Answer:
D. The stronger the forces, the more heat that must be added to boil
the liquid
Explanation:
The intermolecular forces hold the molecules together and so require energy to break them. When a substance changes states, it's not the atoms that separate from other atoms, it's molecules separating from molecules. The stronger the intermolecular forces, the more energy is required to break the intermolecular forces
Answer: the original volume was 0.98L
Explanation:
V1 =?
T1 = 22k
V2 = 3.8L
T2 = 85k
V1 /T1 = V2 /T2
VI/22 = 3.8/85
V1 = 22 x (3.8/85)
V1 = 0.98L
Answer:
phone, microwave, internet box
Answer:
3 valence electrons
Explanation:
Because aluminum has three, that means three fluorines can bond. The make the formula AlF3, also known as aluminum trifluoride. Each of the fluorine atoms gets an electron to fill their shell, and the aluminum loses three, giving it a filled shell too (remember, aluminum has three extra electrons).
The answer would be using proportions 151/x=166/0.532, then you solve for x. The answer would be <span>0.483927711, but then you have to round it and get approximately 0.484 L. Hope this helps! Happy Studying!</span>
