Answer:

Endothermic

Explanation:

An endothermic reaction is one in which energy is absorbed while an exothermic reaction is one in which energy is given out(evolved).

If we look at the reaction as written; 3C(graphite) + 3H2(g) + 88kcal -------> C3H8(g), we will notice that;

i) 88kcal of energy had to be absorbed for the reaction to occur

ii) The enthalpy change for the reaction is positive.

Since energy must be taken in to drive the forward reaction, then the reaction is endothermic as written.

What is carbonic acid and how does it affect rock?

Vadim26 [7]

<span>Carbonic acid is a chemical compound with the chemical formula H₂CO₃. It is also a name sometimes given to solutions of carbon dioxide as it contains water. It affects the rock by a process. When water meets carbon-dioxide in the air, a weak solution occurs called "CARBONIC ACID" and when it meets the crack of the rock, it diffuses and it ti dissolve with it. HOPED THIS HELPS YOU :)</span>

SpyIntel [72]

Answer:

2.94 g of water are produced by this decomposition

Explanation:

We need to determine the reaction to solve this problem:

The reactant is the ammonium perchlorate

The products are N₂, Cl₂, O₂ and H₂O

The reaction is: 2NH₄ClO₄ → N₂ + Cl₂ + 2O₂ + 4H₂O

We convert the mass of the reactant to moles:

9.6 g . 1 mol / 117.45 g = 0.0817 moles

Ratio is 2:4. Let's make a rule of three:

2 moles of perchlorate produce 4 moles of water.

Then, 0.0817 moles of perchlorate will produce (0.0817 . 4)/2 = 0.163 moles

We convert the moles of produced water, to mass (g)

0.613 mol . 18 g / 1mol = 2.94 g
