A pure titanium cube has an edge length of 2.68 . How many titanium atoms does it contain? Titanium has a density of 4.50 g/cm3
It takes 3.1 minutes for a 1.000-g sample of a certain isotope to decay to 0.350 g. What is the half-life of this isotope
A sample of gold weighs 1.2 oz. The sample is pounded into a thin rectangular sheet with an area of 400. sq. ft. The density of gold is 19.3 grams per cm3. What is the thickness of the foil in centimeters
Calculate the mass percent of carbon in the compound and calculate What is its final temperature
A 6.11 g sample of Cu---Zn alloy reacts with excess aqueous HCl producing 1.26 L of H2(g) at 22.0 degrees C and 728 torr. Since only the Zn portion of the alloy reacts, calculate the percent Cu in the alloy.
The reaction 2NO2 -> 2NO + O2 has the rate constant k= 0.65 M-1s-1. If the initial of NO2 is 7.30 x 10-2 M, how would you determine how long it would take for the concentration to decrease to 1.70 x 10-2M
Devise a chemical method for distinguishing between maleic and malonic acid. I thought of bromination of maleic since it is an alkene. Would bromination also occure with malonic acid
What is the molarity of 175 mL of a solution containing 2.18 g of Na2SO4·10H2O? 0.00377 M B. 0.644 M C. 0.00878 M D. 0.00118 M E. 0.0387 M
1. draw a six-carbon-chain portion from isotactic polypropylene in which all of the groups point in the same direction
Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of BrO3- is tripled and that of Br- is tripled? Just put in the number as a whole number or fraction.
A 500 mL buffer solution containing 0.2M fomic acid and 0.25 sodium formate is mixed with 100ml of 0.05M HCl. What will be the pH of this new solution
