The way its structured is they're layered on top of each other and because of that it has a much faster charge rate
Answer : The amount of heat released would be, (3) 811.68 kcal
Explanation : Given,
Moles of carbon monoxide = 12.0 mole
Enthalpy change = -135.28 kcal
The given balanced chemical reaction is,
From the balanced chemical reaction we conclude that,
As, 2 moles of carbon monoxide react to release heat = 135.28 kcal
So, 12.0 moles of carbon monoxide react to release heat = 
Thus, the amount of heat released would be, 811.68 kcal
Answer:
Reactions, 2, 3 and 5 make precipitates
Explanation:
1. The halogens always make aqueous salts with elements from group 1
2. Phosphate anion can make insoluble salts, the same as carbonate.
3. Nitrate anion always make aqueous salts
4. Sulfate anion makes aqueous salts except with Ag⁺, Pb⁺² and group 2
1. KI(aq) + NaCl(aq) → KCl(aq) + NaI(aq)
2. 2Na₃PO₄ (aq) + 3CoCl₂(aq) → 6NaCl(aq) + Co₃(PO₄)₂(s) ↓
3. Na₂CO₃ (aq) + CuCl₂ (aq) → 2NaCl (aq) + CuCO₃ (s) ↓
4. 2LiNO₃ (aq) + Na₂SO₄ (aq) → Li₂SO₄ (aq) + 2NaNO₃(aq)
5. CrCl₂ (aq) + Li₂CO₃ (aq) → 2LiCl (aq) + Cr₂(CO₃)₂ (s) ↓
The two liquids made a new substance.
<h3>What is a physical and chemical change?</h3>
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
A chemical change occurs when some substances are transformed into different substances, with different nature and properties. In this case when both liquids are mixed a solid is formed. This is an example of a change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture which is called a chemical change.
Hence, option D is correct.
