What is the slope of the line?

Answer: Electrons have wavelike motion and are restricted to certain energy states associated with specific wavelengths.

Answer:

For balancing this equation

we need to put

Ag2O. = 2

Ag = 4

O2 = 1

Hope it will help

The balanced chemical equation of decomposition of silver oxide is 2 Ag₂O -> 4 Ag + O₂.

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.

Explanation:

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.

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.

Answer:

A

Explanation:

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.
