Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
Im unsure :( maybe try looking up a calorie calculator
Explanation:
The total mass is:
100 g + 200 g
= 300 g
The mass of salt is:
0.20 (100 g) + 0.10 (200 g)
= 20 g + 20 g
= 40 g
So the concentration is:
40 g / 300 g
≈ 13.33%
Round as needed.
First, we have the ionic elements. This type of elements involved completely transferring of one ion to another in order to form a bond. There is also the type which forms the covalent bond which involves only sharing of the electrons. Those that exhibits the polar bonds and also the hydrogen bonding.
