Answer:
Explanation:
2S + 3O₂ = 2SO₃
2moles 3 moles
2 moles of S react with 3 moles of O₂
5 moles of S will react with 3 x 5 / 2 moles of O₂
= 7.5 moles of O₂ .
O₂ remaining unreacted = 10 - 7.5 = 2.5 moles .
All the moles of S will exhausted in the reaction and 2.5 moles of oxygen will be left .
Answer:
295.7 mL of 24% trichloroacetic acid (tca) is needed .
Explanation:
Let the volume of 24% trichloroacetic acid solution be x
Volume of required 10% trichloroacetic acid solution =8 bottles of 3 ounces
= 24 ounces = 709.68 mL
(1 ounces = 29.57 mL)
Amount of trichloroacetic acid in 24% solution of x volume of solution will be equal to amount of trichloroacetic acid in 10% solution of volume 709.68 mL.
x = 295.7 mL
295.7 mL of 24% trichloroacetic acid (tca) is needed .
That would be either, nuclear power or wind power, depending on what the teacher is looking for...
Boiling I think! hope you get it right
Your answer is, all of the above.
<u>Chemical Change </u>
A chemical change occurs on the molecular level and produces a new substance. However, a physical change rearranges molecules and does not produce a new substance.
<u>10 examples of chemical changes</u>
- Burning of paper and log of wood
- Various metabolic reactions that take place in the cells
<u> Impacts of Chemical changes</u>
Anytime a new substance is made, a chemical change takes place. Usually two or more materials are combined and a new substance is formed. A chemical change can produce amazing explosions, like fireworks.
Thus, <u>all of the above</u> is the correct answer. Learn more about "Chemical Changes" here
