Biography

I am certified chemistry teacher in the state of Connecticut. I have been teaching for more than 25 years at the high school level. I enjoy working with my students to solve problems and seeing them succeed. I love the outdoors and especially camping and hiking with my wife and two sons. I also enjoy gardening, growing my own vegetables, practicing martial arts, and making pizza with my family.

Which statement best describes how the kinetic molecular view of gases can be used to explain the effect of gas temperature on gas pressure?
As temperature increases, the particles are damaged, slowing them down and decreasing the number of collisions against the beaker; therefore the pressure decreases.
The effect of temperature on pressure depends upon the gas.
Gas pressure and gas temperature are unrelated.
As temperature increases, the particles are split apart so that there are more collisions against the beaker and the pressure increases.
As temperature increases, the speed of particles increases, so there are more collisions against the beaker and the pressure increases.

Decide whether these proposed Lewis structures are reasonable. Proposed Lewis structure Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "O,O".
