HELP MEEEE!!!!!!!!!!!!!!!!!!!! I will give brainliest to whoever answers correctly first.

Another statement is, "Volume is directly proportional to the number of moles."

The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.

V

∝

n

, where

V

is the volume, and

n

is the number of moles.

V

n

=

k

, where

k

is a proportionality constant.

We can rewrite this as

V

n

=

V

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.

STP is 0 °C and 1 bar.

One mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L

Example Problem

A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

Solution

The formula for Avogadro's law is:

Answer:

"Let the smaller value a = 10 and the larger value b = 100. Than a^2 + 2ab + b^2 is 10^2 + 2 * 10 * 100 + 100^2. This can be simplified to 12100. So, 110^2 is equal to 12100."

Hope this helped!

The smaller value is 10

The larger value is 100

So the square of 110 should be 12100

Since here we assume the smaller value be 10

So, the larger value be 100

Now

[tex]a^2 + 2ab + b^2 = 10^2 + 2 \times 10 \times 100 + 100^2.[/tex]

This can be simplified to 12100.

So, [tex]110^2[/tex] is equal to 12100.

Answer:

x = - 5, x = - 1

Step-by-step explanation:

Given

(x + 3)² = 4 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 3 from both sides )

x = - 3 ± 2

Then

x = - 3 - 2 = - 5

x = - 3 + 2 = - 1

Answer:

1.5 per hour : 1.2 per hour

Step-by-step explanation:

The computation of the ratio is shown below:

For norma, the one pool would be

= 12  pools ÷ 8 hours

= 1.5 per hour

And for albert, the one pool would be

= 9 pools ÷ 7.5 hours

= 1.2 per hour

So the ratio between them is

1.5 per hour : 1.2 per hour

Answer:

64.428

Step-by-step explanation:

well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence

so if we add all of the numbers up it will give us

451

then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with

around 65 or exactly it would be

Answer:

42,42,96

Step-by-step explanation:

The angles of each plane that must be cut to fit are 42°, 42°, and 96°.

The dimension of each plane is 13.4 ft, 13.5 ft, and 20 ft.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Two angles of the figure are:

96 and 42.

The sum of the angles in a triangle is 180°.

So,

The other angle.

= 180 - (96 + 42)

= 180 - 138

= 42

Now,

The angles of each plane must be cut in 42°, 42°, and 96°.

Now,

The side opposite to the equal angles is equal.

So,

The dimensions of the triangles are 40.5 ft, 40.5 ft, and 60 ft.

The dimensions of each plane.

= 40.5/3,  40.5/3, and 60/3

= 13.4 ft, 13.5 ft, and 20 ft.

Thus,

The angles of each plane are 42°, 42°, and 96°.

The dimension of each plane is 13.4 ft, 13.5 ft, and 20 ft.
