Can someone help me solve this matrix

Answer:

12

Step-by-step explanation:

Least common multiple of the numbers 2, 3, and 4 is 12

Answer:

3

Step-by-step explanation:

For them to at least be a whole number, it’s 3

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

n

2

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:

V

Answer:Average speed =50 miles per hour or 50mph

Step-by-step explanation:

We know that  Speed is given as= Distance/ Time

Nimer's  distance to his destination = 65 miles

Time taken to his destination = 13:30 to  14:48

which is = 14:48--13:30 = 1:18 mins

Converting  1hr 18mins  to hours = 1 hour + 18/ 60 = 1 + 0.3 = 1.3 hours

Average speed =Distance/ Time

Average speed = 65miles/ 1.3hr = 50 miles per hour

Answer: It will cost $196

245 ÷ 10 = $24.5

$24.5 x 8 = $196

Hope this helps, have a wonderful day!

Answer:

False

Step-by-step explanation:

5-2(3-x) =

3(3-x) = (not sure about this step)

9-x, this answer does not equal 4x + 10

Answer: The numbers go from left to right on the table in this order: 0, 3, 4, 3, 0, -5.

To do the problem, you put the x - value in place of where the x is in the equation above (y = 4 - x^2) and then you put what y equals in the box after you finish.

Good luck, hope this helped!!

Answer:

3(2x + 5)

Step-by-step explanation:

What numbers go into both 6 and 15? What number is the largest of those numbers? The answer to both questions is 3, therefore we factor out the 3 using the distributive property

Answer:

It is 3(2x+5)

Hope you get it right

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, but I would show you how to answer it.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Reflection is the flipping of a figure about an axis. Reflection is a rigid transformation, that is it preserves the shape and size of the figure.

If the distance between Line segment t and line segment r is 5 units and then both line segments are reflected across the y–axis to form line segments t' and r'. The distance between the newly formed line segments t' and r' would still be 5 units
