Salt is a chemical compound formed for the reaction of an acid with a base.
Because if you follow a fitness plan you can get done a lot of stuff that you can't without a plan so like you make a plan of what you are going to do instead of just doing random fitness stuff
Answer:
Mass = 14.0 g
Explanation:
Given data:
Mass of mercury nitrate = 22.17 g
Mass of mercury formed = ?
Solution:
Chemical equation:
Hg(NO₃)₂ + 2K → 2KNO₃ + Hg
Number of moles of mercury nitrate:
Number of moles = mass/molar mass
Number of moles = 22.17 g / 324.6 g/mol
Number of moles = 0.07 mol
Now we will compare the moles of Hg(NO₃)₂ and mercury.
Hg(NO₃)₂ : Hg
1 : 1
0.07 : 0.07
Mass of mercury:
Mass = number of moles × molar mass
Mass = 0.07 mol × 200.6 g/mol
Mass = 14.0 g
The number of carbon atoms in an alcohol affects its solubility in water, as shown in Table 13.3. As the length of the carbon chain increases, the polar OH group becomes an ever smaller part of the molecule, and the molecule becomes more like a hydrocarbon. The solubility of the alcohol decreases correspondingly.
