1000 liters = 1 m^3
and
1.3um^3 = 1.3x10^(-6)m^3
multiply both sides of the first equation by 1.3x10^(-6)
1.3x10^(-6) * 1000 liters = 1.3x10^(-6) * 1m^3
1.3x10^(-3) liters = 1.3x10^(-6) m^3
Answer: D : A is 3 : 2.
Explanation:
The law of definite proportion is being used here. The law states that a given compound always has the same proportion of its constituent elements by mass.
2a + b = c + 3d
This actually means that, two moles of “a” react with a mole of “b” to produce a mole of “c” and 3 moles of “d”
Using the concept of stoichiometry coefficients of d and a
d:a = 3:2
I BELIEVE THAT VAPORIZATION THAT <span>element or compound is a phase transition from the liquid phase to vapor.
AND
EVAPORATION </span>a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.
The balanced chemical
reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of propane gas to be burned. This will be
our starting point.
<span>38.95 </span><span>g C3H8 ( 1 mol C3H8 / 44.1 g C3H8 ) ( 5 mol O2/1
mol C3H8)(32 g O2 / 1 mol O2) =141.32 g O2
Therefore, the reaction consumes approximately 142 grams of oxygen gas.</span>
Answer:
Fastest C. Reaction time is faster
Slowest A. Reaction time is slower and it takes longer to finish
