Answer:
x=2.8moles
Explanation:
first step balance the chemical equation
C2H6+O2-->CO2+2H2O
use more ratio to find the moles of water
1mole of C2H6= 2 moles of H2O
1.4mole of C2H6=?x
cross multiply
x=2.8 moles of H2O

Answer:
Option (A) the solid X is ground to a fine powder.
Explanation:
X(s) + 2B(aq) → X+(aq) + B2(g)
In the reaction above, the rate of the reaction will be highest, when X being a solid is ground to fine powder.
Grounding X to fine powder simply means increasing the surface area of X.
An increase in surface area of reactants will definitely increase the rate of reaction because the particles of the solid will collide with the right orientation and hence speed up the reaction rate.
