Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun.


But this tilt changes. During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees.

How many moles of h2o are produced when using 7 moles of h2
Olenka [21]
1) Write the balaced chemical equation:

H2 + 2O2 → 2H2O

2) Infere the molar ratios:

1 mol H2 : 2 mol of water

3) Make the calculus as the direct proportion relation:

[2 mol H2O] / [1 mol H2] * 7 mol H2 = 14 mol H2

As you see you produce the double number of moles of H2O than number of moles of H2 used.

Answer: 14 moles

D. The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced. The conservation of the mass is a fundamental law of chemistry and physics. It indicates not only that during any experiment, including if it involves a chemical transformation, the mass is conserved, but also that the number of elements of each chemical species is conserved. Like any law of conservation it is expressed by a conservation equation.
