What is a grain boundary. (Multiple answers can be selected.) 1. A point defect 2. A line defect 3. A two-dimensional interface where the solid structures are different
The atom then emits two photons: one of wavelength 1282.2 nm to reach an intermediate level and a second to return to the ground state. What was the wavelength of the second photon emitted?
caclculate the number of grams of Fe formed when 0.300kg of Fe2O3 reacts.
Use any other reagents that you need. Hint: you may first want to conduct some chemistry on each alkene first, then use the resulting products to make 1-decanol.
A buffer solution is prepared by adding 0.20 mole of NH3 and 0.30 mole of NH4Cl to enough H2O to make one liter of solution. K(a) = 5.7 x 10^-10 for NH4+
