Answer & Explanation:

As an Alka-Seltzer tablet dissolves in water, it liberates carbon dioxide. ... This carbon dioxide gas has mass, but since it is a gas it escapes from the container and diffuses into the atmosphere. The loss of mass from the container is measured directly with the analytical balance.

Answer:

It produces carbon dioxide when an Alka-Seltzer tablet dissolves in water. In the bath, the carbon dioxide dissolves and then emerges as a gas from the solution.

This carbon dioxide gas has mass, but it escapes from the container and diffuses into the atmosphere because it is a gas.

The mass loss from the container is directly calculated by the analytical balance.

Zinc phosphide, Zn3P2, is often used as a rat poison. Phosphorus has 5 valence electrons. Assuming that phosphorus is following

Nadya [2.5K]

Answer:

Two electrons each!

Explanation:

The question pretty much requires us to find the oxidation number of Zinc in the compound.

Zn3P2

Following oxidation number rules;

O.N of Zn3P2 = 0

.Since phosphorus has valence of 5, it needs three more electrons to achieve its octet state. Hence;

Oxidation number of P = -3

Let oxidation number of Zn = x

We have;

3x + 2 (-3) = 0

3x + (-6) = 0

3x = 6

x = 6/3 = 2

This means each zn electrons lost 2 electrons.

An acid has a molarity of 0.01 M. What does the 0.01 M refer to?

Delvig [45]

So molarity which is represented by that 0.01M refers to the amount of moles that is present in 1L or 1dm³ of the substance, in this case the acid. Molarity refers to CONCENTRATION therefore and has little to do with the strength of the acid (the strength is dependent on the pH).

Thus your answer is OPTION B

mr Goodwill [35]

Answer:

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Hydrogen bonding occurs in molecules when a _____________. (1 point)

Burka [1]

Answer: hydrogen atom of a polarized molecule bonds with an electro negative atom.

Explanation:

Hydrogen bonds are special type of dipole dipole forces which are formed when hydrogen bonds with an electro negative element. Hydrogen bonds are strongest type of bonds .Example: Bond between Oxygen of one water molecule to the hydrogen of another water molecule as shown in the image below.

Covalent bonds are formed by sharing of electrons among non metals.

Ionic bond is formed by transfer of electrons between metals and non metals.
