Answer: 0.736 g
Explanation:
To calculate the moles, we use the equation:
By Stoichiometry:
1 mole of ozone reacts with 1 mole of nitric oxide
to form 1 mole of nitrogen dioxide
0.016 moles of ozone reacts with= of nitric oxide to form 0.016 mole of
Thus ozone is the limiting reagent as it limits the formation of products and nitric oxide is the excess reagent as (0.019-0.016) g= 0.003 g remains as such.
Mass of
0.736 g of will be produced.
Answer: Option (D) is the correct answer.
Explanation:
Enthalpy is defined as the amount of energy needed or removed from a substance. It is represented by .
Basically, it is the change in enthalpy and it represents the difference between the energy used in breaking bonds and the energy released in formation of bonds in a chemical reaction.
It is also known as heat of reaction. When value of is positive then it means heat is absorbed in the chemical reaction.
When value of is negative then it means that heat is released in the chemical reaction.
Whereas entropy means the measure of randomness. It is represented by . We cannot calculate entropy but we can measure the change in entropy.
Thus, we can conclude that all of the statements regarding the symbol "ΔH" are correct except it that can be called entropy change.
