They form calcium phosphide Ca3P2
6Ca + P4 --> 2Ca3P2
how do you write a balanced chemical formula for this question CaO + H2O ---> Ca(OH)2
Ca + 2H2O = Ca(OH)2+ H2
Ca (OH) 2
Assuming that you are combining the P4 with Cl2 and there is a suffiecient quantity of Cl2 for the P4 to completely react, you will first need a balanced equation which is P4 + 10Cl2 -> 4PCl5. From there, it's mostly stoichiometry. Take the 24g of P4, divide by the molar mass (123.88g/mol) to get the number of moles of P4 that you have (0.194). You then have to convert, using the balanced equation, from moles of P4 to moles of PCl5, in this case multiplying by 4. That will give you the number of moles of PCl5. The stoichiometry should look something like this 24.0 g P4 x (1 mol P4/123.88g P4) x (4 mol PCl5/1 mol P4).
Ca + 2H2O --->Ca(OH)2 + H2 Solution is alkaline
Calcium reacts with water.

Ca + 2H2O = Ca(OH)2+ H2
P4+Cl2 P4+Cl2
Hydrogen and lime Ca + 2 H2O --> H2 + Ca(OH)2
Ca (OH) 2
In an expression p4 is called a term.
Water is added to quicklime the make slaked lime. Calcium hydroxide reacts with water to form calcium hydroxide. CaO + H2O --> Ca(OH)2

Ca + H2SO4 -----> CaSO4 + H2
Ca + 2H2O --->Ca(OH)2 + H2 Solution is alkaline
the color of P4 is light brown
