Answer:
8.29 mL
Explanation:
Density of acetone in g/mL = 0.791 g/ml
Dimensional analysis: 6.56 g x (1 mL/0.791 g) = 8.29 mL
Answer: Elements in the same column are similar in their properties
Explanation: The columns on the periodic table are also know as group of the periodic table elements in the same group of the periodic table tends to have similar chemical properties because they all have the same number of valence electrons in their outermost shell. This plays an important roles in their reactivity and properties
Because negatives are on the left and positives are on the right , if it was .0100 +x it would move to the right since +x implies that the x is positive.
Answer:
89.4%
Explanation:
Initially, there is 5.0 of the acetanilide in 100 mL of water, then the solution is chilled at 0ºC. The solubility represents the amount that the solvent (water) can dissolve of the solute (acetanilide). So, at 0ºC, 100 mL of water can dissolve till 0.53 g of the compound, the rest will precipitate and will be recovered.
So, the mass that is recovered is 5.0 - 0.53 = 4.47 g
The percent recovery is:
(4.47/5)x100% = 89.4%
