Answer:
The correct answer is AMP+H2O→ Adenosine + pi
Explanation:
The above reaction is least energetic because there is no phosphoanhydride bond present with adenosine mono phosphate.Phospho anhydride bond is an energy rich bond.
As a result hydrolysis of AMP generates very little amount of energy in comparison to the hydrolysis of ATP and ADP.
The wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down.
Answer:
Explanation:
Oxidation no is equal to charge on each atomic ion. If it is increased , element is oxidised and if it is decreased , element is reduced .
2AgCl+Zn⟶2Ag+ZnCl2
Zinc is oxidised , Ag is reduced .
Ag⁺ converts to Ag . ( oxidation number is reduced ) so Ag is reduced.
Zn converts to Zn⁺² ( oxidation number is increased ) so Zn is oxidised .
4NH₃+3O₂⟶2N₂+6H₂O
oxidation number of nitrogen in ammonia is - 3
oxidation no of nitrogen in nitrogen is zero.
Oxidation no of nitrogen is increased so it is oxidised.
oxidation no of oxygen is zero in oxygen and its oxidation no in water is -2 . So oxidation no is reduced so oxidation is reduced.
Fe₂O₃+2Al⟶Al₂O₃+2Fe
oxidation no of Fe in Fe₂O₃ is + 3 and it is zero in Fe so iron is reduced.
oxidation no of Al in Al is zero and it is +3 in Al₂O₃ so it is oxidised .
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We calculate as follows:
0.180 mol Br2 ( </span>6.022 x 10^23 molecules / mole ) = 1.084x10^23 molecules Br2
This question could be answered easily if the results of the abundance of the other elements are given. You will just have to subtract the sum of all their abundances to 100. Since it's not given, the solution would just be:
Na = 23 g/mol* 1 = 23 g
H = 1 g/mol * 1 = 1 g
C = 12 g/mol * 1 = 12 g
O = 16 g/mol * 3 = 48 g
Total = 84 g
% O = 48/84 * 100 = <em>57.14%</em>
