A chemistry student needs 30.0 g of acetic acid for an experiment. He has available 1.2 kg of a 7.58% w/w solution of acetic aci

Tomtit [17]

Answer:

The mass of solution will be "395.78 g".

Explanation:

Given:

Mass of acetic acid,

= 30 g

Percentage,

= 7.58% w/w

Now,

⇒ % $=\frac{Mass \ of \ acetic \ acid}{Mass \ of \ solution}\times 100$

By putting the values, we get

⇒ $7.58=\frac{30}{Mass \ of \ solution}\times 100$

⇒ $Mass \ of \ solution=\frac{30\times 100}{7.58}$

⇒ $=\frac{3000}{7.58}$

⇒ $=395.78 \ g$

What Is a high-temperature physical state of matter in which atoms lose their electrons?

AlladinOne [14]

Answer:

A plasma.

Step-by-step explanation:

A plasma is a hot, ionized gas in which the atoms have lost one or more of their electrons.

Thus, the plasma consists gaseous ions as well as the electrons that were stripped from them.

The Sun's high temperatures strip the electrons from its hydrogen and helium atoms, so the Sun is essentially a giant ball of plasma.

Compound B, C6H12O2, was found to be optically active, and it was oxidized to an optically active carboxylic acid A, by Ag (aka,

Daniel [21]

Answer:

Check the explanation

Explanation:

Acidipic Acid (which is an essential dicarboxylic acid for manufacturing purposes with about 2. 5 billion kilograms produced per year. It is mainly used for the production of nylon and its related materials.)

Going by the question, since the $H_{2} CrO_{4}$ is comparatively mild oxidizing agent than the $CrO_{3}$ , it only oxidizes the carbon group
