In chemistry, the octet rule explains how atoms of different elements combine to form molecules. In a chemical formula, the octet rule strongly governs the number of atoms for each element in a molecule; for example, calcium fluoride is CaF2 because two fluorine atoms and one calcium satisfy the rule. Hope this helps
False, pepsin and hydrochloric acid
In
Methyl Amine the Nitrogen atom is attached to two Hydrogen Atoms and one Methyl (CH₃-) group. From
Lewis structure it is shown that the Nitrogen atom also contains a
lone pair of electron.
So,
According to
Valence Shell Electron Pair Repulsion (VSEPR)
Theory, those central atoms which have four electron pairs and all of them are bonding electron pairs gives
Tetrahedral Geometry.
Methylamine also contains four electron pairs, but out of four only
three are bonding pair electrons and
one lone pair electron. Now, due to presence of lone pair of electron (which has
greater repulsion effect than bonding electron pair) the bond angle between H-N-H will decrease from
109° to 107° and results in the formation of <span>
Trigonal Pyramidal geometry as shown below,</span>
Answer:
a) Equilibrium shifts in forward direction.
Explanation:
If pressure is increased, equilibrium shifts to the side with the fewer moles of gas.
There are 4 moles of gas in the reactants and 2 moles of gas in the products.
The equilibrium will shift in the forward direction towards the products.
Hope that helps.
