Aluminum has chemical propertied that are similar to magnesium. What observation might you expect with the addition of 6M HCl to an aluminum strip? Explain.
An unknown salt is either NaF, NaCl or NaOCl.When 0.050 mol of the salt is dissolved in water for form 0.500 L of solution, the pH of the solution is 8.08. What is the identity of the salt?
What was the chemical reaction in the body, and what substance in the liver was produced to help catalyze the reaction?
A chemist prepares a sample of hydrogen bromide and finds that it occupies 252 mL at 70C and 464 Torr. What volume would it occupy at 0C at the same pressure.
what is the volume in milliliters of 20.0 g of acetone if the density of acetone is .791 g/ml?
Calculate the pH of a solution containing 0.085 M nitrous acid (HNO2; Ka= 4.4 × 10-4) and 0.10 M potassium nitrite (KNO2).
Have you observed that when you spill water over your skin on a hot day it will cool you down but if you spill vegetable oil in place of water it will not cool you down give explanation for this difference?
An 8 g of SO3 was placed in an evacuated container where it decomposed at 600 degrees Celsius. At equilibrium, the total pressure and density were 1.8 ATM and 1.6 g/L. Calculate constant pressure.
Suppose that Mt=Lt=0.1M (exactly) and the pH is somehow fixed at 5.00. (This means that the charge balance no longer applies.) Use the equilibria and the two mass balances to find the concentrations of ML+, M+2, L-, HL.
Compute the mass of Trisodium phosphate required to remove all Ca^2+ ions from 2.50 Litres of the H 2 O sample?
Use any other reagents that you need. Hint: you may first want to conduct some chemistry on each alkene first, then use the resulting products to make 1-decanol.
from the IR, 1H NMR spectrum and uv values decide what functional groups are present in the compound and deduce any other structural information you can, such as existance of conjugation in the carbonyl compound.
What is the pH of a buffer prepared by adding 0.809 mol of the weak acid HA to 0.406 mol of NaA in 2.00L of solution? The dissociation constant of is 5.66*10-7
