In acidic solution, the bromate ion can be used to react with a number of metal ions. One such reaction is
\rm \rm {BrO_3}^-{(aq)}+Sn^{2+}{(aq)}\rightarrow \rm Br^-{(aq)}+Sn^{4+}{(aq)}Since this reaction takes place in acidic solution, \rm H_2O{(l)} and \rm H^+{(aq)} will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation
How many grams of water can be cooled from 45 C to 23 C by the evaporation of 63 of water? (The heat of vaporization of water in this temperature range is 2.4 kJ/g . The specific heat of water is 4.18 J/g*K .)
Uric acid dissociates as shown in the figure at the right with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range.
Calculate the quantity of energy produced per gram of reactant for the fusion of H-3 (atomic mass = 3.016049 amu) with H-1 (atomic mass =1.007825 amu) to form He-4
Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs.
Complete and balance the following redox equation using the smallest whole-number coefficients. Show the steps. Sn (s) + HNO3 --> SnO2 (s) + NO2 + H2O (not balanced, assume acidic solution)
A graduated cylinder contains 20.5 mL of water. What is the new water level after 27.3 g of silver metal with a density
Determine the pH of the acid solution before the titration begins and the pH at the equivalence point when 50.0 mL of the NaOH has been added. The Ka of HF is 7.2*10^-4
A solution is prepared by mixing 13.00ml of 0.0021M (aq) Hg2(NO3)2 with 25.0ml of 0.015M HCl. Assume that volumes are additive.
Discuss how to prepare the soltion starting from 0.100 M formic acid and 0.150 M sodium formate
a batch of 1000 kg of KCl is dissolved in sufficient water to make a saturated solution at 363K, where the solubility is 35 wt% KCl in water. the solution is cooled to 293K, at which the solubility of KCl is 25.4 wt%.
One of the students in lab decided to use two fractionating columns (one on top of the other) instead of just one. How would this a) affect the separation between hexane and heptane?
What is the temperature of 0.600 mol of gas at a pressure of 1.5 atm and a volume of 12.1 L
