How do you make calcium hydroxide (Ca(OH)2) from Calcium carbonate (CaCO3) and what are the equations.

Thermally decompose the calcium carbonate:CaCO 3 -> CaO + CO 2 Now mix the CaO with water:CaO + H 2 O -> Ca(OH) 2

Integrate (x^3 - x^2 - 5x + 7) with respect to x.

Remember to integrate you +1 to the power and divide by the new power:(x 3+1 /3+1) - (x 2+1 /2+1) - 5(x 1+1 /1+1) + 7(x 0+1 /0+1) + CDONT FORGET YOUR CONSTANTx 4 /4 - x 3 /3 - 5x 2 /2 + 7x + C

Name the type of reaction that takes place when calcium carbonate is heated strongly?

This is called thermal decomposition. CaCO 3 decomposes into calcium oxide (CaO) and Carbon Dioxide (CO 2 ).
