Question

1.Складіть формулми бінарних сполук за відомою валентністю елементів з Оксигеном. Li,S(lll),Ca.Дайте назви сполукам і класифікуйте їх за типами оксидів(основні чи кислотні)​

Answer 1

Відповідь:

Ок

Пояснення:

Li2O-літій оксид, осовний оксид

S-незнаю бо у сульфуру не може бути валентність ІІІ може бути ІІ IV VI

SO2-сульфур(IV) оксид, кислотний оксид

SO3-сульфур(VI) оксид, кислотний оксид

CaO-кальцій оксид, основний оксид

Answer 2

Binary Compounds with Oxygen

To determine the formulas of binary compounds with oxygen, we need to consider the valency (or oxidation state) of the elements involved. Here are the examples you provided:

1. Lithium (Li): - Valency of lithium is +1. - The formula for the binary compound of lithium with oxygen is Li2O. - This compound is classified as a basic oxide.

2. Sulfur (S): - Valency of sulfur can vary. In this case, it is given as +4. - The formula for the binary compound of sulfur with oxygen is SO2. - This compound is classified as an acidic oxide.

3. Calcium (Ca): - Valency of calcium is +2. - The formula for the binary compound of calcium with oxygen is CaO. - This compound is classified as a basic oxide.

So, the compounds formed with oxygen and the given elements are:

- Lithium oxide (Li2O) - a basic oxide. - Sulfur dioxide (SO2) - an acidic oxide. - Calcium oxide (CaO) - a basic oxide.

Please note that the valencies provided are specific to the examples given. The valency of an element can vary depending on the specific compound it forms.
