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

Since its asking for just the reactant, you can ignore the whole left side. Now since its only asking for the reactant containing Nitrogen, you can ignore the NaHCO3 since it doesnt have nitrogen.
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.

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.
