D. Experiments provided new evidence about the atom, I think, sorry if I’m wrong
i may be wrong but i think its B. neutralization
Answer:
I think its A. It accepted radiation in a chemical reaction, hope this helped.
Answer:
165.52 g/mol
Explanation:
Upon temperature was raised to 100 C part of the initial mass of liquid is gas, exactly: 2.00-0.581 = 1.419 g. This gas occupy a volume of approximately 265 mL, its pressure of 752 mm Hg and its temperature is 100 C. Assuming that this gas behaves as gas ideal we can estimate the molecular weight taking into account tha gas ideal law:
with R= 0.082 atm L/(mol K)
or
Before using of the formula, we need convert volume units to L (1L=1000 mL) pressure to atm (1 atm=760 mmHg) and temperature to K (K=273+C).
Finally, replacing in the formula
g/mol
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,
