The pressure that will be exerted if four sample of gas are placed in a single 3.5 container is calculated as below
if each gas occupies 675 mmhg
what about 4 gases in the sample
by cross multiplication
= 675 mm hg x 4/1 = 2.7 x10^3mmhg (answer D)
The chemical equation for the combustion of propane can be represented as,
1 mol propane requires 5 mol oxygen for complete reaction to produce 3 mol carbon dioxide and 4 mol water.
Mass of propane = 25.0 g
Mass of oxygen = 90.7 g
The total mass of reactants = 25.0 g + 90.7 g = 115.7 g
According to Law of conservation of mass, the total mass of reactants will be equal to the total mass of products formed in a chemical reaction.
Therefore, here the mass of water and carbon dioxide will be 115.7 g
Correct answer: a. 115.7 g

Answer:-
If an element has 3 or more valence electrons then the element belongs to p block of the periodic table. For p block elements the group number is found out by adding the number of electrons in valence shell + 10.
The reason for this is because in the middle of the periodic table there are the d block elements ranging from group 3 to group 12 a total of 10 groups in between elements having 2 valence electrons and 3 valence electrons
