Question

Acetylene (C,H,) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen (O2) gas, producing carbon dioxide gas and water vapor. Calculate the moles of acetylene needed to produce 1.90 mol of water. Be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits. X 5 ?

Answer 1

CH₂ +502 2002 + H₂O - 2 GHz + 50₂ &cą + 2H₂O o by equation (2) - 2 moles of acetylene reach with 5 moles of O2 i then 4 moles of co & 2 molo of Ho formel. whe ie 2 morg Cat Ž 5 mol of O₂ = 4 mol y caĚ 2 mol of H₂O a mol of tho 1 mol of tho 190 mol of Ho E a my of CH2 Ž 1 mol of all Ž 1.90 mol of Calta 9 So; moles of autylene required to produce 1.90 mol is equal to 1 1.90 mol of acetylene

Hope it will work. Encourage me by thumbs up.
