To calculate it using the formulas and learn about drug.

What is drug?

Drugs are by definition chemicals that, when ingested into a living system, influence or modify physiology. Both natural and artificial materials are acceptable. They are low-mass chemical structures, both in terms of atomic and molecular mass.

What is chemist?

At the atomic and molecular levels, chemists look into the characteristics of matter. They gauge proportions and reaction rates to better comprehend new substances and their behavior or to develop novel compounds for use in a variety of real-world scenarios.

Ratio of the compounds A and B are given as

compound A: compound B= 6:5

Now, chemist own to make a drug of 814ml, so we have to distribute these 814 ml in the ratio of 6:5. To make chemically correct drug.

Amount of compound=6/(6+5*814)

=6/11*814=444 ml

∴ Amount of compound a is needed 44 ml.

Therefore, 44 millimeters of a compound are needed.

How does the density of protostars compare to other stars?
lorasvet [3.4K]

Protostars are less dense than other stars.  

Explanation:

Protostars are very young ‘stars’ made from hydrogen clouds that are beginning to coalesce and collapse under their weight. The hydrogen has not even begun fusing. Therefore, they are mainly made of hydrogen which is the lightest element in the universe.

Stars, however, have begun fusing hydrogen to other heavier elements like helium, carbon, oxygen, and iron. The elements are much heavier than hydrogen making other stars much denser than protostars.

How does the arrangement of elements in periods relate to electron configuration
VashaNatasha [74]
Electronic Configuration of elements in a period is same because If you see the electronic Configuration of elements in a period you will notice that the valence shell electrons for all elements are present in the same Shell. For example, in first period consisting of Hydrogen and Helium, both the elements' valence electrons are present in the same Shell.
Electronic Configuration of Hydrogen,
1s^1
Electronic Configuration of Helium,
1s^2

Both elements' valance electrons are present in the 1st shell

(This is just a small example to understand the concept because other periods are long but the first period is short that's why I gave the example of the first period)

An object has a mass of 5 kg. What force is needed to accelerate it at 6 m/s2? (Formula: F=ma) 0.83 N 1.2 N 11 N 30 N
masya89 [10]
Answer: Option (D) 30N

Detailed Solution:
According to Newton's second law:

F = ma --- (A)

Given:
mass = 5kg
acceleration = 6 m/s^2
F = ?

Plug all the value in equation (A)
F = (5)(6)
Ans: F = 30N
