Answer:
0.375 moles of CaCO₃ are required
Explanation:
Given data:
Number of moles of sulfamic acid = 0.75 mol
Number of moles of calcium carbonate required = ?
Solution:
Chemical equation:
2H₃NSO₃ + CaCO₃ → Ca(SO₃NH₂)₂ + CO₂ + H₂O
Now we will compare the moles of H₃NSO₃ and CaCO₃ .
H₃NSO₃ : CaCO₃
2 : 1
0.75 : 1/2×0.75 = 0.375 mol
Thus, 0.375 moles of CaCO₃ are required.
Answer:
A book held high over a desk
Explanation:
Gravitational potential energy, or GPE, is like height energy. The higher up an object is placed, the more GPE it has. Gravitational potential energy is the potential of a certain mass relative to another due to gravity. In this case you have a book held high over a desk and therefore since it's higher up it's going to have more potential energy due to gravity, which is why it has gravitational potential energy. Therefore your answer is "a book held high over a desk".
