Molar mass of MgCO3 is 84.313 g/mol
You can calculate this from data on the periodic table:
Molar mass Mg = 24.305g/mol
molar mass C = 12.011g/mol
molar mass O = 15.999g/mol mass 3 mol = 47.997g
Total = 84.313g/mol
Mass to be used in 1.2L of 1.5M solution = 84.313g * 1.2L * 1.5mol /L = 151.763g
I have not taken significant figures into account
The balanced equation you provide is not necessary in this calculation
Answer:
d. IF3
Explanation:
The Octet rule posits that atoms gain, atom lose, or share electrons in order to have a full valence shell of 8 electrons. This statement occurs when atoms also combine to form molecules until they attain or share eight valence electrons either by losing or gaining eletrons.
From the given options, a valid Lewis structure that cannot be drawn without violating the octet rule is IF3
Answer:
He assumed wrongly
Explanation:
It happened this way because the person assumed wrongly.
Most other compounds have the same physical appearance as water especially when in liquid form.
- This can be a very tricky one in the laboratory.
- The sense of taste is not the best way to fathom what a particular compound is made up of.
- This is the reason why this student or person faced this sort of problem.
- Water has different properties that can be tested for using simple techniques in the laboratory.
Answer:
The liver
Explanation:
The liver -
In human beings the location of liver is just in the upper right portion of the abdomen , exactly below the diaphragm .
Liver is present in specifically vertebrates , and is responsible for various metabolism , like producing hormones , decomposition of the red blood cells , regulating the storage of glycogen and the synthesis of proteins .
Liver is the main site for the process of gluconeogenesis , amino acid catabolism .
Liver is the very organ , that has full urea cycle .
Hence , from the given information of the question ,
The correct term is the liver .
