Answer:
Its pressure will be 0.54 atm at 100 K.
Explanation:
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
Gay-Lussac's law can be expressed mathematically as the quotient between pressure and temperature equal to a constant:

Studying two different states, an initial state 1 and a final state 2, it is satisfied:

In this case:
- P1= 1.75 atm
- T1= 50 °C= 323 K (being 0 C=273 K)
- P2= ?
- T2= 100 K
Replacing:

Solving:

P2= 0.54 atm
<u><em>Its pressure will be 0.54 atm at 100 K.</em></u>
Answer:
Hydrogen
Explanation:
This may be wrong but I can't really tell because of how you have written the question
It is either D or B
Hope I helped
Answer:
Ratio is 1:1 ; they have same number of molecules.
Explanation:
One mole of any compound have same number of molecules, irrespective of their chemistry and composition, i.e. 6.022x10^23 . This number is known as Avogadro's Number.
So the beaker with one mole of water contains = 6.022x10^23 molecules ;
and beaker with one mole of Hydrogen chloride = 6.022x10^23 molecules.
The comparative ratio is 1:1.
