Given that 56 grams of an ideal gas occupies 6.9 litres (dm) at STP (Standard temperature a
nd pressure, OC and 101,325 Nm), what is its
volume at 100°C and a pressure of 76.0 cm of mercury? Do not use the
general gas equation to solve this problem.

​

Calcium hydride (cah2) reacts with water to form hydrogen gas: cah2(s) + 2h2o(l) → ca(oh)2(aq) + 2h2(g) how many grams of cah2 are needed to generate 45.0 l of h2 gas at a pressure of 0.995 atm and a temperature of 32 °c?

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

Miner's coal distributors does not mine coal itself, nor does it even store or handle the coal. instead, miner's solicits orders for low sulfur coal from other firms, then purchases the required amount from suppliers and directs them to ship the coal to its customers. what is miner's
