Answer:
A sample that has low pH, will have a [OH⁻] < 1x10⁻⁷
Explanation:
Kw = 1x10⁻¹⁴
[H₃O⁺] = 1x10⁻⁷
[OH⁻] = 1x10⁻⁷
If pH is very low, [H₃O⁺] > 1x10⁻⁷
For example, [H₃O⁺] = 1x10⁻³ M
- log [H₃O⁺] = pH
- log 1x10⁻³ M = pH = 3
[OH⁻] will be < 1x10⁻⁷
For the example we made before
pH = 3
pOH = 14 - pH → 11
10^-pOH = [OH⁻]
10⁻¹¹ = 1x10⁻¹¹
Answer:
yes
Explanation:
that is all due to temperature
Answer: 16 g/mol
Explanation: Molarity is Moles/Liters or Mol/L
(0.50 mol/L)(1.30L) = 0.65mol
(cancels out L)
Molar mass is g/mol so...
10.5g/0.65mol = 16.1 g/mol
Rounded to 2 sig figs is 16 g/mol
Answer : The number of silver atoms produced will be 
Explanation : Given,
Number of atoms of copper = 
The given balanced chemical reaction,
From the balanced chemical reaction we conclude that,
As, 
number of copper atoms react to give 
number of silver atoms.
So, number of copper atoms react to give 
number of silver atoms.
Therefore, the number of silver atoms produced will be
