The appropriate number of bonds around each carbon atom are four covalent bonds
Please note that carbon has four valence electrons in its outermost shell
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.
An atom is the smallest unit or part of an element which can take part in a chemical reaction.
On a general note, elements are classified as thus:
- Metals, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,
So therefore, the appropriate number of bonds around each carbon atom are four covalent bonds

The answer to the given question above would be the first option. The one that is an example of <span> the conversion of electrical energy to electromagnetic energy is a NUCLEAR FUSION. Somewhat, electrical energy and electromagnetic energy are similar in a way that their energies both travel in waves. Hope this answers your question.</span>
A spontaneous flow of thermal energy takes place from hot to cold. In order to flow thermal energy from a colder object to a hotter object, the work has to be implied on the system. The particle at higher temperature exhibits more kinetic energy in comparison to the particle at a lower temperature. Thus, there is a continuous flow of heat between the objects from the higher temperature to the lower temperature.
Answer:
Chemical reaction B governs the process
Explanation:
The first part of the question asks to convert the mass of the calcium carbonate given to number of moles.
Mathematically;
Number of moles = mass/molar mass
Molar mass of CaCO3 = 100 g/mol
So the number of moles of CaCO3 will be 2.49/100 = 0.0249 moles
The second part of the question asks to convert the mass of carbon iv oxide to moles of carbon iv oxide
Mathematically;
That is same as ;
Number of moles = mass/molar mass
molar mass of CO2 is 44 g/mol
Number of moles of CO2 = 1.13/44 = 0.0256 moles
Now, if we compare the values of these number of moles, we can see that there are almost equal.
What this means is that the number of moles of calcium carbonate reacted is equal to the number of moles of carbon iv oxide produced.
So what we conclude here is that we have an equal mole ratio between the two compounds.
So the reaction that would be the correct answer will present equal number of moles of carbon iv oxide and calcium carbonate
Thus, we can see that reaction B is the one that governs this process as it is the only reaction out of the three options that present the two compounds with equal number of moles.
