As molecular mass increases, van der Waals interactions between molecules also increase, because numbers of electrons in the molecules.
Iodine (I) has greatest atomic number, so the number of electrons.
Hydrogen fluoride is exception, because hydrogen bonding between molecules.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
Answer:
The concentration of the copper(II) sulfate solution is 0.99 M
Explanation:
Step 1: Data given
Mass of copper(II) sulfate = 79 grams
Volume of the flask = 500 mL
Molar mass copper(II) sulfate = 159.61 g/mol
Step 2: Calculate moles copper(II) sulfate
Moles CuSO4 = Mass CuSO4 / molar mass CuSO4
Moles CuSO4 = 79.0 grams / 159.61 g/mol
Moles CuSO4 = 0.495 moles
Step 3: Calculate concentration
Concentration CuSO4 = moles / volume
Concentration CuSO4 = 0.495 moles / 0.5 L
Concentration = 0.99 M
The concentration of the copper(II) sulfate solution is 0.99 M
Answer: Yes fertilizers do make plants grow faster but the three combined water, sunlight, and fertilizer they grow much faster.
Answer: 6.65 bullfrogs per square
kilometer
Explanation:
The formula to calculate the population density will be:
= N/A
where,
N = total population = 452
A = land area = 68km²
Therefore, population density will be:
= N/A
= 452/68
= 6.65 bullfrogs per square
kilometer
Answer:
it depends on how you use action Because action means you are doing something and maybe action like reaction or something like a feeling if a bomb occurs that is the action.
