What is the reducing agent?
What happens to the interference pattern that results from the diffraction of electrons passing through two closely spaced slits if the rate of electrons going through the slits is decreased to one electron per hour
The rate constant of a reaction is 7.50*10-5 L/mol·s at 195°C and 5.30*10-3 L/mol·s at 258°C. What is the activation energy of the reaction, in kJ/mol
Calculate the energy of the frequency at which they are broadcasting. (In kilojoules)

Choose the element with more negative (more exothermic) electron affinity from each of the following pairs.
What mass of natural gas (CH4) must burn to emit 470. kJ of heat? CH4(g) + 2 O2(g) CO2(g) + 2 H2O(g).
The biggest problem I'm running into is how to complete the ICE chart for the columns Change and Revised Equilibrium. I don't know where those numbers come from.
given that hclo4 an aqueous solution is 4.810-8 m write the equation for the reaction of hclo4 compute h3o oh- poh and
H2S and H2O have similar structures and their cenertal atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why this is.
What is the phenomenon that occurs when excited gaseous elements emit only a few colored lines? a. Planck's constant
