Answer:
B. Mixing a solute and a solvent
Explanation:
Hello,
In this case, solutions are defined as liquid homogeneous mixtures formed when two substances having affinity are mixed. It is important to notice that the two substances are known as solute, which is added to other substance that is the solvent. Therefore, answer is B. Mixing a solute and a solvent.
Notice that when two insoluble substances are mixed no solution is formed. Furthermore, if two solutes together or a solute and a precipitate are mixed, no liquid homogeneous solution is formed, as commonly solutes are solid, nevertheless, when liquid, one should have to act as the solvent.
Best regards.
Answer:
0.16 atm
Explanation:
Let's look at the formula PV=nRT. First of all, T should be in kelvin, so let's add 273. Now solve for P so we get P = nRT/V.
Now let's plug these in...
P = (0.034 mol)(0.08206 L atm mol^-1 K^-1)(298 K)/5.1 L
After solving and rounding to sig figs we get 0.16 atm
Al (1s²2s²2p⁶3s²3p¹) - 3e⁻ → Al³⁺ (1s²2s²2p⁶)
3s²3p¹
Explanation:
Electrons are negatively charged. So it has a -3 charge.
