What observations might enable us to deduce that a chemical change has occured when dilute aqueous solutions are mixed?
Explain why trans-1,2-difluoroethane is a non-polar molecule that while cis-1,2-difluoroethane is a polar molecule. Acrylonittrile has the formula CH2=CH-CN. Draw a line bond formla for acrylonitrile and label sigma bonds, pi bonds, which carbon at..
A buffer is made with 25mL of 1.0 M HC2H3O2 and 25mL of 1.0 M NaC2H3O2. Calculate the theoretical pH. I know the pH is 4.74.
A 21.496 g sample of magnesium is burned in air to form magnesium oxide and magnesium nitride. when the products are treated with water, 2.813 g of gaseous ammonia are generated.
You want to prepare a solution that is 0.200m in Na2CO3. How many grams of the salt must you add to 125g of water? What is the mole fraction of Na2CO3 in the resulting solution?
Draw viable Lewis structures to illustrate how the element bromine can take part in an ionic bond, a pure covalent bond, and a polar covalent bond.
The Henry's law constant for helium gas in water at 30°C is 3.7 10-4 M/atm; that for N2 at 30°C is 6.0 10-4 M/atm. If the two gases are each present at 1.2 atm pressure, calculate the solubility of each gas. What is the Molarity of He and N2
