What is the formula of the missing product?
(1) CH3OH (3) H2O
(2) HCOOH (4) H2O2
Answer : The correct option is, (4)
Explanation :
Combustion reaction : It is a reaction in which a hydrocarbon react with the oxygen gas to produces carbon dioxide as water as a products.
The given incomplete equation are :
In this equation, we see that a hydrocarbon and oxygen gas are present on reactant side and carbon dioxide are present on product side but water molecules are missing on the product side. So, we are adding water on missing side.
The given complete equation will be :
Therefore, the formula missing on product is,
The reaction of sodium with bromide is sodium bromide. The balanced chemical equation is Na + Br → NaBr. In the reaction, only one mole of sodium is needed to react with one mole of bromine to produce one mole of sodium bromide.

Answer:
The partial pressure of nitrogen is 0.402 atm.
Explanation:
Given data:
Number of moles of helium = 1 mol
Number of moles of nitrogen = 2 mol
Total pressure of mixture = 0.60 atm
Partial pressure of nitrogen = ?
Solution:
First of all we will calculate the mole fraction of nitrogen.
mole fraction of nitrogen = moles of nitrogen / total number of moles
mole fraction of nitrogen = 2 mol / 3 mol = 0.67
Partial pressure of nitrogen:
P₁ = [ n₁ /n(t)] × Pt
P₁ = 0.67 × 0.60 atm
P₁ = 0.402 atm
To find the partial pressure of nitrogen in a mixture, calculate the mole fraction of nitrogen and multiply it by the total pressure of the mixture. In this case, the partial pressure of nitrogen is 0.40 atm.
The question is about determining the partial pressure of nitrogen in a mixture of helium and nitrogen based on Dalton's Law of Partial Pressures. First, we find the mole fraction of nitrogen, which is the ratio of moles of nitrogen to the total moles in the mixture. In this scenario, the mole fraction (XN2) is 2 moles of nitrogen divided by the total moles (1 mole of helium + 2 moles of nitrogen), which equals 2/3.
Then we use Dalton's Law, which states that the partial pressure of nitrogen (PN2) can be found by multiplying the mole fraction by the total pressure of the mixture. Therefore, the partial pressure of nitrogen is 0.60 atm (total pressure) multiplied by 2/3 (mole fraction of nitrogen), yielding a partial pressure for nitrogen of 0.40 atm.
