Assuming pure calcium carbide:
CaC2 + 2 H2O → C2H2 + Ca(OH)2
Molar mass of CaC2 = 64.1
Molar mass of water =18
∴ no mol of CaC2 = 492/64.1=7.68mol
∴ no mol H2O =2*7.68=15.35mol
∴mass H2O = 15.35*18 = 276.3g of water
The mass of silver nitrate is 30,6 g.
63 g of water are needed.
To determine the grams of hydrochloric acid (HCl) needed to react completely with 4.6 g of calcium (Ca), we first need to use the balanced chemical equation for the reaction: [ \text{Ca} + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2 ] From the equation, one mole of calcium reacts with two moles of hydrochloric acid. The molar mass of calcium is approximately 40.08 g/mol, so 4.6 g of calcium corresponds to about 0.115 moles of Ca. This means it would require about 0.230 moles of HCl. The molar mass of HCl is approximately 36.46 g/mol, so you would need about 8.38 g of HCl to react with 4.6 g of calcium.

128 g of oxygen are needed.
Calcium carbide and water react to form calcium hydroxide and acetylene gas. This reaction is commonly used in the production of acetylene for welding and cutting purposes.
For every 40 grams of calcium (Ca), 32 grams of oxygen (O) will be needed to react. This is based on the chemical formula for calcium oxide (CaO), where one calcium atom reacts with one oxygen atom to form one molecule of CaO.
The mass of silver nitrate is 30,6 g.
To determine the amount of calcium needed, you need to balance the chemical equation for the reaction between calcium and water. The equation is Ca + 2H2O → Ca(OH)2 + H2. Then, convert the mass of water to moles, use the stoichiometry of the balanced equation to find the moles of calcium required, and convert that to grams of calcium.
The balanced chemical equation for the reaction is: 2Ca + O2 --> 2CaO This equation shows that for every 2 moles of calcium that react with 1 mole of oxygen, 2 moles of calcium oxide are formed. Since the molar mass of Ca is 40 g/mol, and the molar mass of CaO is 56 g/mol, the 10 grams of calcium would react with 7 grams of oxygen to form 14 grams of calcium oxide.

Carbide is typically produced by reacting carbon with a metal, such as calcium or tungsten, at high temperatures. The process involves heating the metal and carbon source in an electric arc furnace until they chemically react to form carbide. The resulting carbide can be further processed and shaped into various products.
When carbide reacts with water, it produces acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2). The reaction is highly exothermic, releasing a large amount of heat energy. This reaction is commonly used in carbide lamps to produce a bright, white light.
