Answer:
Explanation:
Burning fossil fuels releases the carbon dioxide stored millions of years ago. ... The concentration of carbon dioxide in the atmosphere has increased more in the northern hemisphere where more fossil fuel burning occurs. Since the Industrial Revolution the concentration globally has increased by about 40 % .

Answer : Below are three ways described in brief for improving the quality of indigenous soap.
1) Add virgin coconut oil which serves as a softener and betel leaf extract. It is used to improve the quality of soap as an antimicrobial agent.
2) Add activated charcoal black granules or powder to the soap, it removes maximum dirt from the skin.
3) Adding a filler which will increase the shelf life of usage of the soap will also improve its quality.
For
the reaction 2SO2 + O2 -> 2 SO3, we first determine which is the excess
reactant between SO2 and O2. We list down the molar mass of the reactants:
Molar
mass of SO2 = 64.0638 g/mol
Molar
mass of O2 = 32 g/mol
Using
the stoichiometry of the reaction, we then calculate the amount of oxygen that
will react with 90.0 g of SO2.
90.0
g SO2 x 1 mol SO2/64.0638 g x 1 mol O2/ 2 mol SO2 x 32 g O2/mol = 22.4776 g O2
<span>
</span>
<span>Thus,
we can conclude that O2 is the excess reactant while SO2 is the limiting
reactant. Subtracting 22.4776 g O2 from the initial 100.0 g O2, we get 77.5224
g O2 left after the complete reaction of 90.0 g SO2. </span>
