Answer:

f(2)= 11

Step-by-step explanation:

you have to substitute 2 for every x you see:

                       f(x) = 3x² + 2x - 5

                       f(2)= 3(2)^2+2(2)-5

                       f(2)= 11

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.

marysya [2.9K]
'Pi' ( π ) is the ratio of the circumference of a circle to its diameter.

The exact value of 'pi' can't be completely written with numbers, so whenever
we use 'pi', we always use an approximation.
