"When 0.869g sample of C7H5N3O6 is burned in a bomb calorimeter, the temperature increases from 22.5° C to 28.5°C. The heat capacity of the calorimter is 494 J/°C and it contains 550 grams of water. Find the following rounding all answers to the nearest whole number
Find the (q) H20 in joules
Find the (q) cal in joules
Find the (q) rxn in joules
Find the (delta)
for the run in kj/mol (sign does matter)

Pbco3 –> pbo+ co2. how many liters of carbon dioxide gas is produced from the decomposition of 32 grams of lead (ll) carbonate?

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol
