Consider a metal atom, which we will give the symbol M. Metal M can readily form the M+cation. If the sphere on the left below represents the metal atom M, which of the other three spheres would probably represent the M+ cation? Explain your choice.
Given the hypothetical redox reactions involving substances A, B, and C: A + B+ g? A+ + B C + A+ g? C+ + A B + C+ g? no reaction What is the arrangement of the substances in their order from strongest reducing agent to weakest reducing agent
Consider the following balanced equation: 2 N2O5 → 4 NO2 + O2. If a 5.00 g sample of N2O5 undergoes this reaction, how many grams of O2 will also be formed?
If you have a beaker of gas and all of the gas in that beaker is moved to a container half the size, the temp is maintained, what would the gas look like
One mole of CO29(g) is mixed with one mole of H2 (g) and passed over a catalyst for the following reaction: CO(g)+2H2(g)=CH3OH(g) At 500 K and a total pressure of 100 bar, 0.40 mol of CH3OH is gounf at equilibrium. What are the values of Kp and Kc?
