What two elements make up a compound xcl?
The compound XCl is made up of the elements X (representing an unknown element) and chlorine (Cl). The subscript indicates that there is one atom of X bonding with one atom of chlorine in the compound.
What is bromine and carbon tetrachloride?
Bromine in carbon tetrachloride is a brown-colored solution and used as a chemical test. When drops of bromine/carbon tetrachloride are added to a solution containing an unknown compound and the brown-colored bromine solution disappears, that means that the unknown compound contains carbon-carbon double bonds (since it absorbed the bromine solution). On the other hand, if the brown-colored bromine solution doesn't disappear then it means that no carbon double bonds are present. This is called a "Bromine Test."
A 1.22g sample of an unknown has a volume of 1.73cm3. What is the density?
They use a number called a mole. This many atoms of an element equals its atomic weight in the periodic table. Molecular weight is the sum of atomic weight. Silver has an atomic weight of 108 grams/mole and Chlorine is 35.4 grams/mole. This makes AgCl 108 + 35.4 = 143.4 grams/mole. The % Chlorine is the atomic weight of Chlorine divided by the molecular weight of AgCl. 1 mole of AgCl would contain 35.4 grams / 143.4 grams = 25% Chlorine by weight. 1.22 grams AgCl would contain (0.25)*(1.22) = 0.30 grams of Cl. To find the Chlorine in the unknown, divide the weight of Chlorine from the experiment by the initial weight of the unknown. 0.30 grams / 0.63 grams = 0.48 = 48% Cl by weight.
How could you lower the pH of the unknown liquid?
You should NEVER add acid (lowering pH) to an unknown liquid (or solid as well), it can be very dangerous. For example: suppose the unknown happens to be hypochlorite (bleach powder solution, desinfectant): when you add acid (any will do) then CHLORINE gas might escape which is a VERY TOXIC gas, causing acute pulmonary (o)edema.

Chloride Cl-: Ne,3s2,3p6 : has 1 valence electron accepted from metal XChlorine Cl : Ne,3s2,3p5 : neutral can donate 1, 3, 5 or 7 val. electrons, remains: 3p5->4,2,0 and 3s2->0 respectively, '->' means 'lowering to')Chlorine? Cl?: Ne,3s2,3p65 as in the questioned: unknown 65 is impossible,(mail my Mess.Board if you can give an other question.JdQ)
