A positive ion has moreA. protons than electrons
B. electrons than protons
C. neutrons than protons
Answers
Final answer:
A positive ion, also known as a cation, has more protons than electrons as a result of losing electrons. For example, a sodium atom becomes a +1 sodium ion when it loses an electron. The number of neutrons does not affect the charge of ions.
Explanation:
A positive ion, also known as a cation, is formed when an atom loses one or more electrons. This causes the atom to have more protons than electrons, thereby gaining a positive charge. So, the correct answer to your question is A. Protons than electrons.
For instance, when a sodium atom (which has 11 protons and 11 electrons) loses an electron, it becomes a sodium ion with a +1 charge, having 11 protons and only 10 electrons.
Neutrons are particles present in the nucleus of an atom that do not carry any charge. Hence, the number of neutrons doesn’t affect the charge of ions.

Final answer:
A positive ion, or a cation, has more protons than electrons because it forms by losing electrons. Therefore, it has a net positive charge. The number of protons and neutrons doesn't change during this process.
Explanation:
A positive ion, also known as a cation, is formed when an atom loses electrons. The loss of electrons results in the atom having more protons than electrons, and subsequently more positive charge than negative, hence the name positive ion. Therefore, the correct answer to your question is A. protons than electrons. However, it’s important to note that the number of protons and neutrons in an atom does not change during chemical reactions or during the formation of ions.

The equation is not balanced because the number of atoms of Oxygen present in the reactants and product sides are not equal
The equation being referred to in the question can be written properly as
S + 3O₂ → SO₃
To determine whether the equation is balanced or not
We will check if the coefficient in the equation gives equal numbers of atoms for each element in the reactants and product
- For the reactants side
S = 1
O = 6
- For the product side
S = 1
O = 3
We can observe that, the coefficient does not give equal number of atoms for the element, Oxygen (O), in the reactants and product sides
∴ The equation is NOT balanced
Hence, the equation is not balanced because the number of atoms of Oxygen present in the reactants and product sides are not equal

Answer:
This equation is not balanced because you don't have the same amount of each element on each side of the chemical reaction. The balanced equation is:
2 S + 3 ⇒ 2
Explanation:
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by sub-index 2)
Right side: 1 sulfur S and 3 oxygen O (subindice value)
As you can see, you have the same amount of sulfur on both sides of the equation but the amount of oxygen is different. This indicates that the chemical equation is not balanced. To balance it, as the amount of sulfur is the same, the amount of oxygen must be balanced, which is different on each side of the reaction.
A simple way is to balance the equation is to multiply the product by 2, that is, add a coefficient 2 in front of the SO3 molecule, the reaction being as follows:
S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
The oxygen is now balanced, but the amount of sulfur on both sides of the reaction varies. To balance the quantities of sulfur, as now on the right side you have an amount of 2, you can add the coefficient to sulfur. The chemical equation is as follows:
2 S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 2 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
Finally you have the same amount of sulfur and oxygen on both sides of the reaction. So the chemical equation is finally balanced.

Answer:
A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil
Explanation: Factors That Affect the Boiling Point
Pressure: when the external pressure is:
less than one atmosphere, the boiling point of the liquid is lower than its normal boiling point.
equal to one atmosphere, the boiling point of a liquid is called the normal boiling point.
greater than one atmosphere, the boiling point of the liquid is greater than its normal boiling point.
The following graph shows the boiling point for water as a function of the external pressure. The line on the graph shows the normal boiling point for water.
