Answer:
The correct answer is D) hydration
Answer:
Hg2^2+(aq) + 2Cl^-(aq) —> Hg2Cl2(s)
Explanation:
The balanced equation for the reaction is given below:
2NaCl(aq) + Hg2(NO3)2(aq) —> 2NaNO3(aq) + Hg2Cl2(s)
Considering the states of each compound in the reaction, we can see that Hg2Cl2 is in solid form meaning it will precipitate out of the solution
In solution the following occurs:
NaCl —> Na+(aq) + Cl-(aq)
Hg2(NO3)2 —> Hg2^2+(aq) + 2NO3^-(aq)
Combining the two equation together, a balanced double displacement reaction occurs as shown below:
2Na+(aq) + 2Cl-(aq) + Hg2^2+(aq) + 2NO3^-(aq) —> 2Na+2NO3^-(aq) + Hg2^2+2Cl-(s)
From the above we can thus right the insoluble precipitate as
Hg2^2+(aq) + 2Cl^-(aq) —> Hg2Cl2(s)
Answer:
Terpene
Explanation:
They generally have strong characteristic odours. Specific Terpenes used in cleaning are a-pinene, d-limonene, and turpentine, which is a mixture of terpenes.
They are organic solvents.
I'm pretty sure a physical change because it's affecting the form of the chemical substance, but not its chemical composition
