Answer:
Salt
Explanation:
salt particles make it harder for water particles to freeze back onto the ice
ice that is in contact with dissolved salt melts faster
Answer:
The new pressure is 3850 torr.
Explanation:
The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :

Here,



Let
is the new pressure. So using Boyle's law we get :

or

So, the new pressure is 3850 torr.
Answer:

Explanation:
2NO₂ ⇌ N₂O₄
E/mol·L⁻¹: 0.058 0.012
K_{\text{eq}} = \dfrac{\text{[N$_{2}$O$_{4}$]}}{\text{[NO$_{2}$]$^{2}$}} = \dfrac{0.012}{0.058^{2}} = \mathbf{3.6}
\\\\
\text{The $K_{\text{eq}}$ value would be $\boxed{\mathbf{3.6}}$}
Answer: About 0.20 grams of copper (II) is formed, and some aluminum is left in the reaction mixture
