(a) Give the names and chemical symbols for the three isotopes of hydrogen.
(b) List the isotopes in order of decreasing natural abundance.
(c)Which hydrogen isotope is radioactive?
(d)Write the nuclear equation for the radioactive decay of this isotope.
Ferrocene cannot be nitrated using the conventional HNO3-H2SO4 mixed acid conditions, even though nitration is an electrrophilic aromatic substitution reaction. Explain.
How many moles of each ion are in each solution? (a) 2 mol of potassium perchlorate dissolved in water K+ mol ClO4- mol (b) 255 g of magnesium acetate dissolved in water Mg2+ mol C2H3O2- mol
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
A sample of a gas weighs 2.006 g and has a volume of 1060.0 mL at 795.0 torr and 32.0 degrees Celsius. What is its molar mass?
A 0.1500 g sample of pure ZnCl2xnH20 was placed on an ion-exchange column in the H+ form. The H+ released in the eluate required 16.98 mL of 0.1024 M NaOH to reach a phenolphtalein end point. Calculate the percent zinc in the sample.

what would be the vapor pressure at 25.0 degc of a solution of 5.00 g of glucose c6h12o6 in 100.0 g of ethanol c2h5oh?
An aqueous solution of an unknown ruthenium salt is electrolyzed by a current of 2.50 A passing for 50.0 minutes. If 2.618 g Ru is produced at the cathode, what is the charge of the ruthenium ions in solution
A certain quantum mechanical system (NOT the hydrogen atom) has the energy levels shown in the diagram below. The energy levels are indexed by a single quantum number n that is an integer.
A 26.0 mL aliquot of a flouride sample solution was diluted to 50 mL in a volumetric flask. The F- concentration of this DILUTED sample was determined with a F- ion selective electrode and found to be 3.1 mg/L. What is the concentration of F- in t..
