Answer:
CaCl₂(s) ⟶ Ca²⁺(aq) + 2Cl⁻(aq)
Explanation:
When the calcium chloride dissolves. the calcium and chloride ions leave the surface of the solid and go into solution as hydrated ions.
Answer: Avogadro's Law
Explanation: It states that the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature of the gas.
The electrical conductivity of a solution is the measure of the solution's ability to allow current to pass through it. This property is attributed to the amount of ions that are present in the solution. So, the answer to this item is IONS which are the positively or negatively charged particles.
Answer:
The equilibrium will shift to produce less ammonia
Explanation:
According to Le Chatelier's principle, the reaction will try to oppose anything that is done on it, if it was at equilibrium.
When the concentration of H2 is decreased, you are decreasing the concentration of hydrogen so the reaction tries to increase the concentration of hydrogen by breaking down the ammonia on the products side. This will decrease the output of ammonia
Answer:
Combustion reaction
General Formulas and Concepts:
<u>Chemistry</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define</u>
2C₂H₂ + 5O₂ → 2H₂O + 4CO₂
<u>Step 2: Identify</u>
Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction.
We also see from the RxN that is is a double replacement reaction.
