Answer:
The correct answer is : 'the concatenation of NO will increase'.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where increase in temperature occurs.
As, this is an endothermic reaction, increasing temperature will add more heat to the system which move equilibrium in the forward reaction with decrease in temperature. Hence, the equilibrium will shift in the right direction.
So, the concatenation of NO will increase.
A physical change has occured, Boiling water is a physical change not a chemical one, now if you're talking about the electric current, that had not changes either. it may rearrange the molecules, but it does not change the fundamental properties of the substance.
Answer:
No
Explanation:
Let us examine this problem carefully:
Given compound is N₂O
Molecular mass = 88g
Now,
The empirical formula is the simplest formula of a compound.
The molecular formula is the true formula of the compound that shows that actual ratios of the atoms in a compound.
To find if they both have the same molecular and empirical formula, they must have the same molecular mass.
For N₂O;
Molecular mass = 2(14) + 16 = 44g/mole
But the true and given molecular formula of the compound is 88g/mole
This shows that the compound given is the empirical formula of the compound.
Molecular formula:
molecular mass of empirical formula x n = molecular mass of molecular formula
n = 
= 2
Molecular formula of compound = 2(N₂O) = N₄O₂
Therefore the empirical and molecular formulas are not the same
The Formula of Acetone is
To find the Mass Molar of a compound, you add the Atomic weights of it's atoms.
If you check the Periodic table:
Atomic Weight of Carbone C: 12.0107
Atomic Weight of Hydrogen: 1.00794
Atomic Weight of Oxygen: 15.9994
So, you got:
Total Atomic Weight of Carbone in Acetone: 12.0107 * 3 = 36.0321
Total Atomic Weight of Hydrogen in Acetone: 1.00794 * 6 = 6.04764
Total Atomic Weight of Oxygen in Acetone = 15.9994 * 1 = 15.9994
Now, you add this numbers
36.0321 + 6.04764 + 15.9994 = 58.07914
So, the Molar Mass of Acetone is 58.09714 g/mol
Hope this Helps :D
Answer:
All the elements of a group have similar chemical properties because they have same no. of valence electrons in their outermost shell.
All the elements of a period have different chemical properties because they have different no. of valence electrons in their atoms.
