Answer:

25 : 18

Explanation:

Mole ratio:

It is simply the ratio between moles of any two compounds take part in chemical reaction. It gives the proportion of compounds present.

The given reaction is the burning of octane. Two moles of octane burned in the presence of twenty five moles of oxygen and produced sixteen moles of carbon dioxide and eighteen moles of water.

Chemical equation:

C₈H₁₈ + O₂     →     CO₂ +  H₂O

Balance chemical equation:

2C₈H₁₈ + 25O₂     →     16CO₂ + 18H₂O

The mole ratio of oxygen and water is 25 : 18.

What property of a liquid is used when petrol, ( gasoline) is pumped from the tank to the engine of a car? I need answers!!!!
Romashka-Z-Leto [24]
In many modern cars the fuel pump is usually electric and located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine. The higher gasoline pressure raises the boiling point.

If an object has a temperature of 0 kelvin, how much energy is the object emitting? what is the wavelength of light emission acc
NNADVOKAT [17]

This law (expressed mathematically as E = σT4) states that each gadget with temperatures above absolute zero (0K or -273°C or -459°F) emits radiation at a charge proportional to the fourth energy in their absolute temperature.

Wien's displacement law states that the black body radiation curve for one-of-a-kind temperatures height at a wavelength is inversely proportional to temperature.

Wien's displacement law It states that the better the temperature, the lower the wavelength λmax for which the radiation curve reaches its most. The shift to shorter wavelengths corresponds to photons of better energies. In other phrases, λmax (height wavelength) is inversely proportional to temperature.

Wien's regulation, named after the German Physicist Wilhelm Wien, tells us that gadgets of different temperatures emit spectra that height at distinctive wavelengths. hotter objects emit radiations of shorter wavelengths and for this reason, they seem blue.

Wien's regulation tells us that gadgets of various temperatures emit spectra that top at specific wavelengths. hotter gadgets emit a maximum of their radiation at shorter wavelengths; subsequently, they will seem like bluer. Cooler gadgets emit most of their radiation at longer wavelengths; consequently, they'll appear redder.
