Chur answerwould be B concentrated in the nucleus
Answer:
Cu
Explanation:
In the given reaction of the addition of copper to nitric acid,
Cu(s) + 4HNO3(aq) -> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
Cu or copper would be characterized as the reducing agent in this reaction. It is the chemical substance that is losing electrons and being oxidized due to this reduction/loss in this redox reaction as it is the metal that loses electrons by reacting with the non-metals.
There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit.
The first one is false the second one is the green house effect
H %= 100- (52.14 + 34. 73) equals 13.13 %
Assuming 100 g of this compound
Mass H= 13.13 g
Moles H= 13.13 g ÷ 1.008g/ moles= 13
Mass C= 52.14 g
Moles C= 52.14 g ÷ 12.011 g/ moles= 4
The empirical formula is C4H1302
