From 2010-2022, what are the developments of analytical chemistry. Discuss in chronological order.


the 5 g of zinc powder used is an excess. Calculate the mass of zinc that reacts exactly with 50.0cm3 of 1.00 mol dm


Use the balanced chemical equation for the neutralization of hydrochloric acid with calcium hydroxide to determine the concentration of the hydroxide ion, in moles per litre. (Hint: why does one not need to know the volume of one drop?) From [OH-], determine [Ca2+] in moles per litre.

How many aluminium ions will be discharged by 0.33F?[Avogadro constant = 6.02*10^23


Determine the mass of nitrogen found in 8.85g of Pb(NO3)3


Find the mass in grams of 2.00 x 10^23 molecules of F2


Hilda, Layla, and Saber were experimenting with a carbon steel rod in the chemistry laboratory. Hilda learned that the carbon steel has a strain hardening ratio of 0.841, yet it breaks at a force of 45 N. Layla and Saber calculated the 15 mm2 rod's yield limit. The information they got was lacking because they have failed to borrow an SEM, but they were able to calculate the spacing of the atoms. Determine the spacing of the atoms if the shear modulus is 0.3 GPa and the interatomic space is equal to 1.8 Å.
