Here, the number of protons are different. As they have different atomic numbers, it would be: "Isobars"
Hope this helps!
Answer:
Z in chemistry means atomic number but I guess there is 'Zahl'
Answer:
Explanation:
The mass of an atom is dependent on its number of protons and neutrons. Electrons have mass, but are too light in comparison to protons and neutrons to contribute towards the overall mass. Their relative mass is about 1/1840 compared to 1 for protons and neutrons, and therefore are not counted in the mass.
Hope this helped!
Eg: 2H2 + O2 ➡ 2H2O
This shows that sum of reproducts = sum of products.
Therefore, mass is conserved.
I hope this helps you.
Answer:
Explanation:
Since temperature is to be maintained ; constant temperature and a such, the process is ISOTHERMAL
- to calculate mass of then gas = P1V/RT1
- m1 = 10 x 10^5 x 0.3 / 287 x 330
- similarly for m2 = P2V/RT2
- hence required mass = m1 - m2
b) Considering a well-insulated cylinder ;
Cp = 29J/molK
Temperature T2 = T1 [ P1/P2]^(1-γ)/γ
where γ = 1.4
plugging the values into the equation ; T2 = 171k
hence mass of the gas m1 = P1V/RT1
= 10 x 10^5 x 0.3/287 x 171
= 6.11kg
mass of m2 = P2V/RT2
= 10^5 x 0.3/287 x 171
= 0.611kg
hence required mass = m1 - m2
= 5.50kg
