Answer:
82.9% Is the percent yield
Explanation:
First, we need to balance the equation.
Ca(CO3) + 2HCl → H2O + CO2 + CaCl2
Since the problem tells you that the excess reactant is Ca(CO3), we just need to Stoichiometry to solve for the theoretical yield.

x 
=120.707 g (theoretical yield)
Take your actual yield of 100g, divide that by 120.707, then multiply that decimical by 100.
When a glacier has equal snow accumulation and wastage. Hope this helps!
Answer:
Explanation: It has been given that the temperature of the water decreases when chromium chloride is dissolved in water. Thus fall in the temperature explains the fact that the bond energies of the reactants have more energy rather than the products.
a) Thus the heat of the solution is endothermic in nature as more energy is needed to break the reactant molecules.
b) The combined ionic bond strength of CrCl2 and inter molecular forces between water molecules must be stronger than the attractive forces between the water molecules and chromium and chloride ions as the reaction is endothermic in nature thus more energy would be required to break the bonds between the reactants hence making them more stronger.
Filtration. A filter is a porous barrier. Heterogeneous means it's a visible mixture, i.e large enough particles to see.
