Sodium nitrate can be heated in an environment with excess hydrogen to form
water. The two-step process is:
33
2 NaNO3 → 2 NaNO2 + O2
2 H2 + 02 → 2 H20
36
How many grams of sodium nitrate (NaNO3) are required to form 90.0 grams of
water?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
