What determines the number of hydrogens in an acid?

Answers

Answer:

It's the same as the charge of the anion

Explanation:

What determines the number of hydrogens in an acid is the charge of the corresponding anion. This is otherwise termed the Basicity of the acid

According to the question;

We are required to identify what determines the number of hydrogens in an acid.

An acid is typically made up of an Hydrogen ion(Cation) and another anion.

For instance:

HCl is made up of 1 H+ ion and 1 Cl- ion.

While, H2SO4 is made up of 2 H+ and one SO4²- ion.

Which change of state is shown in the model?

condensation
deposition
boiling
freezing

Answers

Answer:

deposition

Explanation:

The model above shows a transition from a gas state to a solid state. This is known as "deposition."

The particles are widely-spaced on the left because they have a lot of energy; thus, they don't interact with each other. This is the reason why the gas doesn't have a definite shape and volume.

The particles on the right are stacked near the bottom because they don't have enough energy to move about; thus they interact with each other. This gives solid a definite shape and a definite volume. They can only move if the thermal energy increases.

Which of the sets of elements are not in order of increasing force of attraction on the outermost electron in atoms of that element?

Ba < Sr < Ca
Al < P < Cl
F < Cl < Br
Mo < Pd < Sn

Answers

Answer:

The set of elements that are not arranged in the order of increasing ionization energy is Mo < Pd < Sn

Explanation:

The force of attraction on the outermost electron of an element can be described by the ionization energy of the element which decreases down a group and increases across a period

1) The given elements Ba, Sr, Ca, are group 2 elements arranged in the order from bottom up, which gives an increasing ionization energy, therefore;

Ba < Sr < Ca is arranged in increasing ionization energy, and therefore, increasing force of attraction of the outermost electron in atoms of the elements

Similarly, Al < P < Cl and Mo < Pd < Sn, are arranged in order of increasing ionization energy

However F < Cl < Br which are arranged from top down of elements in period 17 are arranged in the order of decreasing ionization energy, and therefore, decreasing force of attraction of the outermost electron in atoms of the elements.

The elements that are not arranged in their increasing force of attraction base on the outermost electron present in their atoms is D:

Mo < Pd < Sn.

Ionization energy of an element usually increase when moving along the period and decreases down a group and thus explains the force of attraction on the outermost electron.

Option A are arranged in from down to up of group 2, which means they are in increasing order of ionization energy, same thing with option B, C. But option D, doesn't follow the arrangements hence, the correct answer.

Therefore , option D is correct.

How many moles of salt do you have, if you have 5.00 x 10^26 formula units of salt?

Answers

Answer:

830.56 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L}\\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{5.00 \times {10}^{26} }{6.02 \times {10}^{23} } \\ = 830.5647..[/tex]

We have the final answer as

830.56 moles

Answer:

True.

But it only changes in physical change.

How?

Explanation:

The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance.

In a physical change, a substance's physical properties may change.

A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. ... Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
