Gallium arsenide has a zinc blende crystal structure. Assume a lattice constant
of a = 5.65 Å. Determine the density of gallium arsenide in g/cm3.
What factors influence chelating activity?
You have gotten a call from one of the tenants of your rental house. He stated that some of the following parts needed immediate maintenance and pictures of those parts were attached as follows. Discuss the factors that cause limescale effect to occur and state the appropriate treatment method used to eliminate the effect.
Transition of metal-to-ligand charge transfer (MLCT) results in the oxidation of the metal.
Strong field ligands able to increase the magnitude of splitting energy in an octahedral transition metal complexes via -acceptor interaction.
Analyse the symmetry elements possessed by carbonate and hydronium ions. List the symmetry elements that both ions have in common.
A crystalline solid is composed of the elements 'A' and 'B.' A atoms are present at the corners, while B atoms are present at the face centers. However, one atom of A is missing from one of the corner points. What type of crystal defect is this, and how does it happen? What happens to the density of this solid material?
Spills from the industry was sent to your laboratory for analysis to determine the contents of the spill. Your laboratory did not have a sophisticated instrument running the analysis and the authority of the region want the results immediately. The spillage content of element group 1 and 2. You have run a sample experiment to identify that element. Describe the method you will use to identify the element.
Explain why chlorine is used in the purification of water.
A water sample B has a turbidity reading of 50 NTU. If a 50-ppm standard has a turbidity reading of 100 NTU, what is the concentration of the analyte in A that causes the water to be turbid?
