Answer:
Fossils, Glaciers, Coastlines.
Explanation:
Evidence of plate tectonic theory are fossils, fossils of the same species were found oceans apart. also glaciers evidence of glaciers were found in places with warm climates. coastlines coastlines look like they fit in a puzzle.
Answer:
Mass = 26.50 g
Explanation:
Given data:
Mass of sodium carbonate = ?
Molarity of solution = 0.25 M
Volume of solution = 1.00 L
Solution:
Molarity = number of moles / volume in litter
0.25 M = number of moles / 1.00 L
Number of moles = 0.25 M × 1.00 L
Number of moles = 0.25 mol
Mass:
Mass = number of moles × molar mass
Mass = 0.25 mol × 106 g/mol
Mass = 26.50 g
I think that the answer could be A. X and Y
Answer:
0.2615 g
Explanation:
Given that mass of the body = 120 lb
The conversion of lb to g is shown below as:-
1 lb = 454 g
So, 120 lb = 120*454 g = 54480 g
The substance is of the human body
So, Mass of that substance in the body of mass 54480 g is:-
<u>0.2615 g of that substance would be found in the body of a person weighing 120 lb.</u>
It doesn't obey the octet rule.
