Question 1
Dalton's Law Formula:
Protal = P7 + P2 + P3...
A closed beaker contains a mixutre of gases. Their partial pressures are:
Gas A = 2 atm
Gas B = 1 atm
Gas B = 4 atm
What is the total pressure of the gas mixture?

7 atm

Explanation:

According to Dalton's Law, the total pressure is the sum of all the individual gas pressures

Hence, Ptotal = P1 + P2 + P3

Since, Gas A = 2 atm

Gas B = 1 atm

Gas B = 4 atm

Ptotal = (2 + 1 + 4) atm

Ptotal= 7 atm

Thus, the total pressure of the gas mixture is 7 atmosphere.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
