Answer:
2AgNO3 -> 2Ag + 2NO2 + O2
K2CO3 -> K20 + CO2
Answer:
I would use calorimetric to determine the specific heat and I would measure the mass of a sample
Explanation:
I would use calorimetry to determine the specific heat.
I would measure the mass of a sample of the substance.
I would heat the substance to a known temperature.
I would place the heated substance into a coffee-cup calorimeter containing a known mass of water with a known initial temperature.
I would wait for the temperature to equilibrate, then calculate temperature change.
I would use the temperature change of water to determine the amount of energy absorbed.
I would use the amount of energy lost by substance, mass, and temperature change to calculate specific heat.

<u>Answer:</u> The moles of KHP in the sample is
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of KHP = 0.2000 g
Molar mass of KHP = 204.22 g/mol
Putting values in above equation, we get:
Hence, the moles of KHP in the sample is
