Answer:
Gravity is normal...
Explanation:
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. So, theoretically speaking planets move or get pulled due to their huge amount of mass.
Answer:
2.5 moles of H2
Explanation:
First, let us write a balanced equation for the reaction of Hydrogen to produce water. This is shown below:
2H2 + O2 —> 2H2O
From the equation above,
2 moles of H2 produced 2 moles of H2O.
Therefore, 2.5 moles of H2 will produce 2.5 moles of H2O
Answer:
