Answer:
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
Explanation:
Chemical formula = C₇H₈N₄O₂
Elements present:
carbon
hydrogen
nitrogen
oxygen
Number of atoms of each element.
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
The statement which correctly describe the relationship between the reactants and the yield is this: 'the theoretical yield is calculated from the amount of the limiting reactants present'. The theoretical yields is the ideal maximum amount of a product that can be produced during a chemical reaction while the limiting reactant is the reactant that determines the maximum amount of product that can be formed.
The answer should be neutrons electrons and protons
Answer:
The cost of electricity for 100 W power bulb = $ 32.85
Cost of electricity for 0.025 W fluorescent bulb = $ 8.2125
Explanation:
Cost of electricity = $ 0.18 per KW-H
Time = 5 hour per day
Bulb power = 100 W = 0.1 KW
Fluorescent bulb power = 25 W = 0.025 KW
(a) Cost of electricity for 100 W power bulb
0.1 × 5 × 365 × 0.18 = $ 32.85
(b) Cost of electricity for 0.025 W fluorescent bulb
0.025 × 5 × 365 × 0.18 = $ 8.2125
Therefore the cost of electricity for 100 W power bulb = $ 32.85
Cost of electricity for 0.025 W fluorescent bulb = $ 8.2125
Answer:
