Answer:
The answer is rather simple, if you understand electron configurations: the shape of the periodic table mimics the filling of the subshells with electrons.
Explanation:
Answer:
Metabolism
Explanation:
The sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.
The answer would be C because I did the test and I got 1 question wrong and made an 90% .
Answer:
∆t(f) = 49.755C
Explanation:
Freezing point is defined as the point in which a liquid changes from liquid to solid state. Therefore, to calculate the freezing point of aqueous solution of propanol
∆t = k × I × m
Where k is cryscopic constant =
I = vant Hoff factor = 2
M = molar concentration = 12.25m
∆t (f) = 1.9 × 12.25 × 2 = 49.755C
Most likely the equation yields a new compound XY. This is a synthesis reaction. <span>Synthesis
reaction is a reaction where two or more substances combine to form a new
compound. It is a reaction which releases energy in the form of heat and
light. Therefore, it is an exothermic reaction.</span>
