C.) addition polymerization
because there is an addition of ethene molecules but there are no bond being condensed
Because chemical energy is stored the chemical reaction takes place the stored chemical energy is released.
A : falling back to a it’s original lower state after being excited by fire.
Answer:
The correct answer is 0.033 M
Explanation:
We have a solution of NaClO with a concentration of 5%w/w:
5% w/w= 5 g NaClO/100 g solution
The first dilution is 10 ml of solution in 100 ml. That is a 1/10 dilution (10ml/100 ml= 1/10). That means we are diluting 10 times the solution. We can calculate the resulting concentration after this first dilution as follows:
5%w/w x 10 ml/100 ml = 5% w/w/10= 0.5%w/w
Then, we take 6 ml of 0.5% w/w solution and we add 6 ml of dye in a reaction vessel. The total volume of the solution in the reaction vessel is 6 ml + 6 ml= 12 ml, and we are diluting twice the solution because 6 ml/12 ml= 1/2. We can calculate the resulting concentration of the solution after this second dilution as follows:
0.5% w/w x 6 ml/12 ml= 0.5% w/w/2= 0.25%w/w
Finally, we need to convert the concentration from %w/w to M (mol solution/1L solution). For this, we assume a density of the solution close to the density of water (1.00 g/ml) and we use the molecular weight of NaClO (74.44 g/mol):
0.25 g NaClO/100 g solution x 1 mol NaClO/74.44 g x 1.00 g solution/1 ml x 100 ml/0.1 L= 0.033 mol/L
= 0.033 M
Answer:
a power plant that runs on oil
Explanation:
A generator a power plant that runs on oil uses non-renewable sources of energy to generate electricity.
Non - renewable energy is an energy source that cannot be replenished within a short period of time. It takes geologic time scales to form such energy sources.
Oil is a fossil fuel and a non-renewable source of energy.
As it is used, the reserve is being depleted.
