1) Look at the graph. What is the independent variable and the dependent variable?
Answers
Answer:
Independent Variable = Years
Dependent Variable = Number of Mobiles phone owners
Explanation:
Independent variables are plotted on x-axis and the dependent variables are plotted on y-axis.
In given graph the "Years" belong to x-axis hence, years are the independent variables.
Also, "Number of Mobile phones owners" belong to y-axis hence, this number is the dependent variable.

Answer:
Exothermic reaction
Explanation:
Notice that the energy component is located on the right side of the reaction. The right side is always known as the product side. Whenever energy is located there, the reaction is known to give off energy - essentially, we can say that energy is a product, as well. Reactions that give off energy are known as exothermic reactions.
On the other hand, if the energy component was located on the left side, or reactant side, of the equation, it would be known as an endothermic reaction.
Here, it's exothermic.

Explanation:
-Octet forms when the valence electrons are gained, lost or shared.
-In order to become stable, which has 8 valence electrons (octet), nonmetal groups such as group 17, needs to gain 1 more electron to become 8/ octet.
When gaining that 1 electron, group 17 elements become negative ion or anions
-For metal groups such as group 1, they need to lose that 1 electron to become stable. When they lose that 1 electron, they become positive ion which is cation.

1. All neutral sodium atoms have 11 protons
and 11 electrons.
2. All sodium atoms have the atomic number
11.
3. All sodium atoms have the same number
of protons.
4. All sodium atoms have 11 neutrons.
5. All atoms with atomic number 11 are
sodium atoms.
Answers
All neutral sodium atoms have 11 protons and 11 electrons is about sodium atoms (Na) is not correct. Therefore, option 1 is correct.
Which are neutral atoms?
When an atom has the same number of electrons and protons, it has the same number of negative (electrons) and positive (protons) electric charges (the protons).
As a result, the total electric charge of the atom is zero, and it is said to be neutral. As a result, all elements in the periodic table have neutral atoms.
The sodium atom contains 11 electrons. As sodium atom loses one electron to form sodium ion, sodium ion has ten electrons. Only sodium atoms have a strong reaction with water, whereas sodium ions do not.
Thus, All neutral sodium atoms have 11 protons and 11 electrons is about sodium atoms (Na) is not correct, option 1 is correct.
