Answer:
15.9 g
Explanation:
(Take the atomic mass of C=12.0, H=1.0, O=16.0)
no. of moles = mass / molar mass
no. of moles of octane used = 11.2 / (12.0x8 + 1x18)
= 0.0982456 mol
Since oxygen is in excess and octane is the limiting reagent, the no. of moles of H2O depends on the no. of moles of octane used.
From the balanced equation, the mole ratio of octane : water = 2:18 = 1: 9,
so this means, one mole of octane produced 9 moles of water.
Using this ratio, we can deduce that (y is the no. of moles of water produced):
y = 0.0982456x9
y= 0.88421 mol
Since mass = no. of moles x molar mass,
mass of water produced = 0.88421 x (1.0x2+16.0)
=15.9 g
Cells have many structure inside of them called organelles which allow it to function and survive
Hope it helps

Atomic mass for Osmium tetroxide would be 254.23 g/ml
Answer: Option (C) is the correct answer.
Explanation:
Biopower means production of electricity with the help of biomass. The unused wood, crops, agricultural residue, animal residue etc when burned then they help in generating biopower.
It is a renewable energy. Since biomass is readily available in most of the places. Therefore, the advantage of biopower is that it is also readily available in most places.
For example, bacterial decay produces a certain amount of heat which further helps in the production of energy.
Yes; you need to know how long the light bulb is on.
<h3>How much electricity does a light bulb use?</h3>
Because of this, lower wattage bulbs are sometimes referred to as "equivalent to 60W"; nevertheless, what is equal is brightness, not energy consumption.
Converting wattage to kilowatts is the best way to determine how much energy your lightbulb consumes. Thus, 0.1 kW would be needed per hour for a 100W light bulb.
Incandescent (up to 100W) and halogen (up to 120W) light bulbs with higher energy consumption are being phased out. You may get ornamental exposed carbon filament light bulbs, which are normally 40–60W, if you still have any of them operating in your house.
