Answer:
the answer of the question is c
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
Answer:the 5g would be more dense due to the mass and structure
Of it causing the atoms to expand as heat gets added
Explanation:
I think the statement is false. Natural elements do reflect light. Almost everything in this world reflect light. Reflection<span> is when </span>light<span> bounces off an object. Hope this answers the question. Have a nice day.</span>
Answer:
The five steps involved in the process of natural selection are
Variation • Inheritance • Selection • Time • Adaptation
