According to collision theory, the rate of reaction depends on atoms colliding in the correct _________ with enough ________ for

kenny6666 [7]

Answer: orientation , energy , frequency

Explanation:

According to the collision theory , the number of collisions that take place per unit volume of the reaction mixture is called collision frequency. The effective collisions are ones which result into the formation of products.

Effective collisions depends on the following two factors:-

1. Orientation factor: The colliding molecules must have proper orientation at the time of collision to result into formation of products.

2. Energy factor: For collision to be effective, the colliding molecules must have energy more than a particular value called as threshold energy.

You are given a cube of lead that is 1.000 cm on each side. The density of lead is 11.35. How many atoms of lead are in the samp

aliya0001 [1]

11.35 g atoms of lead are in the sample.

What does density mean?

The density of an area refers to the quantity of things—which may include people, animals, plants, or objects—there are in it.
Divide the number of objects by the area's measurement to determine density.
A country's population density is calculated by dividing its total population by its area, expressed in square kilometers or miles.

We can calculate the volume of the cube by cubing the side of the cube.

Volume of cube = ( 1.000 cm)³

= 1.000 cm³

We can now determine the amount of lead in the cube by multiplying by the density. Because we know we have a 1.000 cubic centimeter and that lead has a density of 11.35 grams per cubic centimeter, we have 11.35 grams of lead.

= ( 1.000 cm³) ( 11.35 $\frac{g}{cm^{3} }$ )

= 11.35 g

A fuel tank holds 22.3 gallons of gasoline. If the density is 0.8206 g/mL, what is the mass in kilograms of gasoline in a full t

7nadin3 [17]

Answer:

$m=69.3kg$

Explanation:

Hello!

In this case, since the density is computed by dividing the mass of the substance by its occupied volume (d=m/V), we first need to realize that 0.8206 g/mL is the same to 0.8206 kg/L, which means we first need to compute the volume in L:

$V=22.3gal*\frac{3.78541L}{1gal}=84.415L$

Then, solving for the mass in d=m/V, we get m=d*V and therefore the mass of gasoline in that full tank turns out:

$m=0.8206g/L*84.415L\\\\m=69.3kg$

Best regards!
