Given a 0.5 M stock solution of aqueous NaCl, how much of the stock solution would you need to make a 50 mL sample of 0.25 M aqueous NaCl solution? How much water would you need to add to the NaCl solution?
Answers
Answer:
25 ml of stock
Explanation:
Molarity x Volume of Concentrated Stock = Molarity x Volume of Diluted Stock
=> Mc x Vc = Md x Vd => (0.5M)(x) = (0.25M)(50 ml)
=> x = Vc = (0.25M x 50 ml) / (0.50M) = 25 ml of stock

Explanation:
An environmental chemist analyzed the effluent (the released waste material) from an industrial process known to produce the compounds carbon tetrachloride (CC14) and benzoic acid (HC7H5O2), a weak acid that has one acidic hydrogen atom per molecule. A sample of this effluent weighing 0.3518 g was shaken with water, and the resulting aqueous solution required 10.59 mL of 0.1546 M NaOH for neutralization. Calculate the mass percent of HC7H5O2 in the original sample.
Answers
The mass percent of benzoic acid in the sample is 55.5%.
The equation of the reaction is; HC7H5O2(aq) + NaOH(aq) ----> NaC7H5O2(aq) + H2O(l)
Number of moles of NaOH reacted = concentration × volume
Number of moles of NaOH reacted = 10.59/1000 L × 0.1546 M
Number of moles of NaOH reacted = 0.0016 moles of NaOH
Since the reaction is 1:1, 0.0016 moles of HC7H5O2 reacted also.
Hence, mass of HC7H5O2 = 0.0016 moles × 122 g/mol = 0.1952 g
Mass percent of HC7H5O2 in the original sample = 0.1952 g/ 0.3518 g × 100 = 55.5%

Arctic foxes grow new fur with different seasons. They grow brown fur in the summer and white fur in the winter. These changes are examples of which survival characteristic?
adaptation
hibernation
metamorphosis
migration
Answers
Answer:
Adaptation.
Explanation:
The survival characteristic adopted by Arctic foxes during different seasons is called adaptation.
The term adaptation is used to define any behavioral or physical characteristics adopted by animals to help them survive their environment. The survival characteristics in the animal can be categorized into three domains: body parts, body coverings, and behaviors. In Arctic foxes, we see body coverings survival characteristics.
