Answer:
pH = -(log 10^-10)
= -(-10)
=10
so the solution is basic in nature

The net ionic equations in
the creation of solid Hg2Cl2 and aqueous Sodium Nitrate (NaNO3) would be:
Hg2(NO3)2 + 2 NaCl
--------> Hg2Cl2 + 2 NaNO3 <span>
Hg2+2 + 2NO3-1 + 2Na+ Cl- ----> Hg2Cl2 + 2Na+ + 2NO3-1
<span>Hg2+2 + 2Cl-1 ------------> Hg2Cl2</span></span>
<span>Ultra violet light is the catalyst that converts 7-dehydrocholesterol to provitamin D3. Ultra violet light can be obtained from the sun. The conversion happens when UVB light hits the skin (where 7-dehydrocholesterol naturally resides), gets absorbed, and us metabolized inside of the body.</span>
Answer:
2.4x10² kcal
Explanation:
As the serving of fish contains 50g of protein that is 4.0kcal/g:
50g × (4.0kcal/g) = <em>200kcal</em>
<em> </em>
And in 4g of fat that is 9.1kcal/g:
4g × (9.1kcal/g) = <em>36.4kcal</em>
<em />
That means the kcal of the serving are:
200kcal + 36.4kcal = 236.4kcal
In 2 significant figures: <em>2.4x10² kcal</em>
<em></em>
I hope it helps!
