Question

Рассчитайте валентность H PO3, CuO(II) AI OH, CO(II), NO(V)

Answer 1

HPO3 - H валентность 1, PO3 валентность 1
CuO - валентность меди 2, кислорода 2
AlOH - может Al (OH)3, т. к. у алюминия валентность постоянная 3, а у OH от индекса водорода 1
CO - так и оставляем валентность кислорода 2, а углерода тоже 2
NO - N2O5, т.к. валентность кислорода постоянна то есть 2, а валентность азота 5

Как то так, если имели ввиду что то другое то...

Answer 2

HPO3, CuO AI(OH)3, CO), N2O5

Answer 3

Valency of HPO3

The valency of a compound is a measure of its combining power with other elements. To calculate the valency of HPO3, we need to determine the charges of the elements involved.

In HPO3, the element H is hydrogen and the element PO3 is a polyatomic ion called phosphate. The phosphate ion (PO3) has a charge of -3. Hydrogen typically has a charge of +1 when it forms compounds.

To calculate the valency of HPO3, we can use the following formula:

Valency of HPO3 = (Valency of H) + (Valency of PO3)

Since hydrogen has a valency of +1 and the phosphate ion (PO3) has a charge of -3, the valency of HPO3 can be calculated as follows:

Valency of HPO3 = (+1) + (-3) = -2

Therefore, the valency of HPO3 is -2.

Valency of CuO(II)

CuO is a compound composed of the elements copper (Cu) and oxygen (O). To determine the valency of CuO, we need to determine the charges of the elements involved.

In CuO, copper (Cu) typically has a charge of +2 when it forms compounds, while oxygen (O) typically has a charge of -2.

To calculate the valency of CuO, we can use the following formula:

Valency of CuO = (Valency of Cu) + (Valency of O)

Since copper has a valency of +2 and oxygen has a valency of -2, the valency of CuO can be calculated as follows:

Valency of CuO = (+2) + (-2) = 0

Therefore, the valency of CuO is 0.

Valency of Al(OH)

It seems there might be a typo in the query. The compound Al(OH) is incomplete, as it should have a subscript to indicate the number of hydroxide (OH) groups attached to the aluminum (Al) ion. Please provide the correct formula, and I will be happy to help you calculate the valency.

Valency of CO(II)

CO(II) is not a recognized compound. It seems there might be a typo or misunderstanding in the query. If you meant to ask about the valency of carbon monoxide (CO), it is important to note that carbon monoxide is a neutral molecule and does not have a valency in the same way that ions or polyatomic ions do. The valency concept is typically used to describe the combining power of elements in ionic compounds.

Valency of NO(V)

NO(V) is not a recognized compound. It seems there might be a typo or misunderstanding in the query. If you meant to ask about the valency of nitrogen pentoxide (NO5), it is important to note that nitrogen pentoxide is not a stable compound. The most common form of nitrogen pentoxide is N2O5, which is a covalent compound. In covalent compounds, the concept of valency is not typically used to describe the combining power of elements.
