Answer:
Carbon Trioxide
Explanation:
Its a Carbonite Ion which is also known as a polyatomic ion
<span>The concentration of the reactant decreases as it is consumed.</span>
Answer:
The answer to your question is:
Re (III) has 5 electrons
Sc(III) = has 1 electron
Ru(IV) = has 6 electrons
Hg(II) = has 10 electrons
Explanation:
75 Re(III) = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d⁵
21 Sc(III) = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹
44 Ru(IV) = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d⁶
80 Hg(II) = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰

Explanation:</h3>
- Chemical reactions occur when compounds or elements combine to form new compounds or other elements.
- Chemical reactions may be classified into various types which include synthesis reactions, replacement reaction, decomposition reactions, and precipitation reactions among others.
- In our case, we were supposed to identify a synthesis reaction.
- Thus, we need to know what is a synthesis reaction.
- A synthesis reaction is a reaction that occurs when two elements or small compounds combine to generate a large compound.
- In this case, B is the choice that shows a synthesis reaction where hydrogen gas combines with oxygen gas to yield water.
