In the chemical reaction process
C (s)+ O2 (g)>CO2(g)

2.1 What volume of CO2 can be produced at STP if you start with 3 moles of
oxygen gas? [2]

2.2 What mass of CO2 can be produced from 1,5 moles of oxygen gas? [2]

2.3 What mass of CO2 can be produced from 12g of carbon? [2]

Which is a characteristic of mixtures?

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
