Given the unbalanced equation which represents aluminum metals reacting with an acid:

Chemistry
1 answer:
Alona [7]2 years ago
7 0

There are three number of electrons lost by 1 mole of aluminium because aluminum has +3 charge on it.

<h3>What is cation?</h3>

When an atom loses electron, positive charge appears on the atom this is called cation. In this reaction we can see that aluminium has +3 charge which means that it loses 3 electrons.

So we can conclude that There are three number of electrons lost by 1 mole of aluminium because aluminum has +3 charge on it.

Exhibits the highest intermolecular<br> forces of the states of matter.
disa [49]

Answer:

Solid

Explanation:

In solid there are strong intermolecular forces present as compared to liquid and gas. This is why solid are in more packed form as compared to liquid and gas. In liquid and gas intermolecular forces are week that's why molecules are away from each other and occupy more space.

Properties of gases:

Molecule of gases randomly move everywhere and occupy all available space.

Gases don't have definite volume and shape and take the shape and volume of container in which it present.

Their densities are very low as compared to the liquid and solids.

Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.

The very weak inter molecular forces are present between gas molecules.

Properties of Liquid:

Liquid have definite volume but don't have definite shape.

Their densities are high as compared to the gases but low as compared to the solids.

In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.

Properties of solids:

Solids have definite volume and shape.

In solids molecules are tightly pack and very close to each other.

Their melting and boiling point are every high.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.

Which represents the empirical formula for a3B9
Viktor [21]
A3B9 represents a molecular formula. The representation of the empirical formula for this compound is AB3. This is so because the empirical formula is the simplest ratio of the atoms present in the molecule. You get AB3 when you divide the subscripts of A3B9, this is 3 and 9, by the greatest common factor, which is 3. 3/3 = 1 and 9/3 = 3, so the subscripts for the empirical formula are 1 and 3, which is what AB3 represents. <span>Answer: AB3.</span>

If the order of a reaction with the regard to reagent A is 2, when the concentration of A doubles, the rate will
Anarel [89]

Answer:

Rate will double

Explanation:

Since the concentration of A is doubling the rate of reaction will also double, since in this scenario concentration is proportional to rate of reaction. So if the concentration of A were to triple the rate of reaction would also triple.

Flauer [41]
It is an example of physical change. The molecules are not changing, so it is not chemical, and a physical property is something that a physical thing has.
