Explanation:
all about density and mass and size of the molecules in a liquid and how close they are packed together
Answer:
Group 13
Explanation:
You know X has 3 valence electrons, as oxygen has a subscript of 3. This means X has an ionic charge of +3. Group 13 consists mainly of metalloids but it also has metals such as aluminum, which has a +3 charge. If you use aluminum as an example, you know that when combined with oxygen, it forms Al2O3. Group 12 has transition metals that don't have +3 ionic charges, group 14 has metalloids, metals that don't have ionic charges of +3, and nonmetals, and group 2 has metals with ionic charges of +2. Group 13 is the answer.
Answer:
mass of the planet and its distance from other objects
Explanation:
The formula that we will be using is:
total salt / total solution = .10
Let a be the ml of the first solution
And let b be the ml of the second solution
.25a + .05b / a + b = .10
Also:
a + b = 1400
a = 1400 - b
So substitute:
.25 x (1400 - b) + .05b / 1400 = .10
350 - .25b + 0.05b/ 1400 = .10
350 - .2b / 1400 = .10
350 - .2b = .10 x 1400
.2b = 350 - 140
.2b = 210
b = 1050
a = 1400 - b
a = 1400 - 1050
= 350 mL
