Answer: placing coefficients
Explanation: In a balanced chemical equation, the total number of atoms of each element present is the same on both sides of the equation. Stoichiometric coefficients are the coefficients required to balance a chemical equation. These are important because they relate the amounts of reactants used and products formed.
Answer:
A. Energy is released
Explanation:
Energy is only released when chemical bonds are formed.
Answer:
Option B: It remains unused during the reaction
Explanation:
Just took the test and got it right.
Answer:
A 1.0 g sample of propane, C3H8, was burned in the calorimeter.
The temperature rose from 28.5 0C to 32.0 0C and the heat of combustion 10.5 kJ/g.
Calculate the heat capacity of the calorimeter apparatus in kJ/0C
Explanation:
Given,
The heat of combustion = 10.5kJ/g.
Substitute these values in the above formula to get the value of heat capacity of the calorimeter.
Answer:
The heat capacity of the calorimeter is
