CaCO3 + 2 HCl ---------> CaCl2 + H2O + CO2
This is the balanced chemical equation
Hope this helps
Answer:
the same thing that happens to United states will happen to other regions
Explanation:
125 Kelvin turns into -146 C
Answer:
11.6g of NH₃(g) have to react
Explanation:
For the reaction:
4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(g) ΔH = -905kJ
<em>4 moles of ammonia produce 905kJ</em>
Thus, if you want to produce 154kJ of energy you need:
154kJ × (4 mol NH₃ / 905kJ) = <em>0.681moles of NH₃. </em>In mass -Molar mass ammonia is 17.031g/mol-
0.681mol NH₃ × (17.031g / mol) = <em>11.6g of NH₃(g) have to react</em>
pretty sure it's both are physical changes.
