Just the number 2 to get the cofficients
Answer: M = 22/ (i x28.948)
Explanation:
Pi = osmotic pressure = 22atm
T = Temperature = 353K
M = Molarity = ?
R = gas constant = 0.082atm.L/mol/K
i = van’t Hoff factor
Pi = iMRT
M= Pi /(iRT) = 22 / ( i x 0.082 x 353)
M = 22/ (i x28.948)
Solution: Change in state of matter is a physical change because of the physical condition and appearance changes but not the chemical composition.
Answer:
Coefficient in front of the
in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side,
must be multiplied by 6 and
by 4
Left side,
is multiplied by 5 and
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the
in the balanced equation - 4</u>
