If there is more water than anything else, water is the solvent.
If water is a minor component of the solution, the water is a solute.
For example, "190 proof alcohol" is 95 % alcohol and 5 % water. In this solution, alcohol is the solvent and water is the solute.
Answer:
=<em><u> 1.7 M</u></em>
Explanation:
Molecular mass of NaCl = ( 23+35.5 ) = 58.5g
58.5g of NaCl are weighed by 1 mole of NaCl
10.0g of NaCl will be weighed by ( 10÷58.5 )
<em> <u>= 0.17 moles of </u><u>NaCl</u></em>
100mL = ( 100÷1000)L = 0.1L
0.1L of a solution is occupied by 0.17 moles of NaCl
<u>1L</u> of solution will be occupied by [(1÷0.1)×0.17]
=<em><u>1</u></em><em><u>.</u></em><em><u>7</u></em><em><u> </u></em><em><u>M</u></em>
The correct answer is 1. Lose electrons and become positive ions.

Answer:
<h2>2.7 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
We have the final answer as
<h3>2.7 g/mL</h3>
Hope this helps you
H₂O₂ + 2FeSO₄ + H₂SO₄ → Fe₂(SO₄)₃ + 2H₂O
H₂O₂ + 2H⁺ + 2e⁻ → 2H₂O k=1
Fe²⁺ → Fe³⁺ + e⁻ k=2
H₂O₂ + 2H⁺ + 2Fe²⁺ → 2H₂O + 2Fe³⁺
