Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

Although we usually think of substances as “burning" only in oxygen gas, the
process of rapid oxidation to produce a flame may also take place in other strongly
oxidizing gases. For example, when iron is heated and placed in pure chlorine gas,
the iron "burns" according to the following (unbalanced) reaction:
Fe (s) + Cl2 (g)
→ FeCl3 (s)
How many milligrams of iron(I) chloride result when 15.5 mg of iron is reacted
with an excess of chlorine gas?

If baking soda (sodium hydrogen carbonate) is heated strongly, the following
reaction occurs:
2N.HCO3 (s) → NazCO3 (s) + H2O (g) + CO2 (g)
Calculate the mass of sodium carbonate that will remain if a 1.52-g sample of
sodium hydrogen carbonate is heated.
