Answer:

The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber

Explanation:

A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.

the combustion of octane is given in this reaction 2C8H18+2502-----16CO2+18H2 O, identify the limit reagent for this reaction wi

Archy [21]

Answer:

Liming reagent in the given reaction is oxygen.

Explanation:

Mass of octane = 12.85 g

Mass of oxygen = 7.46 g

Molar mass of octane = 114.23 g/mol

Molar mass of oxygen = 32

$Mole=\frac{Mass\;in\;g}{Molar\;mass}$

$No.\;of\;moles\;of\;octane=\frac{12.85}{114.23} = 0.1125\;mol$

$No.\;of\;moles\;of\;oxygen=\frac{7.46}{32} = 0.2331\;mol$

$2C_8H_{18} + 25O_2 \rightarrow 16CO_2 +18H_2O$

According to the reaction, 2 moles of octane requires 25 moles of O2

so, 0.1125 moles of octane requires $0.1125\times \frac{25}{2} = 1.40625\;mol$ of oxygen.

but only 0.2331 mol of oxygen is present.

Hence, oxygen is the limiting reagent
