How is energy produced in the sun core

Chemistry
2 answers:
BaLLatris [955]3 years ago
6 0

A reaction called nuclear fusion turns hydrogen atoms into helium. The by-product of nuclear fusion in the Sun's core is an enormous quantity of energy that is released and that emanates outward toward the surface of the Sun then into the solar system way beyond it. Moreover, the Gama rays created in the core moves through the gases of Sun and it takes about a million years to make it to its surface as they crash into atoms. Throughout the travel it turns into visible light and infra red waves..The time period differs in dissimilar calculations. Others say it probably takes 20,000 years to get to the surface.

a compound contains 69.94 percent iron and 30.06 percent oxygen. what is its molecular formula if the molar mass of the compound
anyanavicka [17]
The percentages are given in weight. You need to transform them into moles.

Take a basis of 100 grams of compound. Then there are 69.94 grams of iron and 30.06 grams of oxygen.

Use the atomic masses of iron and oxygen to obtain each number of moles.

Molar mass of iron: 55.85 g/mol
# moles of iron = 69.94 g / 55.85 g/mol = 1.252

Molar mass of oxygen: 16 g/mol
# moles of oxygen = 30.06 g / 16 g/mol =1.87875

Proportions

1.87875  moles of Oxigen/ 1.252moles of iron = 1.50 /1

3moles of Oxygen: 1 mol of Iron

Empirical formula: FeO3

Molar mass of the empirical formula: 55.85 g/mol + 3(16g/mol) = 103.85 g/mol

Molar mass of the compound / molar mass of the empirical formula = 199.55 g/mol / 103.85 g/mol = 1.92

Round to 2.

Then the molecular formula is the empirical formula times 2.

Fe2O6
