If two protons are added to carbon, the chemical identity changes to oxygen, which is two spaces over horizontally on the periodic table. The number of protons is what we call the atomic number (Z), and this is what defines the identity of an element. Since we also added two neutrons, this is simply oxygen, or oxygen-16, the most abundant isotope of oxygen.
Mg3N2 + 6H2O => 3Mg(OH)2 + 2NH3
100 mL graduated cylinder because the device is more precise.
<u>Answer: </u> of volume needs to be pipetted out in the test tube.
<u>Explanation:</u>
We are given:
Mass of BSA to be formed = (Conversion factor:
Volume of stock solution = (Conversion factor:
It is also given that for the mass of BSA is 0.5 g, the volume used up is 1 mL
In order to have, 0.005 g, the volume of stock solution needed will be =
Hence, of volume needs to be pipetted out in the test tube.
