Chemical equilibrium is reach when the concentrations of the product and reactants will no longer change with time. this does not mean that there is no change in concentration, only the net change is zero. the forward rate of reaction is now equal to backward rate of reaction.
Formula 1!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Nuclear Fission.
Explanation:
This happens when a high-energy particle collides with a radioisotope, which splits into 2 daughter nuclei, several neutrons (which can collide with more radioisotopes to cause a chain reaction); and a lot of energy. That's why nuclear power plants are so good.
Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .
Answer:
C. 2-methylpropane
Explanation:
There are rules guiding the naming of hydrocarbons. Some of the rules are:
1.) The longest continuous chain is the parent chain:
The longest chain here is made up of 3-carbon atoms which is a propane compound
2.)The carbon atoms are numbered in the parent chain to indicate where branching or substitution takes place.
Here, it is in the second carbon atom in propane.
The branched group is methyl- which is a methane molecule that has lost a hydrogen atom.
This makes ths name of the compound to be:
2-methylpropane
