Burning fossil fuels release a lot of carbon dioxide which is a greenhouse gas which contributes to global warming. Also burning of fossil fuels causes a lot of air pollution. You can also describe in detail the effect of carbon dioxide on global warming in general
The answer is D. KOH (potassium hydroxide)
In bulbs 93 percent Argon and 7 percent Nitrogen is filled because both these are generally heavy gases so they reduce transfer of heat between panels in bulb....
also both are colourless and dry gases....
pls give me a good rate cus i have no idea
Answer:
Explanation:
First we convert <u>the given masses of each element into moles</u>, using <em>their respective molar masses</em>:
- Fe ⇒ 11.26 g ÷ 55.845 g/mol = 0.202 mol Fe
- S ⇒ 9.70 g ÷ 32.065 g/mol = 0.302 mol S
Now we <em>divide them</em> in order to <u>calculate the molar ratio of S to Fe</u>:
Meaning that for each 1 Fe mol, there's 1.5 S moles. We can write that as Fe₁S₁.₅
Finally we <u>double those subscripts</u> so that <em>they become the lowest possible integers</em>: Fe₂S₃.
