valancy of x is 3 while that of y is 1. write a formula of the compounds when each of the seperaty combines with oxygen

Chemistry

Vaselesa [24]3 years ago

Answer:

X₂O₃ , Y₂O

Explanation:

Valency of an element tells how well that element can form compounds with other atoms.

It sometimes, is also determined by the number of hydrogen atoms that it combines with.

Oxygen usually has a valency of 2, or oxidation state of -2.

That means oxygen will need 2 more electrons in it's outer shell to form a configuration of a noble gas(octet configuration).

The oxidation state of an atom in a molecule gives the number of valence electrons it has gained or lost.

Assuming both X and Y are less electronegative than oxygen, X  has a valency of 3 and OS of +3.

While forming a neutral compound, we need no net charge on the compound. In X₂O₃,

total charge on X is 2 x (OS of X)= 2 x ( +3) = +6

total charge on O is 3 x (OS of O)= 3 x ( -2) = -6

Net charge is 0.

Similarly, in Y₂O

total charge on Y is 2 x (OS of Y)= 2 x ( +1) = +2

total charge on O is 1 x (OS of O)= 1 x ( -2) = -2

Net charge is 0.

How many moles are there in 8.94*10^24 atoms P?
IgorC [24]

Answer:

<h2>14.85 moles </h2>

Explanation:

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

n =  \frac{N}{L} \\

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

n =  \frac{8.94 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\   = 14.850498

We have the final answer as

<h3>14.85 moles</h3>

Hope this helps you

What is the [OH-] if the [H3O+] is 1 x 10 -6?
Mariulka [41]

The answer is [OH⁻] = 1 x 10⁻⁸.

To find OH⁻, divide the ionic product of water by [H₃O⁺] as :

<u>OH⁻ + H₃O⁺ = H₂O</u>

<u />

  • [OH⁻] = 1 x 10⁻¹⁴ / 1 x 10⁻⁶
  • [OH⁻] = 1 x 10⁻⁸
