Answer:
The total pressure P = 1.642 atm
Explanation:
From the dalton's law
Total pressure of the mixture is
----- (1)
atm
atm

n = 0.24 mole
R =

T = 41 °c = 314 K

= 0.634 atm
From equation (1)
P = 0.419 + 0.589 + 0.634
P = 1.642 atm
Thus the total pressure P = 1.642 atm
A dibasic acid is an acid that has two oxygen ions to donate to a base in an
acid-base reaction.
Therefore, a dibasic molecule has two replaceable hydrogen atoms.
The cell divides to get 2 new cells. If you may have learned, sex cells can only divide four times. in a female egg cell, only one cell out of those can make a kid. In a male, all four cells are ready to make babies.
Hope this helps :)
Answer:
Option C. 200mL
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2NaOH + H2SO4 –> Na2SO4 + 2H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 2
The following data were obtained from the question:
Molarity of the base (Mb) = 1M
Volume of the base (Vb) =..?
Molarity of the acid (Ma) = 1M
Volume of the acid (Va) = 100mL
The volume of the base needed can be obtained as follow:
MaVa/MbVb = nA/nB
1 x 100 /1 xVb = 1/2
Cross multiply to express in linear form
Vb = 1 x 100 x 2
Vb = 200mL
Therefore, the volume of the base needed for the reaction is 200mL
