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.

hot spring
Explanation:
The mineral water in hot springs can also help reduce stress by relaxing tense muscles. Meanwhile as your body temperature rises in the bath, and then cools once you exit can also help you relax and fall into a deeper sleep.
Carbohydrates are substances that are found in foods such as bread and pasta, which provide the body with heat and energy. Chemically, carbohydrates are made of three kinds of elements namely carbon , hydrogen and oxygen.
Carbohydrates are separated into two main categories, simple carbohydrates and complex carbohydrates.
Simple carbohydrates are those that contain one or two sugar molecules linked together. Complex carbohydrates are those that contain three or more sugar molecules linked together. In some cases these chains can contain hundreds of sugar molecules.
