What volume of 0.300 M calcium chloride contains 3.50g of calcium chloride
3.50g CaCl2 × (1mol CaCl2 /110.98g CaCl2)= 0.0315 molesMolarity = no. of moles / volume 0.300 = 0.0315 / volume Volume = 0.0315/0.300Volume = 0.105 L

A 1.5dm3 of potassium chloride (KCl) has a concentration of 0.5mol/dm3.
How many grams of potassium chloride are present?
Given the atomic masses:
K = 39 and Cl = 35.5
n = C*V n(KCl) = 0.5mol/dm3*1.5dm3 = 0.75 mol M(KCl) = 39 + 35.5 = 74.5 g/mol m(KCl) = n*M = 0.75mol*74.5g/mol = 55.875 g

Is potassium hyrdogen carbonate + hydrogen chloride -> potassium chloride + water + carbon dioxide a combustion reaction
No.Combustion reaction - ecsotermical prosecc, with intensiv burn energy (May be hv)this would be called neutralisation, if you take equivival ammount. Also or acid-base reaction
