1. The option a. 10 mL has the most uncertainty associated with it, because it has only 2 significative figures, while 10.0 mL has three significant figures and 10.00 has four significant figures.
2. The volume of solution that remains is 145.675 mL - 24.2 mL = 121.475 mL rounded to one decimal = 121.5 mL, given that the measure with the most uncerntainty has only one decimal.
Answer:
Reaction products are shown below
Explanation:
- In cannizaro reaction, benzaldehyde produces benzoic acid and benzyl alcohol through disproportion.
- Here, a hydroxyl group first gives a nucleophilc addition at carbonyl center of benzaldehyde.
- Then a hydride transfer takes place to another molecule of benzaldehyde
- Thus, benzoic acid and benzyl alcohol are produced.
- Full reaction mechanism has been shown below
U need positive and negative electordoe and an electrolyte <span />
I think it means the reaction doesn't have any intermediate phases - the order doesn't change, and it moves at the same rate, it doesn't speed up or slow down at any time
Answer:
Periodic Law.
Explanation:
The Periodic Law states that the physical and chemical properties of the elements repeat in a systematic and predictable way when the elements are arranged in order of increasing atomic number.
Many of the properties are repeated at intervals.
When the elements are arranged correctly, the trends in element properties become apparent and can be used to make predictions about unknown or unfamiliar elements, simply based on their placement on the table.
