State an opposing argument. This is usually an argument that people opposed to your idea frequently use and that is probably known to your audience.What would people who don’t agree with you say to your argument? Next, reduce the impact of these arguments by exposing their weaknesses. State your reaction to the opposing argument.Be sure to show respect for other points of view. Reasonable people are sometimes deceived or misunderstand.But also strongly state your reasons for not accepting that opposing argument. Support your response with reasoning and evidence. It is very important to have strong supporting material from credible sources to back up your point of view in your refutation.Use a credible source to counter the argument. Indicate what effect, if any, opposing arguments have had on the strength of your case. For example, you might say that there may be some drawbacks to your proposal, but the benefits outweigh the costs.Or you might argue that the opposition has many more disadvantages and drawbacks.

The aurora is caused when electrons and protons, moving in the earth's magnetic field of $5.0 \times 10^{-5}$ T, collide with molecules of the atmosphere and cause them to glow. Part A What is the radius of the circular orbit for an electron with speed $5.0 \times 10^6$ m/s? Assume that the electron moves in a plane perpendicular to the magnetic field. Express your answer with the appropriate units. Part B What is the radius of the circular orbit for a proton with speed $6.0 \times 10^4$ m/s?

KINETICS AND EQUILIBRIUM Using an integrated rate law for a first-order reaction Consider this reaction: $2H_3PO_4(aq)\rightarrow P_2O_5(aq) + 3H_2O(aq)$ At a certain temperature it obeys this rate law. $\text{rate} = (0.00683 \text{ s}^{-1})[H_3PO_4]$ Suppose a vessel contains $H_3PO_4$ at a concentration of 0.990 M. Calculate the concentration of $H_3PO_4$ in the vessel 88.0 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits.
