https://www.youtube.com/watch?v=Gi-ItrJISQE
You have just finished watching "A is for Atom" a film about nuclear energy made in 1953. Based on the presentation of the information,
a) How confortable do you think people were with the use of nuclear power in 1953?
b) How comfortable are you with the use of nuclear power today?
For a building with a greenroof that is 760x650 feet, determine the weight of water ( in lbs) that would be on the roof when the greenroof is saturated. Liquid water is 62.4 pounds/cu-foot
Calculate the number of chromium atoms in a 2.0 cm by 1.0 cm by 7.0 cm piece of this stainless steel. Calculate the number of 52Cr atoms in the above sample. The natural abundance of 52Cr is 83.789%.
Calculate the molarity and standard deviation of MnSO4 stock solution using the molarity
The density of copper metal is 8.95g/cm3. Explain if the radius of a copper atom is 127.8 pm, is the copper unit cell simple cubic, body centered cubic, or face centered cubic
At a given temperature, the equilibrium constant K for the reaction 2SO2(g) + O2(g) 2SO3(g) is 3.0 × 109. If 2.80 mol of SO2 and 4.06 mol of O2 are placed in a 1.78-L container.
Before the reaction began, the concentrations of the reactants were 0.060 M of SO2 and 0.050 M O2. After the equilibrium is reached, the concentration
