Explain how specifically a living molecule was supposed to have formed from an organic substance.
According to the Bible, life started when God spoke it into existence. Are there any flaws with the theory that life came from organic compounds?
Pick one molecule and describe how scientists theorize it formed.
Depict the complete 3-step mechanism for the hydroboration of 1-octene this means drawing out the three repetitive steps to obtain the trialkyl borane. Comprise arrows indicating electron flow as well as identify any R groups if you use shorthand.
A 8.05-L container holds a mixture of two gases at 39 degree Celsius. The partial pressure of gas A and gas B, respectively, are 0.178 atm and 0.894 atm. If 0.210 mol a third gas is added with no change in volume or temperature, what will the tota..

The overall reaction in the lead storage battery used in your car is Pb (s) + PbO2 (s) + 2 H+ (aq) + 2 HSO4 - (aq) ? 2 PbSO4 (s) + 2 H2O (l) a. For the overall cell reaction
Problem- List reasons why the theoretical pH value of the buffer you prepared was different from the experimental pH value.
When adding the solution of HNO3 from the buret in Step 14 to beaker 4, you know that you added 2.5 mL instead of 1.5 mL for a total volume of 11.0 mL. How would the calculated value of the equilibrium constant be affected for this sample?
High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa)
