Answer:
Copper
Explanation:
copper is used in the wiring of the phone
Lithium atoms contain 3 protons, 3 electrons, and 4 neutrons, so the statement is Correct
Answer:
The answer to your question is: C₂H₆O₁ = C₂H₆O
Explanation:
Data
CxHyOz
mass = 40 g produced 76.40 g of CO2
46.96 g of H2O
Empirical formula = ?
Process
CxHyOz + O2 ⇒ CO2 + H2O
44g of CO2 -------------------- 12 g of Carbon
76.40 g of CO2 --------------- x
x = 20.84 g of Carbon
12 g of Carbon --------------- 1 mol
20.84 g of C --------------- x
x = (20.84 x 1) / 12
x = 1.74 mol of Carbon
18 g of H2O -------------------- 2 g of H
46.96 g of H2O -------------- x
x = (46.96 x 2) / 18
x = 5.22 g of H
1 g of H ------------------------ 1 mol of H
5.22 g of H ------------------- x
x = 5.22 mol of H
Mass of Oxygen = 40 - 20.84 - 5.22g
= 13.94 g
16 g of Oxygen ---------------- 1 mol
13.94 g of O -------------------- x
x = 0.87 mol of O
Divide by the lowest number of moles
Carbon = 1.74 / 0.87 = 2
Hydrogen = 5.22 / 0.87 = 6
Oxygen = 0.87 / 0.87 = 1
Empirical formula
C₂H₆O₁ = C₂H₆O
Hydroxychloroquine cannot be made from grapefruit and lemon rinds.
Hydroxychloroquine is not a natural compound, rather it can only be synthesized from quinoline molecule in the laboratories.
During the synthesis of hydroxychloroquine, several sequential chemical reactions and purifications are done.
Hydroxychloroquine is used in the treatment of:
- malaria
- systemic lupus erythematosus,
- rheumatoid arthritis
But when grapefruit and lemon rinds are boiled in water, a natural chemical compound known as limonene is obtained.
Therefore, hydroxychloroquine cannot be made from grapefruit and lemon rinds,
