CO2 is not polar as in this case the same types of molecules
are pulling in the same as well as opposite direction. CH4 is also not polar as
there is no imbalance in the charge of the molecules. CBr4 is also not polar
because in this case also no imbalance in the molecular charges can be seen.
CHBr3 is a bit polar in nature because it has different kind of charges at its
opposite ends. S among the all 4 options CHBr3 is polar.
Answer:
The value of the equilibrium constant (K) remains the same.
Explanation:
A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.
At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.
Answer:
4.816x10²⁴atoms
Explanation:
the number of moles of oxygen is 8
let x be number of oxygen atoms
recall that 1 mole=6.02x10^23 atoms
therefore, 8 moles =x
cross multiply
8 x 6.02 x 10^23 = x
x = 4.816 x 10²⁴atoms
Is 320 g per 100 g of water.
Answer:
Heat
Explanation:
Energy exchange occurs when two systems exchange energy between them, or a system exchange energy with its surroundings. This phenomenon can happen in two ways: heat or work.
The heat is the exchange of energy caused by the difference in temperature. So, when the systems lose heat, its temperature decreases, and when it gains heat, its temperature increases.
The work is the energy exchange caused by the difference in volume and pressure. When a gas expands, its volumes increase, and it does work to its surroundings. When it compresses, its volumes decrease and it suffers work from its surroundings.
So, when the wax melt, the temperature of it must have increased, and it has gained heat. The energy exchange as heat.
