What are the two items needed to make a gas that can be weighed?
To make a gas that can be weighed, you need a container to hold the gas and a scale to measure its weight.
How many grams of calcium hydride are needed to form 4.850 g of hydrogen gas?
To calculate the amount of calcium hydride needed to form 4.850 g of hydrogen gas, you need to use the molar ratio between calcium hydride (CaH2) and hydrogen gas (H2), which is 1:2. Therefore, you would need half as many grams of calcium hydride as the grams of hydrogen gas produced, so 2.425 g of calcium hydride would be needed.
Which gas in the air is needed for fuels to burn?
oxygen is needed for fuel to burn
How many grams of gas are needed to react with 348.5 grams of oxygen?
To determine the amount of gas needed to react with 348.5 grams of oxygen, you need to know the balanced chemical equation of the reaction. Then, use the stoichiometry of the reaction to calculate the amount of gas required based on the molar ratio between the gas and oxygen in the reaction.
What gas in the atmosphere is needed by all living things?
Oxygen is the gas in the atmosphere needed by all living things for the process of respiration. Oxygen is taken in by organisms to produce energy through the oxidation of their food.
