What is the ph of a neutral solution at a temperature where kw=8.0×10−14?

Chemistry

A neutral solution is when the H⁺ concentration is equal to OH⁻ concentration.
Since there are equal amounts of both H⁺ and OH⁻, solution is neither basic nor acidic, they both react to form water.
kw is the ionic product of water 
kw = [H⁺][OH⁻]
kw = 8.0 x 10⁻¹⁴
since [H⁺]=[OH⁻]
kw =  [H⁺]²
[H⁺]  = √(8x10⁻¹⁴)
[H⁺] = 2.82 x 10⁻⁷ M
pH is calculated using the following equation 
pH = -log [H⁺] 
pH = -log(2.82 x 10⁻⁷ M)
pH = 6.54

Finger [1]

Answer:

Hi there!

I believe you are missing an attachment to this question however

I strongly believe that the answer you are looking for is 85.

Explanation:

If you provide the graph, the rate of strokes in Asian women will be 17 per 1,000 women so all you have to do is multiply 17 by 5 and you get 85

In two or more complete sentences explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps. Write yo
Serggg [28]

Answer:

2KClO3 -------> 2KCl + 3O2

Explanation:

First, in balancing a chemical reaction such as the one given in the question, you should understand that for an equation to be balanced, the number of atoms and ions on both sides of the equation that is the right and left side must be equal. This follows the law of conservation of mass which tells us that matter can neither be created nor destroyed but can be changed into another form.

Next is to begin balancing the equation by identifying and writing down the substances given:

KCl03 ---------> KCl + O2

Next is to count he number of the individual atoms on each side and find out if they are the same on both sides and if not you must follow the next step.

Add a corresponding number and use it to multiply the atoms involved

KClO3 ---------> KCl + O2

Oxygen is 3 on the left side and two on the other side, so we multiply the left hand side by 2 and the right hand side by 3

2KClO3 -----> KCl + 3O2

The potassium and Chlorine are no longer balanced, so you multiply the right had=nd side of KCl by 2.

2KClO3 -----> 2KCl + 3O2

The reactionis herefore balanced as both sides have equal number of atoms and ions.
