Calculate the volume (mL) of 1.0 M potassium carbonate (K2CO3) needed to prepare 5.0 g of the COBALT pigment. This is where the balanced chemical equation comes in. You should be able to relate the moles of pigment to the moles of K2CO3, and from that calculate the volume of 1.0 M K2CO3 solution needed

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.

The following reaction shows sodium carbonate reacting with calcium hydroxide. na2co3 + ca(oh)2 → naoh + caco3 how many grams of naoh are produced from 20.0 grams of na2co3? (molar mass of na = 22.989 g/mol, c = 12.01 g/mol, o = 15.999 g/mol, ca = 40.078 g/mol, h = 1.008 g/mol) 12.2 grams 15.1 grams 24.4 grams 30.2 grams

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
