2a) Please change these chemical names into chemical formula to produce the chemical equation, then balance the chemical reaction for " Sodium reacts with calcium nitrate to produce sodium nitrate and calcium metal.
2b) Using the balanced chemical reaction above, solve the following problem,
How many grams of calcium nitrate did I need to react to produce 21.8g of sodium nitrate?(Sorry this reaction actually does not occur because sodium is not higher on Activity series as calcium. BUT do the problem anyway.)
