Answer:
A. Heat the solution
Explanation:
To make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 mL of water at 80 degrees Celsius. When the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.
<u>1) balanced chemical equation</u>
<u>2) convert mass of CO₂ to moles</u>
<u>3) multiply by molar ratio</u>

<u />
4) convert moles of C₄H₁₀ to mass
= 23.7 grams of C₄H₁₀ is needed to produce 71.9 grams of CO₂
NaCl:
Na = + 1
Cl = - 1
hope this helps!
Reactants are carbon dioxide and water, the products are glucose and oxygen. Don't know for sure what the yield is represented with, so, I can't help you with that.
Answer:
20ppm
Explanation:
parts per million are defined as the mass of solute in mg (In this case, mass of DDT) per kg of sample.
To solve this question we must find the mass of DDT in mg and the mass of sample in kg:
<em>Mass DDT:</em>
0.10g * (1000mg / 1g) = 100mg
<em>Mass sample:</em>
5000g * (1kg / 1000g) = 5kg
Parts per Million:
100mg / 5kg =
<h3>20ppm</h3>
