<span>A. Salt lowers the freezing point of water, which makes the melted snow on the road less likely to form ice.</span>
The correct answer is D because the the rest will have different answers depending on the person you ask. D can be proven with facts by research
The mitosis is the cell division so it both B and C
Answer:
H₂(g) + Cl₂(g) → 2HCl(g) + 185kJ
Explanation:
In a chemical reaction, enthalpy of reaction ΔH is a thermodynamic constant that gives information if the reaction is exothermic (Produce heat if reacts) or endothermic (Consume heat if reacts).
In the reaction:
H₂(g) + Cl₂(g) → 2HCl(g) ΔH = -185kJ
As ΔH <0, the reaction is exothermic, that means, <em>produce heat</em>, writing a balanced thermochemical equation:
<em>H₂(g) + Cl₂(g) → 2HCl(g) + 185kJ</em>
<em></em>
The enthalpy is as a product beacause an exothermic reaction produces heat.
