Q1.
In an experiment, ammonia gas is made by heating a mixture of ammonium chloride and calcium
hydroxide.

2NH4Cl(s) + Ca(OH)2(S) = CaCl2(s) + 2NH3(g) + 2H2O(l)

10.0 g of ammonium chloride is added to an excess of calcium hydroxide.

Calculate the maximum volume of ammonia gas that could be formed.
(relative atomic mass H = 1.00, N = 14.0, 0 = 16.0 and Ca = 40.0; one mole of any gas occupies 24 dm3
at room temperature and pressure)

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
