Answer:
Neon and Methane
Explanation:
Nitrogen and Oxygen made up way over half of the atmosphere so it's without a doubt, not those two. Precisely, Nitrogen makes up 78% of the atmosphere while oxygen makes up 21%
Answer:
The fire may grow bigger, depending on the gas.
Explanation:
If you expose more air to a small flame then it could grow larger because air keeps fire alive.
Answer:
50 g
Explanation:
d= m/v
rearranging the above equation
m = d x v
m = 2.5 g x 20 g/cm3
m = 50 g
Answer:
Experiment one.
You want to find out the absence of a certain mineral so you will take away the mg of nutrients.:
Answer:
Tetrahedral
Bent
Explanation:
A molecule in sp3 hybridization is ordinarily expected to exhibit tetrahedral electron domain geometry. This implies that it has four electron domains.
We were specifically informed in the question that two lone pairs are present. Remember that lone pairs distort the molecular geometry away from the expected geometry based on VSEPR theory.
Therefore, the bond angle of the molecule is <<109.5 degrees and its molecular geometry is bent (e.g water)
