Answer: 36 moles oxygen
Step-by-step explanation:
C10H8 + 12O2 ====》 10CO2 + 4H2O
From the equation of the reaction,
1 mole of napth requires 12 moles of O2
3 moles of napth would require x moles O2
X = (3 * 12) / 1
X = 36 moles of oxygen.
Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen
<em>Answer is 0.009 </em>
<em></em>
0.9 ( 0.01 m / cm ) = 0.009
Line of symmetry is the line which cuts the figure into two same halves
or we can say that which passes through the figure such that it makes one half the mirror image of the other half
So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves
So
y=-2
Third option
C. 7. because if you divide the value for the missing term (take 28 for example) and divided it by the value of i (4) you will get 7. (28÷4=7)
