Explanation:
The law of conservation of mass states that mass is conserved which also means that it cannot be created or destroyed within the isolated system.
We can add the mass of the reactant and can be equal to the mass of the product. But in some cases, it will not work like:
If reactants are not in the mole ratio, there will be a limiting reagent.
If a gas is one of reactants or products.
Radioactive decay and nuclear reactions(fission or fusion).
Its the last answer #""_53∧131"I" #
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
<h2>The equation that agrees with the ideal gas law: None of it </h2>
Explanation:
None , of the given equation goes with the ideal gas law .
Ideal gas law
It is the law that gives the relationship between P,V,T and number of moles .
Ideal gas equation
It is the law that is formed by combining Boyle's law , charle's law ,Avgadro's law that is :
P ∝ 1/v
V∝T
V∝n
combining all, we get
PV=nRT
where R is a gas constant .
This is an ideal gas equation ,
- The first option given : V₁/T₁=V₂/T₂
- The second option : V₁n₁=V₂n₂
- The third equation : P₁n₁=P₂n₂
- The fourth option : P₁/T₁=P₂/T₂
none ,of it specifies because ideal gas equation relation is :
P₁V₁/T₁=P₂V₂/T₂ is an ideal gas equation
