Using stoichiometry, solve a and b using the following balanced equation: CaC2 + 2 H2O -> C2H2 + Ca(OH)2

a. How many grams of acetylene (C2H2) are produced by adding excess water to 5.00g CaC2?

b. How many moles of CaC2 are needed to react completely with 1.92x10^24 moles of H2O?

Thanks )

Need what is special about water as a compound? how does water regulate climate? what drives water evaporation?   why is the water vapor fresh water when it rises from the ocean? why might freshwater in the form of snow take longer to enter the water cycle again than liquid precipitation?   what is an aquifer? what role do people play in the water cycle? plz just answer as many as you can ! thx if you !

If you reacted 450 g of trimethylgallium with 300 g of arsine, what mass of gaas could you make?
