B
Explanation:
Conifers live in cooler regions
Answer:
132g/mol
Explanation:
The problem here is to find the molar mass of the compound in g/mol
To solve this problem, we simply sum the atomic masses of the atoms in the compound:
(NH₄)₂ SO₄:
Atomic mass of N = 14g
Atomic mass of H = 1g
Atomic mass of S = 32g
Atomic mass of O = 16g
So;
Molar mass = 2[(14 + 4(1))] + 32 + 4(16) = 132g/mol
Answer:
Sample Response: Viscosity refers to a liquid’s resistance to flow. Liquids with a higher viscosity flow more slowly. In liquids that are more viscous, there is a stronger attraction between atoms.
Explanation:
it's the sample response so it's correct lol, I hope it helps.
The density will become less, this is because thing with less density float to the top when things with more density float to the bottom. It also becomes colder.
Sodium is in group 1 and so will form Na+. Selenium is in group XVI (6) and so will form Se2- . Thus, the compound formed, sodium selenide, will be Na2Se
