So, i know that if a metal mixes with an acid it produces salt + hydrogen
and i was just wondering... what happens if a METAL OXIDE is mixed with an acid ?
thanksss, <3

The evidence that can demonstrate the covalent nature of water is
Further Explanation:
The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals.
Following are some of the properties of covalent compounds:
1. These are brittle solids.
2. Low melting and boiling points.
3. Poor conductors of heat and electricity.
4. Low enthalpy of fusion.
Boron trichloride , silicon dioxide , and xenon hexafluoride are some examples of covalent compounds.
(A). Water is a liquid that has a definite volume. The physical property can be determined without knowing the chemical nature of the substance. Therefore the liquid state of water with a fixed volume is not able to predict its chemical properties and determination of the type of compound comes under these properties. So it cannot predict the covalent nature of water. Hence, the option (A) is incorrect.
(B). Boiling of water on a kitchen stove does not allow its temperature to reach a certain higher limit. This indicates that it boils at a moderate temperature due to which it is clear that water has low boiling point. As we know, boiling points of covalent compounds are low due to the presence of weak intermolecular forces between them. This proves water is a covalent compound. Hence, the option (B) is correct
(C). Water is a covalent compound. As we know covalent compounds are formed by the mutual sharing of electrons. So their electrical conductivity of covalent compounds is very low due to the absence of free ions in them and therefore this property cannot show the covalent nature of water molecule. Hence, the option (C) is incorrect
(D). Water can change its shape and can be sprayed or poured. This shows water has some fluidity in it and has intermediate forces of attraction. But it gives no idea about whether water is a covalent compound or not. So this property cannot be used to predict the covalent nature of water molecule. Hence, the option (D) is incorrect
