Answer:
Yes, it can be extracted through evaporation. It retains its original properties.
Explanation:
i took the test.
Answer: The final concentration is 0.16 M.
Explanation:
According to the dilution law:
where,
= molarity of stock solution = 1.60 M
= volume of stock solution = 54.0 ml
= molarity of diluted solution = ?
= volume of diluted solution = 218 ml
Putting these values:
Now 109 ml of this diluted solution is further diluted by adding 161 mL of water.
Again applying dilution law:
Thus the final concentration is 0.16 M
Answer:
Thorium-234 option a .......
Answer:
Option (3) is the correct answer.
Explanation:
Answer:
54.075KJ
Explanation:
Since methane is the limiting reactant.
From the reaction equation,
16 g of methane absorbs 206 KJ of energy
4.20 g of methane will absorb 4.20 × 206/16 = 54.075KJ of energy was absorbed.
From the equation, the value of the enthalpy of reaction is positive, this means that energy is absorbed in the reaction of methane and water. Hence the answer.
