<span>This type of reaction is called a synthesis reaction. This type of reaction occurs when two or more components combine to form a single compound. During this formation, heat and energy is released, ergo it is an exothermic type of reaction.</span>
It is either a proton or a neutron . B

How to identify the particle</h3>
The particle labeled with an X is a neutral atom or a proton which is symbolically represented as :
AZX
where,
Z = atomic number of the element and is known as the number of protons and number of electron (in the particle)
A = Mass number of the element which is represented as the sum of the protons and neutrons (in the nucleus)
Thus, the statement that best identifies the particle X is that it is either a proton or a neutron

Answer:
11 protons and 11 electrons.
Explanation:
Na is a neutral element and element number 11.
This means that it has 11 protons and 11 electrons.
In order to create an isotope, you would add or get rid of neutrons to get different mass numbers but the same element. The number of protons and electrons would remain the same.
Answer:
There is a production of 11.6 moles of CO₂
Explanation:
The reaction is this:
2C₂H₆(g) + 7O₂(g) ⟶ 4CO₂(g) + 6H₂O(g)
2 moles of ethane reacts with 7 moles of oxygen, to make 4 mol of dioxide and 6 moles of water vapor.
If the oxygen is in excess, we make the calculate with the ethane (limiting reactant)
2 moles of ethane produce 4 moles of dioxide
5.8 moles of ethane produce (5.8 .4)/2 = 11.6 moles
When a car undergo a collision, a series of reaction is set off in the airbag section of the car, which makes the air bag to blow out and take the forward movement of the occupants of the front seat. One of the chemicals produced during this reaction is sodium. Sodium has high capacity to react with water in order to become sodium hydroxide, which is a concentrated base and can be quite harmful to the occupants of the car. In order to avoid this, car manufacturer mix sodium azide (the major chemical in the air bag) with other chemicals, which will react with sodium to produce less toxic compounds.
