The total pressure in the container after the three gases are mixed is 6 atm and the partial pressure of He is 1 atm.
<h3>What is Dalton's Law of Partial Pressure ?</h3>
According to Dalton's Law of Partial Pressure , the pressure exerted by a mixture of gas is equal to the sum of the partial pressure of the gases in the mixture.
P(total) = p₁ +p₂+p₃+.....
As the volume of the containers are same and the
n = 1*5/RT for Helium
n = 2*5 /RT for Neon
n= 3*5/RT for Argon
Mole fraction = moles of the element/Total moles
Moles fraction of Helium is
= 1/6
Total Pressure in the container = 1 + 2 +3 = 6 atm
The partial pressure of Helium will be
=Mole fraction * Total pressure
=(1/6)*6 atm
= 1 atm , as the volume is same the temperature is same , the pressure will also be same.

Answer:
12.01 g
Explanation:
Molar mass is the number of grams of a substance per mole of it.
Molar masses of elements are actually already present in the periodic table. Looking at carbon (C) on a periodic table, you'll find that its molar mass is approximately 12.01 grams.
Answer:
No, it is not balanced.
The balanced equation is: Zn(OH)₂ + 2NaOH → Na₂ZnO₂ + 2H₂O.
Explanation:
- To balance the equation, you should apply the law of conservation of mass for the equations.
- The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).
- For the given equation: <em>Zn(OH)₂ + NaOH → Na₂ZnO₂ + H₂O.</em>
The no. of Na atoms in reactants side is 1 but in products side is 2.
The no. of H atoms in reactants side is 3 but in product side is 2.
<em>So, the equation is not balanced.</em>
<em></em>
- The balanced equation is:
<em>Zn(OH)₂ + 2NaOH → Na₂ZnO₂ + 2H₂O.</em>
<em></em>
- The no. of all atoms is the same in both of reactants and products side.
Zn (1), O (4), H (4), and Na (2).
