Neon is used in lighting advertising displays.
Which statement can be applied to an atom of neon?
A The atom has the same electron arrangement as Cl– ion.
B The atom has two more electrons than an atom of oxygen.
C The atom has the same number of outer electrons as an atom of helium.
D The atom has the same number of electrons as a Ca2+ ion.
Answer:
B. The atom has two more electrons than an atom of oxygen.
Explanation:
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.
This ultimately implies that, an [tex] O^{2-} [/tex] atom contains the same number of electrons as an atom of neon.
Hence, a neon atom has two more electrons than an atom of oxygen.
Additionally, Neon is used in lighting advertising displays.

yes,
Na + O2 → Na2O2
Can you guys help me !
Answer:
Explanation:
Assuming that you are asking for the full-balanced equations...
2Na + O2 = Na2O2
H2 + O2 = H2O2; This equation is already balanced, there is no need for change.
Please let me know if this is not the answer you are looking for and I will amend the answer.
A 5.00 gram sample of water is heated so that its temperature increases from 10.0°C to 15.0°C. What is the
total amount of energy absorbed by the water?
Answer:
15.0°C
Explanation:
hope it helps
Heat Capacity
The heat capacity of a substance can be defined as the amount of heat required to change the temperature by a given amount the SI unit is joules per kelvin
The energy absorbed by the water is 105 joules
Given data:
mass of water = 5 grams
Change in temperature = 10 degrees from 15 degrees
The expression for the Quantity of heat is given by
Q = m x c x Δθ
Where m =mass
c = specific heat capacity and
Δθ = change in temperature
c = 4.2J/g/degrees
Q = 5 x 4.2 x (15 - 10)
Q = 5 x 4.2 x 5
Q = 105Joules

What is the relationship between temperature and kinetic energy?
When all molecular motion stops, the temperature stop charging.
As molecules move more quickly, temperature increases.
When all molecular motion stops, the temperature starts to decrease.
As a molecules slow down, temperature starts to increase.
Answer:
As molecules move more quickly, temperature increases.
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Any material or object that allow the conduction (transfer) of electric charge or thermal energy is generally referred to as a conductor. Some examples of a conductor are metals, copper, aluminum, graphite, etc.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
Hence, the relationship between temperature and kinetic energy is that as molecules move more quickly, temperature increases due to the absorption of heat.

1. According to the equation, what mass of hydrogen fluoride is necessary to produce 2.3 g of sodium fluoride?
HF + NaNO3 -> HNO3 + NaF
Answer:
1.09 grams
Explanation:
According to the following chemical equation:
HF + NaNO₃ -> HNO₃ + NaF
1 mol of hydrogen fluoride (HF) produces 1 mol of sodium fluoride (NaF). Thus, we first convert from mol to grams by using the molar mass (MM) of each compound:
MM(HF)= (1 g/mol x 1 H) + (19 g/mol x 1 F) = 20 g/mol HF
1 mol HF x 19.9 g/mol HF = 20 g
MM(NaF) = (23 g/mol x 1 Na) + (19 g/mol x 1 F) = 42 g/mol NaF
1 mol NaF x 42 g/mol NaF = 42 g
Thus, from 20 g of HF are produced 42 g of NaF ⇒ 20 g HF/42 g NaF. We multiply this stoichiometric ratio by the mass of NaF produced to calculate the required mass of HF:
20 g HF/42 g NaF x 2.3 g NaF = 1.09 g HF
Therefore, 1.09 grams of HF are necessary to produce 2.3 g of NaF.
b) Write a few paragraphs describing the chemical reaction and explaining the energy change in the reaction. Your document should: i. identify the reactants and products. ii. describe the change in energy that occurs as bonds are broken and formed. iii. identify how the potential energy of the reactants compares to the potential energy of the products. iv. state and explain the net change in enthalpy. v. identify whether the reaction is endothermic or exothermic. vi. explain how energy is conserved between the reaction and the surrounding environment.
Answer:
The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.
Explanation:
if u want to u can give me the crown btw have a good day
Answer:
here is what i put for this project:
The reaction in this project is exothermic. The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy. The potential energy in reactants is higher than the potential energy of products in an exothermic reaction. Since energy is given off, the products are lower in energy than the reactants. The energy that is given off is a result of the formation of new bonds.
The change of the enthalpy happening in the chemical reaction is different from the pathway in between the initial and the final states. The addition of the equation gives the net change of the enthalpy. Enthalpy change is the amount of heat evolved or absorbed in the reaction under constant pressure. This can be calculated by checking the amount of heat evolved during the reaction. This reaction occurs at a constant pressure.

Which of the following is an example of an adaptation that might be useful in the grassland? HELP ME PLS
A. an insect looking like a tree branch
B. an animal having a heavy coat of fur
C. an animal having large feet so it can walk on the snow
D. an animal being the color of brown grass and dust
Answer:
D
Explanation:
In the grassland pretty warm so the heavy fur coat wouldn't help, there is no snow in the grassland so the big feet for walking on snow also wouldn't help, its the grassland where trees are more scarce so not A, but there is a lot of grass and dust so being able to blend in would help.
Answer:
D
Explanation:
AN animal this color can camouflage and it can help them so they will not be eaten by there predators
if I have a +2 oxidation number do I give up or accept electrons?
Answer:
Give up 2 electrons.
Explanation:
Is this ever a good question!!!
Electrons have a minus charge
Protons have a plus charge.
You need to understand it thoroughly. I used to explain it this way.
Suppose the protons and electrons are playing a game and the electrons commit a foul that leaves them with 2 men short.
That means there are 2 unguarded plus's around. The result is that the minuses have lost two men who are in the sin bin. (I watch a lot of hockey).
So a +2 means that the electrons have lost two of their players to penalties.
Put in the vocabulary of your question, you give up 2 electrons.

Lithium 1s22s1
Chlorine 1s22s22p6 3s23p5
A. 1:1
B. 1:2
C. 2:1
D. 3:1
D. 3:1
Answer:
A. 1:1
Explanation:
Lithium 1s2 2s1
Chlorine 1s2 2s2 2p6 3s2 3p5
Lithium is a group 1 element. When it forms a compound, it loses it's one valence (outermost) electron.
Chlorine is a group 7 element. When it forms a compound, it gains one electron to achieve a stable electronic configuration.
Since Li loses one electron and Cl gains one electron. The formular of the compound formed would be;
LiCl
The correct option is;
A. 1:1
