Let five moles of oxygen are required to react with 2 moles of acetylene. So, doing a rule of three, we are going to obtain :
5 moles of Oxygen => 2 moles of C2H2
? O2 => 1 mole of C2H2
1.0 mole C2H2×(5 moles O2/2 moles of C2H2) = 2.5 moles of O2
So, the answer is <em><u>2</u></em><em><u>.</u></em><em><u>5</u></em><em><u> </u></em><em><u>m</u></em><em><u>o</u></em><em><u>l</u></em><em><u>e</u></em><em><u>s</u></em><em><u> </u></em><em><u>o</u></em><em><u>f</u></em><em><u> </u></em><em><u>o</u></em><em><u>x</u></em><em><u>y</u></em><em><u>g</u></em><em><u>e</u></em><em><u>n</u></em> are required to react with 1 mole of acetylene.
Step-by-step explanation:
the slope of a line is the factor of x, when the equating looks like
y = ...
so,
x - 3y = 3
x = 3y + 3
3y = x - 3
y = 1/3 x - 1
so, the original slope is 1/3.
a parallel line has the same slope.
having a specific point we can use the point-slope form as equation :
y - y1 = m(x - x1)
with m being the slope, and (x1, y1) being a point on the line.
y - -3 = 1/3(x - 2)
y + 3 = 1/3(x - 2)
simplified that is
y + 3 = 1/3 x - 2/3
y = 1/3 x - 2/3 - 3 = 1/3 x - 2/3 - 9/3 = 1/3 x - 11/3 =
= 1/3 × (x - 11)
I would add 4+6+8 but to make this easier i would maybe split them
