The correct answer would be C2H60
From the periodic table:
molar mass of Sn = 118.71 grams
molar mass of F = 18.99 grams
This means that:
molar mass of SnF2 = 118.71 + 2(18.99) = 156.69 grams
Therefore, 156.69 grams of SnF2 contains 37.98 grams of F. To know the amount of F in 36.5 grams of the compound, we will simply do a cross multiplication as follows:
mass of F = (36.6 x 37.98) / 156.69 = 8.847 grams
Answer: For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. Burning lithium metal produces lithium oxide. Lithium oxide is produced by the thermal decomposition of lithium peroxide at 300-400°C.

Answer:</h3>
322.7 kW
<h3>
Explanation:</h3>
- Power refers to the rate at which work is done.
- Therefore; Power = Work done ÷ time
- It is measured in joules per seconds or Watts
In this case, we are required to convert 0.3227 MW to kilowatts
We need to know that;
- 10^6 watts = 1 Megawatts(MW)
- 10^3 Watts = 1 kilowatts (kW)
Therefore;
10^3 kW = 1 MW
Therefore, the suitable conversion factor is 10^3kW/MW
Hence;
0.3227 MW is equivalent to;
= 0.3227 MW × 10^3kW/MW
= 322.7 kW
Thus, the peak power output is 322.7 kW
When the charged balloon is brought near the wall, it repels some of the negatively charged electrons in that part of the wall. Therefore, that part of the wall is left repelled.
<u>Explanation</u>:
- Balloons don't stick to walls. However, if you rub the balloon on an appropriate piece of material such as clothing or a wall, electrons are pulled from the other material to the balloon.
- The balloon now as more electrons than normal and therefore has an overall negative charge. Two balloons like this will repel each other.
- The other material now has an overall positive charge. Because opposite charges attract, the balloon will now appear to stick to the other material. If you didn't rub the balloon first, it's charge would be neutral and it wouldn't stick to the wall.
