Significant Figures: How many significant figures<br> are in 865,010?
Harrizon [31]

Answer: There are five significant figures in 865,010.

Explanation:

When a degree of accuracy is stated by each digit present in a mathematical figure then it is called a significant figure.

Rules for counting significant figures is as follows.

  • Any non-zero digits and zeros present between a non-zero figure are counted. For example, 3580009 has seven significant figures.
  • Trailing zeros are counted in a non-zero figure. For example, 0.00250 has three significant figures.
  • Leading zeros are not counted. For example, 0.0025 has two significant figures.

So, in the given figure 865010 has five significant figures and the trailing zero will not be counted.

Thus, we can conclude that there are five significant figures in 865,010.

Two steps in a synthesis of the analgesic ibuprofen include a carbonyl condensation reaction, followed by an alkylation reaction
Tresset [83]
Ibuprofen is synthesized by reacting ethyl 2-(4-isobutylphenyl)acetate with base, the base abstracts the acidic proton and enolate is formed which on reaction with diethyl carbonate generates diethyl 2-(4-isobutylphenyl)malonate (A). diethyl 2-(4-isobutylphenyl)malonate on treatment with Base again looses the acidic proton and forms enolate. The enolate with treatment with Methyl Iodide yields diethyl 2-(4-isobutylphenyl)-2-methylmalonate (B). diethyl 2-(4-isobutylphenyl)-2-methylmalonate on hydrolysis give Ibuprofen.

Ca(OH)2 is added to a large beaker. How is the solution different from the original water?
shepuryov [24]
Definitely, the correct answer is option B. When Ca(OH)2 is added into a beaker, the solution will turn into pink when the indicator phenolphthalein is added. This is due to the hydroxide ions from the calcium hydroxide dissolved in water. The compound dissociates into calcium ions and hydroxide ions.
