Explanation:
<span> If the temperature of the liquid is increased, then more sugar will dissolve, because warm solutions hold more solute than cold solutions.</span>
False, as pressure increases, temperature increases, given that other factors stay the same.
To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Cr3+ and O2-, you will get the neutral compound to be Cr₂O₃.
The proportion these ions combine in is 2 to 3. 2 ions of Cr3+ and 3 ions of O2-
Your answer is D) 2:3
D=mass/volume
1st sample: D=41.40g/4.5mL
D=9.2 g/mL
2nd sample: D=37.22g/4.3mL
D=8.66 g/mL
3rd sample: D=43.46g/4.8mL
D=9.05 g/mL
Average Density: 9.2+8.66+9.05=26.91
Answer: 26.91/3=8.97 g/mL
