The answer should be A. NW Hemisphere
Answer:
A. Strong Acid Strong Base
D. ... 100%
Explanation:
The reaction of hydrobromic acid and sodium cyanide is a strong acid-strong base reaction. In solution, sodium cyanide functions as a strong base and reacts violently with strong acids. For strong acid- strong base reaction, the extent of reaction is usually 100%.
The molecular reaction equation is
NaCN(aq) + HBr(aq) ---------> NaBr(aq) + HCN(aq)
Ionically:
H3O+(aq) + CN- (aq) ----------> HCN(aq) +H2O (l)
HCN(aq) is a weak acid.
Answer:
false
Explanation:
it happens in light-independent reactions
They contain both carbon and hydrogen :)
No. of moles in 134g of Mg, n=134/24 =5.58 moles
No. of atoms = n* Avogadro number
= 5.58 X 6.022 X 10^23
=33.60 X 10^23 atoms
