Answer:
The compound with the correct formula is;
A. MNO₃
Explanation:
The number of oxidation states in the metal, M = One oxidation state
The formula of the compound formed by the metal, M = MHCO₃
We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1
Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;
The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.
When a substance is undergoing a change of state, the heat that is been added to the substance at that particular point in time is used to work on the chemical bonds that is holding the molecules of the substance together; the heat is not used to increase the temperature of the substance at that particular point. For instance, in the case of ice, at its melting point the heat supplied is used to break the inter molecular force that is holding the particles of the ice together. When the bonds are completely broken and the ice has to liquid then the temperature of the water will increase.
Answer:
false
Explanation:
earth is larger than mars so it has more gravity
Because oxygen is more electronegative<span> than hydrogen. The oxygen atom in h2o pulls electrons towards itself, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. oppositely charfed ends of</span>water molecules<span> are attracted to each other, forming a hydrogen bond</span>
The charge of an atom is usually neutral
