1st energy level can hold 2 electrons
2nd energy level can hold 8 electrons
3rd energy level can hold 8 or 18 electrons
Chemical properties can be determined by heat combustion, how they react with other chemicals, Oxidization (lose electrons, losing hydrogen, gaining oxygen), or toxicity.
Answer:
151200 minutes.
Explanation:
From the question given above, the following data were obtained:
Time (in week) = 15 weeks
Time (in min) =?
Next, we shall convert 15 weeks to days. This can be obtained as follow:
1 week = 7 days
Therefore,
15 weeks = 15 weeks × 7 days / 1 week
15 weeks = 105 days
Next, we shall convert 105 days to hours. This can be obtained as follow:
1 day = 24 h
Therefore,
105 days = 105 days × 24 h / 1 day
105 days = 2520 h
Finally, we shall convert 2520 h to mins. This can be obtained as follow:
1 h = 60 mins
Therefore,
2520 h = 2520 h × 60 mins / 1 h
2520 h = 151200 mins
Thus, 15 weeks is equivalent to 151200 minutes.
There's a lot of things built from petroleum, such as toothpaste.
Here's also another list.Gasoline 46%
Heating Oil / Diesel Fuel 20%
Jet Fuel ( kerosene) 8%
Propane / Propylene 7%
NGL / LRG 6%
Still Gas 4%
Petrochemical Feedstocks 2%
Petroleum Coke 2%
Residual / Heavy Fuel Oil 2%
Asphalt / Road Oil 2%
Lubricants 1%
Miscellaneous Products / Special Naphthas 0.4%
Other Liquids 1%
Aviation Gasoline 0.1%
Waxes 0.04%
Kerosene 0.02%
This process is called evaporation as I believe
