well, the movie lasted 1:38   so.... and she finished it at 1:10pm.

1:10pm minus 1 hour?  12:10pm.

12:10 pm minus 10 and minus 28 minutes?   12:10 - 00:10 = 12:00pm, 12:00 - 00:28 minutes = 11:32am.

Answer: 11:32

Step-by-step explanation:

Answer:

0.10 M AlCl₃.

Explanation:

We can calculate the concentration of chloride ion [Cl⁻] in each salt:

• 0.10 M MgCl₂:

MgCl₂ is dissociated according to the reaction:

MgCl₂ → Mg²⁺ + 2Cl⁻,

Every 1 mol of MgCl₂ produces 2 mol of Cl⁻.

So, [Cl⁻] = (2)*(0.1 M) = 0.2 M.

• 0.10 M AlCl₃:

AlCl₃ is dissociated according to the reaction:

AlCl₃ → Al³⁺ + 3Cl⁻,

Every 1 mol of AlCl₃ produces 3 mol of Cl⁻.

So, [Cl⁻] = (3)*(0.1 M) = 0.3 M.

• 0.05 M CaCl₂:

CaCl₂ is dissociated according to the reaction:

CaCl₂ → Ca²⁺ + 2Cl⁻,

Every 1 mol of CaCl₂ produces 2 mol of Cl⁻.

So, [Cl⁻] = (2)*(0.05 M) = 0.1 M.

• 0.10 M LiCl:

LiCl is dissociated according to the reaction:

LiCl → Li⁺ + Cl⁻,

Every 1 mol of LiCl produces 1 mol of Cl⁻.

So, [Cl⁻] = (1)*(0.1 M) = 0.1 M.

So, the solution will have the highest concentration of chloride ions is AlCl₃.

From the given options, the solution of 0.10M AlCl₃ is the one that has the highest concentration of chloride ions. 

To know which of the given solutions has the highest concentration of chloride ions, we must evaluate each of them.

1) 0.10 M MgCl₂

We can see that in 1 mol of MgCl₂, we have 1 mol of Mg²⁺ and 2 moles of Cl⁻ ions, so if the initial concentration of MgCl₂ is 0.10 M we have:

[Cl^{-}] = \frac{2\: moles\: Cl^{-}}{1 \: mol\: MgCl_{2}}*\frac{0.10 \:mol\: MgCl_{2}}{1 L} = 0.20 M 

Hence, in this solution we have 0.20 M of chloride ions.

2) 0.10 M AlCl₃

In 1 mol of AlCl₃, we have 1 mol of Al³⁺ and 3 moles of Cl⁻, so the concentration of Cl⁻ is:

[Cl^{-}] = \frac{3\: moles\: Cl^{-}}{1 \: mol\: AlCl_{3}}*\frac{0.10 \:mol\: AlCl_{3}}{1 L} = 0.30 M 

Then, the concentration of chloride ions in this solution is 0.30 M.

3) 0.05 M CaCl₂

We can notice that in 1 mol of CaCl₂ we have 1 mol of Ca²⁺ and 2 moles of Cl⁻. The concentration of Cl⁻ is:

[Cl^{-}] = \frac{2\: moles\: Cl^{-}}{1 \: mol\: CaCl_{2}}*\frac{0.05 \:mol\: CaCl_{2}}{1 L} = 0.10M

So, the concentration of the Cl⁻ ions is 0.10 M.

4) 0.10 M LiCl

In this case, in 1 mol of LiCl we have 1 mol of Li⁺ and 1 mol of Cl⁻, so the concentration of the chloride ions is:

[Cl^{-}] = \frac{1\: moles\: Cl^{-}}{1 \: mol\: LiCl}*\frac{0.10 \:mol\: LiCl}{1 L} = 0.10 M

Hence, in this solution the concentration of the Cl⁻ ions is 0.10 M.

Therefore, the solution 0.10M AlCl₃ has the highest concentration of chloride ions.

I'm not sure if It will make any sense

but a cheap hambuger is made poorly

probably maybe even roughly good at its best if not just not as good as a average priced buger and the pulled tooth

Answer:

A. The energy in nuclear fission produces chemicals that harm the environment.

Explanation:

Nuclear power plants produce radioactive wastes such as the uranium mill tailings, used reactor fuel, and other radioactive wastes.

Radioactivity of this waste lasts forever and is very harmful to the living world.

During accidents in nuclear power plants, enriched uranium ends up in the environment, this leads to health problems such as kidney diseases.
