We can exemplify with H2O (water)
H= nonmetalic
O= Nonmetalic
A bond with nonmetalic and nonmetalic is covalent bond.
Hope it helps!!

<span>The chemical equation for the Vinegar & Baking Soda reaction is:
NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)
with s = solid, l = liquid, g = gas, aq = aqueous or in water solution
Another reaction is:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The chemical reaction actually occurs in two steps.
First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Then,Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3 → H2O + CO2</span>
Explanation:
your anawer to the question is A. V and Rb
Answer:
Shiny, conduct heat and electricity well, malleable.
Explanation:
Answer:
oxidation occurs at the cathode.
Explanation:
In a voltaic cell electrons move from anode to cathode. At the anode, species give up electrons. This is an oxidation reaction depicted by the oxidation half equation. At the cathode, species accept electrons and become reduced. This is depicted by the reduction half equation. In summary; in a Voltaic cell, oxidation occurs at the anode while reduction occurs at the cathode.
