No, because the sun stays in the same exact place all of the time
Answer:
A. Energy is released
Explanation:
Energy is only released when chemical bonds are formed.
Answer: 
Explanation:
- The atomic mass of nitrogen is 14.0067 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
This means the molecular mass of nitrogen dioxide is 
g/mol.
Dividing this molecular mass of the compound we need to find, we get that
.
So, the final answer is 
A: to determine the traits of the cell
Answer:
1.5 moles of CO₂ are produced
Explanation:
Based on the chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O<em> -The reaction of the question is wrong-</em>
5 moles of oxygen reacts per mole of propane, C₃H₈, to produce 3 moles of CO₂ and 4 moles of water.
If 2.5 moles of oxygen react and, 5 moles of oxygen produce 3 moles of CO₂, moles of CO₂ produced are:
2.5 moles O₂ * (3 moles CO₂ / 5 moles O₂) =
<h3>1.5 moles of CO₂ are produced</h3>
