Ответ:

1)SiH4(lV,l),Ca5P2(ll,V),SO3(Vl,ll),As2O5(V,ll),CrO3(Vl,ll),Mn2O7(Vll,ll),Mn5N7(Vll,V)

2)N2O3(lll,ll),AlCl3(lll,l),Cl2O7(Vll,ll)(Ты скорее всего неверно ввёл(ела)),AlF3(lll,l),Al2S3(lll,ll),PH3(lll,l),CO2(lV,ll)

Объяснение:

в 1 задании там по порядку обозначены валентности сполук, в SiH4:Si lV, в H l и так далее

Answer 2

Formulas and Valence of Compounds:

The formulas for the compounds you mentioned are as follows: - SiH - CaP - SO - AsO - CrO - MnO - MnN

To determine the valence of the atoms in these compounds, we need to consider the charges of the ions involved. The valence of an atom represents the number of electrons it gains, loses, or shares when forming a chemical bond.

Unfortunately, I couldn't find specific information about the valence of the atoms in the compounds you mentioned. However, I can provide some general information about the valence of the elements involved.

Valence of Elements in Compounds:

1. SiH: Silicon (Si) typically has a valence of +4, while hydrogen (H) has a valence of +1. 2. CaP: Calcium (Ca) usually has a valence of +2, and phosphorus (P) can have a valence of -3, +3, or +5, depending on the compound. 3. SO: Sulfur (S) typically has a valence of -2, and oxygen (O) has a valence of -2. 4. AsO: Arsenic (As) can have a valence of -3 or +3, and oxygen (O) has a valence of -2. 5. CrO: Chromium (Cr) can have different valences, such as +2, +3, or +6, depending on the compound. Oxygen (O) has a valence of -2. 6. MnO: Manganese (Mn) can have different valences, such as +2, +3, +4, +6, or +7, depending on the compound. Oxygen (O) has a valence of -2. 7. MnN: Manganese (Mn) can have different valences, such as +2, +3, +4, +6, or +7, depending on the compound. Nitrogen (N) typically has a valence of -3.

Valence of Atoms in Other Compounds:

1. N2O3: Nitrogen (N) typically has a valence of -3, and oxygen (O) has a valence of -2. 2. AlCl3: Aluminum (Al) usually has a valence of +3, and chlorine (Cl) has a valence of -1. 3. Cl2: Chlorine (Cl) typically has a valence of -1. 4. O7: Oxygen (O) typically has a valence of -2. 5. AlF3: Aluminum (Al) usually has a valence of +3, and fluorine (F) has a valence of -1. 6. Al2S3: Aluminum (Al) usually has a valence of +3, and sulfur (S) can have a valence of -2 or +6, depending on the compound. 7. PH3: Phosphorus (P) typically has a valence of -3, and hydrogen (H) has a valence of +1. 8. CO2: Carbon (C) typically has a valence of +4, and oxygen (O) has a valence of -2.

Please note that the valence of an element can vary depending on the compound it forms. The information provided here is based on general trends and may not apply to all compounds.
