Answer:
The volume of the balloon would be 374 L.
Explanation:
Initially, He occuplies a volume of 17.0 L (V₁) at a pressure of 22.0 atm (P₁). If pressure decreases to 1.00 atm (P₂), volume is expected to increase. Assuming ideal behavior of the gas and constant temperature, we can calculate the final volume (V₂) using Boyle's Law.

Answer:
Compound D is CH3OPO3 is the best answer
Explanation:
Given :
Number of molecules of
.
To Find :
How many moles are in given number of molecules.
Solution :
We know, in 1 moles of any element/compound contains
at atoms/molecules.
So, number of moles in
molecules are :

Therefore, number of moles are 8.97 .
A indicator is a weak organic acid or a base which has shows different colors in acidic and basic mediums. The color change occurs when the weak acidic or basic indicator dissociates to give its respective conjugate base or conjugate acid.
Therefore the correct option would be Indicators are weak acids or bases.
