It's an isomer, so this organic compound has multiple arrangements.

2) $C_{2}H_{6}$

Ethane. 2 Carbon and 6 Hydrogen Molecules. Check it below.

13. What is the total pressure inside the container

nasty-shy [4]

<u>Answer:</u> The total pressure inside the container is 77.9 kPa

<u>Explanation:</u>

Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.

To calculate the total pressure inside the container, we use the law given by Dalton, which is:

$P_T=p_{N_2}+p_{O_2}+p_{Ar}$
