Answer:
A 0.239mol
Explanation:
From the equation:
We were given that 10g of iron was involved in this chemical reaction
We can establish that :
3moles of Fe would produced 4 moles of Hydrogen gas
Therefore:
Number of moles of iron = mass of Fe / mloar mass of iron
Mass of Fe = 10g
Molar Mass of Fe = 55.85g/mol
Therefore, number of moles of iron= 10/55.85
Number of moles of iron = 0.179mol
3moles of Fe would produced 4 moles of Hydrogen gas
So, 0.179mol of Fe would give 0.179x4/3
The number of mole of Hydrogen gas produced is 0.239mol.
The ratio for mg and ag is 1:2 therefore, 0.96 mole silver is produced, use the conversation method.
Explanation:Photosynthesis is important because the earth and all of the creatures in the sea and land need the plants to be able to feed themselves with the help of the sun and with cellular respiration, those plants are able to take in the carbon dioxide that we give and make into oxygen with we need. there fore without them we would not be able to exist.
