In a chemical equation, the symbol that means “dissolved in water” is (aq).
Answer:
all atoms of the same chemical element have the same number of neutrons true or false ANSWER NO
Explanation:
Answer:-
(iv) (i) + (II)
Explanation:-
Hydrogen bonds Occur between Hydrogen and an element with high electronegativity like N or O.
DNA base pairs are arranged such that they are complimentary. Hence hydrogen bonding will occur between both the amide carbonyl and NH2 as well as the amide NH and Nitrogen of the cyclic C=N-C group.
Answer:
8kJ/mol
Explanation:
since the forward reaction is -8kJ/mol, the backward reaction has the same enthalphy but reversed
One of the industrial method for the production of hydrogen is the steam reforming process while oxygen is air separation.
<h3>
Industrial method of hydrogen preparation </h3>
One of the industrial method for the production of hydrogen is the steam reforming process also known catalytic steam–hydrocarbon process.
In catalytic steam–hydrocarbon process, gaseous or vaporized hydrocarbons are treated with steam at high pressure over a nickel catalyst at 650°–950° C to produce carbon oxides and hydrogen.
<h3>
Industrial method of oxygen preparation </h3>
One of the industrial method of oxygen production is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process.
