Answer:
52.2g of KCl would be left
The mass of KCl will remain despite the solution is been heated
Explanation:
When you are heating a solution, just the solvent (In this case, water), will be evaporated and, in theory, the mass of KCl will remain despite the solution is been heated.
Now, the mass of KCl that you can obtain from 350mL of a 2.0M solution will be:
<em>Moles KCl:</em>
350mL = 0.350L * (2.0mol / L) = 0.700 moles
<em>Mass KCl -Molar mass: 74.55g/mol-:</em>
0.700mol * (74.55g/mol) = 52.2g of KCl would be left
Answer:
I wanna say c
Explanation:
It makes the most sense, because non-metals don't produce an electrical current, and therefore aren't conductors.
Answer:
The identity does not matter because the variables of Boyle's law do not identify the gas.
Explanation:
The ideal gas law confirms that 22.4 L equals 1 mol.
