Answer: The smallest unit of matter.
Explanation:
Answer: The concentration of the weak acid in the sample is 0.1224 M
Explanation:
The balanced chemical reaction is :
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the concentration (in M) of the weak acid in the sample is 0.1224
Answer:
The air pressure in the ears increases
The volume of air in the ears increases
The change in volume causes discomfort
It takes time for the ears to dispell excess air past the ear drum.
Explanation:
As the plane engages in a steep incline into the atmosphere, the outside atmospheric pressure decreases with altitude. The air pressure in the ear, therefore, become greater than atmospheric pressure. The air volume in the ear therefore grows and pushes on the ear causing discomfort. As the air in the cabin pressurizes the discomfort eases away as pressure equalization is restored relative to the ear.
C. Chromosomes ive taken a quiz and it had the same question and i got it correct
Answer:
Dalton did not have the necessary instruments to see or otherwise experiment on individual atoms, he did not have any insight into whether they might have any internal structure.
Explanation:
So the answer is Dalton
