Rutherford is the man responsible :)
1.A law is an observation; a theory is the explanation of that observation.
2.A theory requires experimentation under various conditions. A law has no such requirements.
3.A theory may become obsolete with time. This is not the case with a law.
4.A theory can be replaced by another better theory; however, this never happens with a law.
5.A theory may be strong or weak according to the amount of evidence available. A law is a universally observable fact.
Hope this helps:)

Answer:
The total pressure will be the sum of the partial pressure of these three gases.
Explanation:
According to Dalton law of partial pressure,
The total pressure exerted by mixture of gases is equal to the sum of partial pressure of the individual gas.
This expression can be written as,
P(total) = P₁ + P₂ + P₃ + ...... Pₙ
For example:
If the pressure of A is 2 atm and Partial pressure of B is 4 atm the total pressure will be,
P(total) = P₁ + P₂
P(total) = 2 atm + 4atm
P(total) = 6 atm
when third gas is added which exert the partial pressure of 4 atm,
Then total pressure will becomes,
P(total) = P₁ + P₂ + P₃
P(total) = 2 atm + 4atm + 4 atm
P(total) = 10 atm
Answer:
The answer is 13.
Explanation:
In an element, proton number is also define as atomic number. So if the element has 13 protons, it's atomic number will be 13.
