Since solubility decreases rapidly as the diver returns to the surface, the risk of having “the bends” is greater as the diver returns to the surface.
The solubility of a gas refers to the amount of the gas that dissolves in a liquid. Solubility of a gas is dependent on pressure. The greater the pressure, the higher the solubility of the gas and vice versa.
Pressure increases with depth as a diver moves down the sea. More pressure is exerted, the deeper the diver goes. This means that solubility of nitrogen in blood increases at a greater depth.
As the diver returns to the surface, the pressure decreases rapidly and the solubility of nitrogen also decreases suddenly making the risk of “the bends” to be greater as the diver returns to the surface.

Answer: The four 
hybridized orbitals on Sb makes up the sigma bonds between Sb and F in antimony(iii) fluoride ,
Explanation:
According to VESPR theory:
Number of electrons around the central atom : ![\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
V = number of valence electrons
N = number of neighboring atoms
C = charge on cation
A = charge on an anion
In antimony(III) fluoride ,
Antimony being central atom: V= 5,N =3,C=0,A=0
Number of electrons : ![\frac{1}{2}[V+N-C+A]=4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D%3D4)
Number of electrons around the central atom are 4 which means that molecule has four hybridized orbitals.
Answer:
It is necessary because Trans-cinnamic is a limiting reagent in the mixture reaction while Bromine is the excess reagent
Explanation:
It is necessary to maintain excess bromine in the reaction mixture because Bromine is the excess reagent in the reaction mixture and if it's quantity is less it would consume the limiting reagent ( Trans-cinnamic ) completely . hence Bromine should maintain excess quantity in the reaction mixture
Answer:
A
Explanation:
When a temperature increases particles tend to collide with each other often as they gain kinetic energy making them collide much more often and they'll collide with more energy due to the increase of kinetic energy
