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
The formula of Silver (III) Sulfide is Ag2S3.

The reason for this is because nonmetals, have close to fulfilling an octet and need to gain few more electrons to do this, not to lose more. Nonmetals, because of the fact they need only few more electrons to satisfy their octet they would receive or share electrons to do this.
The property that nonmetals have are that they are very electronegative, they possess a strong affinity to pull electron density closer, because they possess fewer electron shells and possess even protons this allows for this.
Answer:
There are a couple different types of precipitation, though it is generally taken to mean a synonym for rain. It includes rain, snow, sleet, and hail. With the increase in global warming, there is more precipitation. In general, the type of precipitation varies with the season; we see less in the summer of all types, more snow, sleet, and hail in the winter, and more rain in the temperate seasons like fall.
Answer:
Moles of TNT = 2.38 moles
Explanation:
First , calculate the molar mass of the compound TNT
The formula is : C7H5N3O6
How to calculate molar mass?
Molar mass : It is the mass of substance in grams which is present in 1 mole of the compound.It is calculated by:
Molar mass = Number of atoms x the atomic mass of the element
Atomic mass of the elements are given below :
C = 12.0107
H = 1.0079
N = 14.0067
O = 15.9994
Molar mass of C7H5N3O6 =
= (7 x C) + (5 x H) + (3 x N) + (6 x O)
= 7(12.0107) +5(1.0079) + 3(14.0067) + 6(15.9994)
Molar mass = 227 .13 gram/mole
Mole are calculated using the formula:
Given mass = 539.88 grams
Molar mass = 227.13 g/mole
= 2.3769
Moles = 2.38 moles
