The fusion reaction in the sun is a combination of hydrogen atoms fusing to create helium. The fusion reaction in larger stars involve much heavier elements like oxygen and iron. In supernovas, often elements like gold are produced
Answer:180°
Explanation:
According to VSEPR theory, if the valence shell of the ceteral atom in a molecule contains only two valence electron pairs, the valence electron pairs will arrange themselves along a straight line, forming a bond angle of 180°

We would need 0.037 mol. We know that because of a formula we can use and some data from the problem. The formula would be:
n= Number of heat in kj x 2 moles
--------------------------------------
5460 kJ
The number of Kj of heat is provided(100 kJ). The standard enthalpy of combustion is -5460.0 kj. so we multiply 100 kj and 2 moles and then we divide on 5460 kj and the answer is 0.037 moles.
