Which of the following is not true for an exothermic reaction?

Chemistry
1 answer:
Gennadij [26K]3 years ago
4 0

Answer:

The false statement regarding an exothermic reaction is: <em>A.</em><em> the products have a higher enthalpy than reactants</em>

Explanation:

An exothermic reaction is a type of chemical reaction that involves the <u>release of energy from the </u><em><u>system to the surroundings</u></em>. Thus <em>increasing the temperature of the surroundings.</em>

In this reaction, the <em>enthalpy or energy of the reactants is greater than the enthalpy or energy of the products</em>.<em> </em>(\Delta H_{f} (Products) < \Delta H_{f} (reactants))

<u>As the enthalpy change of a reaction</u>: \Delta H_{r} = \sum \Delta H_{f} (Products) - \sum \Delta H_{f} (reactants)

Therefore, the <em>enthalpy change for an exothermic reaction is negative</em> (\Delta H_{r} < 0)

How many liters of H2O gas are produced when
anyanavicka [17]
1 mole C3H8 produces 4 moles H2O. So, first we convert 32 grams of propane to moles and then find moles of H2O. Then convert moles of H2O to grams of H2O
Moles of H2O produced = 32 g C3H8 x 1 mole/44 g x 4 moles H2O/mole C3H8 = 2.909 moles H2O
Grams H2O produced = 2.909 moles H2O x 18 g/mole = 52.36 g = 52 g H2O

If 13.8 moles of carbon (c), with a density of 2.26 g/ml, are needed for a chemical reaction, how many milliliters of carbon are
charle [14.2K]

13.8 moles of carbon = 12 g/mol*13.8 or 165.6 grams

165.6 grams/ 2.26 g/mL = 73.27434 or 73.3 mL


I hope this helps!!!!

bija089 [108]

Answer: B or C

Explanation: The question does not include the variable or steps Brian is using so either one could be correct. It has to be the one that he is controlling though. This is because a control group is used to rule out any alternate explanations. Therefore the answer should be the one that he is trying to test out.
