Answer:
Mass = 100.8 g
Explanation:
Given data:
Mass of sulfur form = ?
Mass of water formed = 37.4 g
Solution:
Chemical equation:
2H₂S + SO₂ → 3S + 2H₂O
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 37.4 g/ 18 g/mol
Number of moles = 2.1 mol
Now we will compare the moles of water with sulfur.
H₂O : S
2 : 3
2.1 : 3/2×2.1 = 3.15 mol
Mass of sulfur:
Mass = number of moles × molar mass
Mass = 3.15 mol × 32 g/mol
Mass = 100.8 g
Answer:
This has already been answered but here is the answer:
2.71×10 molecules of co2 * 1 Mole CO2 /6.022 *10^23 molecules of CO2
= 4.5*10^-14 Mole CO2
1 mole of CO2 has 2 mole oxygen
4.5*10^-14 Mole CO2 *2/1
= 9.0*10^-14 Mole oxygen
There are 17 protons in the nucleus of each atom of an element.
Answer:
Your answer would be C.
Explanation:
A weak base is a base that upon dissolving in water, <u>does not dissociate</u> <u>completely</u>.

The reason why water is so recurrent is because of the general form that says: ACID + BASE → SALT + WATER
I took the liberty of balancing the equations.
