Answer:
In a chemical formula, the elements in a compound are represented by their chemical symbols, and the ratio of different elements is represented by subscripts.
Explanation:
Water is a polar molecule
Answer:
The reaction produces insoluble lead (II) sulphate which coats the surface of lead (II) nitrate [Pb(NO3)]
First, let's determine the number of moles of carbon atoms by using molar mass. Then, using Avogadro's number, we can find the number of C atoms:
*1 mole of C3H8O= (12.0x3)+(1.0x8)+(16.0x1) = 60.0g/mol
25.0 grams C3H8O x (1 mole C3H8O/60.0 grams) = 0.417 mol
0.417mol C3H8O has (3 x 0.417 moles) C atoms = 1.251 moles C atoms
1.251 moles C atoms x(6.022x10^23 atoms/mol) = 9.42x10^23 C atoms.
The answer is in 3 significant figures, as that's what we have in the given, and we matched it with our rounding of the atomic masses from the periodic table.
You can do this all in one equation written left to right, just exclude the intermediate answers. Just easier to show it this way on the computer screen.
The effect of increasing acidity on the solubility of the compounds is when the acidity of the solution is increased, the solubility of the compound is also increased. This is because the molecules in the compound acquire charge which enables the molecules to be dissolved easily in the solution. An uncharged molecule has a minimal value for solubility.
