1. False

Elements bond to form compounds.

Consider that compounds are essentially clumped up atoms. Knowing this, we know that atoms don’t separate, but rather combine in order to make compounds.

2. True

3. False

Atoms cam lose or gain electrons to form ionic bonds.

When at atom doesn’t have enough electrons to become stable, it will either give or take electrons from another atom in order to become stable. However, because of the fact that the atoms become oppositely charge, they attract each other, thus forming an ionic bond

Ca(s)+2hno3(aq)→ca(no3)2(aq)+h2(g) identify the oxidizing agent.
aleksandr82 [10.1K]

To find for the oxidizing agent, first let us write the half reactions of this complete chemical reaction:

Ca = Ca2+ + 2e- <span>
2 H+ + 2e- = H2</span>

 

The oxidizing agent would be the substance of the element that is reduced. We know that an element is reduced when an electron is added to it. In this case, the element being reduced is H. Therefore the oxidizing agent is HNO3.

 

Answer:

<span>HNO3</span>
