Explanation:
A cation is a positively charged ion.
An anion is a negatively charged ion.
- In a cation, electrons are usually lost
- In an anion, electrons are usually gained.
In an atom, the balance between the number of protons and electrons determine whether they become an anion or cation.
Protons are positively charged particles.
Electrons are negatively charged
When an atom gains electrons, the number of electrons becomes more than that of protons. This leaves a net negative charge on the atom and it makes an anion.
When an atom loses electrons, the number of protons becomes more than that of electrons. This leaves a net positive charge on the atom and makes a cation.
The answer is a. the smallest unit of matter that maintains its chemical identity.
The largest amount of CO₂ produced when 2 moles of C₂H₂ reacted with 1 mole of O₂ is 0.8 mole
We'll begin by writing the balanced equation for the reaction. This is given below:
2C₂H₂ + 5O₂ —> 4CO₂ + 2H₂O
2 : 5
2 : 1
From the balanced equation above,
We can see that O₂ is the limiting reactant as lesser amount of it is available.
Finally, we shall determine the largest amount of CO₂ produced by using the limiting reactant as illustrated below:
From the balanced equation above,
5 moles of O₂ reacted to produce 4 moles of CO₂.
Therefore,
1 mole of O₂ will react to produce = 4/5 = 0.8 mole of CO₂.
Thus, the largest amount of CO₂ produced from the reaction is 0.8 mole
