The volume required : 0.2 L
<h3>Further explanation</h3>
Given
500ml of 0.1M potassium dichromate (vii)
0.25 solution
Required
The volume
Solution
We can use dilution formula :
M₁V₁=M₂V₂
M₁ = 0.25
M₂ = 0.1
V₂ = 500 ml = 0.5 L
The initial volume taken :
V₁=(M₂V₂)/M₁
V₁=(0.1 x 0.5)/0.25
V₁=0.2 L
I think 400 force is required, although i am not that sure. Hope this helps!
Answer:
water and salt
Explanation:
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

Answer:
6.8g of solute are needed
Explanation:
Percent by mass, (w/w%) is defined as the mass of solute in 100g of solution. A solution that is 3.4% contains 3.4g of solute in 100g of solution. That means to make 200g of solution are required:
200g solution * (3.4g solute / 100g solution) = 6.8g of solute are needed
