According to the Kinetic Molecular Theory, as the volume of a gas increases: the number of particle impacts per unit area increa

aliya0001 [1]

As the volume of a gas increases at constant temperature, the number of particle impacts per unit area decreases.

There is the same number of impacts, but they are spread over a larger surface area.

Thus, the number of impacts per unit area decreases.

A crow flies 100 meters east in 5 minutes. What is the crow’s velocity?

torisob [31]

Answer: 20 m/min east

Explanation: The speed is distance divided by time

distance between start-point and end-point = 100 meters

time to cover the distance = 5 minutes

100 m ÷ 5 min = 20 m/min east

you have to add east since velocity is the measure of speed and direction and your answer needs to include the direction

Physical science!!! please help

Answer:

The correct answer is : No, because there are 4 hydrogen atoms on the reactants side and 2 on the products side.

Explanation:

$NH_4NO_3\rightarrow N_2O+H_2O$

The given reaction equation is not balanced because:

Number of hydrogen atoms on both sides are not equal that is 4 on reactants side and 2 on products side.
Number of oxygen atoms on both sides are not equal that is 3 on reactants side and 2 on products side.

In a balanced chemical equation number of atoms of each elements are equal on both sides.

So, the balanced chemical equation will be:

$NH_4NO_3\rightarrow N_2O+2H_2O$
