Question- Until 200 yr ago, manufactured iron contained charcoal produced from freshly cut wood that was added during the smelting process. As a result of this practice, older samples of iron can be dated accurately using the carbon-14 method. An archaeologist found a cast iron specimen that she believed dated to the period between 480 and 221 BC in Hunan, China. Radiocarbon dating of the sample indicated a 24% reduction in carbon-14 content. Was the archaeologist correct?
I don't know how to reach these answers thus please show the steps, thank you!
It takes 30.80ml of hydrochloric acid to neutralize 16.20 liter of 0.150 molars of magnesium hydroxide. determine the molality of the acid
The mixture was stirred, causing all of the sample to dissolve. The excess HCl in the solution required 94.9 mL of 0.128 M NaOH for complete neutralization in a titration. What was the molecular formula of the white substance
Following is an example of a triprotic acid with pK values closer than 3 units, and pK3 less than 10. You have a 20.0 mL solution of the triprotic acid, H3A, with a concentration of 0.128 M, and are titrating it with a 0.250 M solution of NaOH.
Top prepare for this week's lab, you added a KCL solution , Devarda's alloy, and MgO to your soil sample in order to analyze for mineral nitrogen. Sketch a jar containing soil and indicate hoe the nitrogen is initially present in the soil.
Compound A is unchanged when treated with dilute base, but treatment of A with concentrated NaOH and heat gives a new compound B (C10H19N) that decolorizes Br2 in CCl4. Compound B is identical to the product obtained from the reaction sequence bel..
