When 2 grams of carbon dioxide occupy a volume of 4.0 L. If the pressure and temperature do not change, how many more grams are needed make the volume 5.0 L? W

0.5 more Grams is needed to make 5.0 L.

Step-by-step explanation:

Half of 4.0 L needs 2 grams. With the volume now changing to 5.0 L to get there you'll add 0.5 + 2 grams to have 2.5 grams = 5.0 L.

just needed some points but try socratic

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
