Genes are segments of DNA, and DNA is of course a part of fiber from your parents, so when you get that DNA, you usually inherit a few traits or hobbies from them
Firstly calculating number of moles of hcl disssolved. The answer would be in the pic above. Concentration of hydrogen ions can be calculated by using that mole amount dividing by 3litres of solution to get 0.003196. Hence the ph of solution will be -log10(h+ concentration) which is equal to 2.495
The balanced chemical reaction is expressed as:
3HCl + Al(OH)3 = AlCl3 + 3H2O
We are given the amount of aluminum hydroxide to be used up in the reaction. This value will be the starting point for the calculations. We calculate as follows:
1.55 g Al(OH)3 ( 1 mol Al(OH)3 / 78 g Al(OH)3 )( 3 mol HCl / 1 mol Al(OH)3 ) = 0.06 mol HCl
Volume = 0.06 mol HCl / 0.120 mol HCl/ L solution = 0.50 L solution
Answer:
The three-step synthesis of trans-2-pentene from acetylene is as follows.
<u>Step -1:</u> Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.
<u>Step -2:</u> Formation terminal alkyne to nonterminal alkynes.
<u>Step -3:</u> Formation of trans-pent - 2-pent-ene by reduction.
Explanation:
Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.
The chemical reaction of each step of chemical reactions is as follows.
D. It slows down
It slows down because the water keeps its from sinking
