Answer:
1. 1g/ml
Explanation:
1. Density is mass divided by volume (g/mL).
10g/10mL = 1 g/mL
2. When you already know the density and the volume, you can use the density as a unit converter.
3. It's the same with density and mass.
The answer is a. a homogenous mixture
Explanation:
As it is given that the initial concentration of sulfuric acid is 0.010 M.
Hence, the ICE table for first dissociation of sulfuric acid is as follows.
Initial: 0.010 0 0
Change: -0.010 +0.010 +0.010
Equilibrium: 0 0.010 0.010
When second dissociation of sulfuric acid occurs which is partial then the ICE table will be as follows.
Initial: 0.010 0 0.010
Change: -x +x +x
Equilibrium: 0.010 - x x 0.010 + x
Since, it is given that . Hence, formula for is as follows.
x = 0.0045
Hence, by using the equilibrium concentrations from the table and value of x we get the following.
- = x,
= 0.0045 M
- = 0.010 - x
= 0.010 - 0.0045
= 0.0055 M
- = 0.010 + x
= 0.010 + 0.0045
= 0.0145 M
Neutrons have no charge, protons have a +1 charge and electrons have a -1 charge so your net charge = +8 -10 so your net charge is -2
