The reaction that describe an acid an acid- base neutralization reaction is
Be(OH)2 + H2SO4 = BeSO4 +2 H2O
Neutralization reaction involve an acid and a base reaction whereby the acid neutralization the base. for the reaction above Be(OH)2 is the base while H2SO4 is the acid thus H2SO4 neutralizes Be(OH)2 to form BeSO4 and H2O

Answer:
"Urban area is used for the buildings, industries etc, whereas the rural areas are used for cultivation, forest cover etc."
Explanation:
When we talk about the urban land they are mostly covered with buildings, industries, roads and apartments and also the municipal structures. But when we talk about the rural land it has less dense population with forest cover, agricultural lands, rangeland and also different land cover type. In the urban areas the population density is very high. Those areas that located in the outskirt of the town are the rural areas.
Answer:
1(a) N = 3
(b) N = 0
(c) N = 5
(d) N = -2
(2) Molecular formula for benzene is C6H6
Explanation:
1(a) N02 1-
N + (2×-2) = -1
N-4 = -1
N = -1+4 = 3
(b) N2
2(N) = 0
N = 0/2 = 0
(c) NO2Cl
N + ( 2×-2) + (-1) = 0
N - 4 - 1 = 0
N - 5 = 0
N = 0+5 = 5
(d) N2H4
2(N) + (4×1) = 0
2N + 4 = 0
2N = 0 - 4 = -4
N = -4/2 = -2
(2) Molcular mass of benzene = 78g/mole = (6×12g of carbon) + (6×1g of hydrogen) = 72+6 = 78g/mole
Therefore, molecular formula for benzene is C6H6
