Answer:
A. Florine has a stronger pull than Magnesium
Explanation:
Electronegativity refers to the tendency in which an tom would attract electrons to itself.
Below each element in the periodic table is their electronegativity value. Florine has the highest electronegativity value of 4.0.
Going through options;
A. Florine has a stronger pull than Magnesium
Florine = 4.0
Magnesium = 1.2
This correct
B. Hydrogen has a stronger pull than Phosphorus
Hydrogen = 2.1
Phosphorus = 2.1
This is wrong
C. Potassium has a stronger pull than Sodium
Potassium = 0.8
Sodium = 0.9
This is wrong
D. Iron has a stronger pull than Bromine
Iron = 1.8
Bromine = 2.8
This is wrong

When a gas is heated, the gas particles have more kinetic energy. Complete the following sentence: This means they move about more and have more ______ with the sides of the container. This increases the pressure.
Answers
Answer:
Contact
Explanation:
As the speed of the particles increases, they move around more, which means they hit the sides of the container more.

Which Lewis electron-dot diagram correctly represents the reactant containing nitrogen in the equation?
Answers
That leaves us with drawing the structure of NH4Cl.
This was a tough one for me to find, as I kept drawing Ammonia instead and couldnt figure out how to fit in the extra Hydrogen and Chlorine. Luckily, this Y!A answer explains it, its due to a hydrogen bond
Option (1) represents the Lewis electron-dot diagram correctly containing nitrogen in the equation.
Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.
Valence electrons are given by hydrogen atoms = [tex]1\times3=3[/tex]
Valence electrons are given by nitrogen atom = [tex]5\times1=5[/tex]
Total valence electrons = 3 + 5 = 8
So, the calculation above is shown only the first option. So, (1) Lewis electron-dot diagram correctly represents the reactant containing nitrogen in the equation.

determine the kinetic energy of an 833.0 kg roller coaster car moving at a speed of 20.0 m/s
Answers
Answer:
166,600J
Explanation:
Kinetic energy (K.E), which is the energy due to motion of a body, can be calculated by using the formula;
K.E = 1/2 × m × v²
Where;
K.E = kinetic energy (joules)
m = mass of body (kg)
v = speed or velocity (m/s)
According to this question, the mass of the roller coaster is 833.0 kg while its velocity/speed is 20.0m/s.
K.E = 1/2 × 833 × 20²
K.E = 1/2 × 833 × 400
K.E = 1/2 × 333200
K.E = 166,600
Therefore, the kinetic energy of the roller coaster car is 166,600J.

Why can't krypton and xenon separate during the separation of gases in the air?
Answers
Answer:
The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.
Explanation:
Answer:
They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.

The balanced chemical equation of decomposition of silver oxide is 2 Ag₂O -> 4 Ag + O₂.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
