In some kind of a 0.800 m ba(oh)2 solution, each individual ion has a concentration of 1.81M.
<h3>What are the 5 most common electrolytes?</h3>
Together with magnesium, calcite, phosphate, and bicarbonates, salt, potassium, & chloride are the important electrolytes. We obtain electrolytes from our diet and drinks. Unbalanced amounts of these electrolytes might result in either low or high levels.
<h3>Briefing:</h3>
In a solution of Ba(OH)2 at a concentration of 0750 M, Ba2+ is the predominant ion. = 0.800M and OH⁻ = 1.50 M.
The dissociation equation is:
Ba(OH)²(s)=Ba²+aq+2OH-aq
Using the Ba(OH)2 mole ratio: Ba₂⁺which is 1: 1 the concentration of Ba² is = 0.750M
By utilising Ba(OH)2's mole ratio: which is 1:2 the concentration of
OH=0.800*2/1
=1.81M
Individual ion concentration is therefore ba(oh)2 = 0.800M & = 1.81M.

Answer:
292.4 g
Explanation:
- 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
First we <u>convert 53.7 g of Al into moles</u>, using its<em> molar mass</em>:
- 53.7 g ÷ 27 g/mol = 1.99 mol Al
Then we <u>convert Al moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.99 mol Al * = 2.98 mol H₂SO₄
Finally we <u>convert 2.98 moles of sulfuric acid into gram</u>s, using its <em>molar mass:</em>
- 2.98 mol H₂SO₄ * 98 g/mol = 292.4 g
I think the answer is A B C I’m not completely sure though
