Answer:
The acid-base reaction produces glycine reduction, and hence the increase of glycine pH.
Explanation:
The glycine is an amino acid with the following chemical formula:
NH₂CH₂COOH
The COOH functional group is what gives the acid properties in the molecule.
Hence, when NaOH is added to glycine an acid-base reaction takes place in which COOH reacts with the NaOH added:
NH₂CH₂COOH + OH⁻ ⇄ NH₂CH₂COO⁻ + H₂O
The glycine concentration starts to shift to its ion form (NH₂CH₂COO⁻) because of the reaction with NaOH, that is why the pH glycine increases when NaOH is added.
Therefore, the acid-base reaction produces glycine reduction, and hence the increase of glycine pH.

Answer: ³²P
Explanation:
The radionuclide in question is known as Phosphorus-32. It is an isotope of Phosphorus that is radioactive and has one more neutron than the normal phosphorus does.
Phosphorus does not exist in nature and is created artificially by bombarding the normal stable phosphorus with neutrons. Due to its radioactive nature, it has proven to be useful in the medical industry where it has been used to detect eye tumors as well as in treating some diseases.
Answer:
Volume of liquid = 28.7 mL
Explanation:
Given data;
Density of solid = 3.57 g/ml
Mass of solid = 19.5 g
Volume of water = 23.2 mL
Total volume when solid is dropped into graduated cylinder= ?
Solution:
Density = mass/ volume
v = m/d
v = 19.5 g/ 3.57 g/ml
v = 5.5 mL
Volume of liquid = volume of water + volume of solid
Volume of liquid = 23.2 mL + 5.5 mL
Volume of liquid = 28.7 mL
Answer:
I Think it might be A! I hope I am right!
