A. hydroxide is the answer
Answer:
0.004012km
Explanation:
Problem:
Conversion of millimeters(mm) to Kilometers:
value given = 4012mm
Here, we are converting from a submultiple unit to a multiple unit.
Millimeter depicts 10⁻³m and kilometer stands for 10³m
Now, we must find how many exponents will take us from 10⁻³ to 10³
careful examination shows that if we multiply a power of 10⁶ to 10⁻³ it will give a 10³:
i.e 10⁻³ x 10⁶ = 10⁻³⁺⁶ = 10³
Therefore,
10⁶mm = 1km
4,012mm = = 0.004012km
Answer:
New temp = 135°C
Explanation:
From ideal gas equation
But; P1 = 10000Pa. P2 = 45000
V1 = 200 cc. V2 = 100 cc
T1 = 60°C. T2 = ??
From our formulae above
then T2= 45000×100×60÷ (10000×200)
T2= 135°C
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,
