Answers by Stanton D.

Heaven, Zygomycetes are a certain family of fungi. Like many other organisms, within the family there are species with all sorts of numbers of chromosomes! You'd have to go in and look up "ploidy" for a few species specifically, to get an idea of what's typical. I suspect, the purpose...

Courtney, There are just three types of systems of equations: 1) inconsistent = no solutions : such as (for two equations in two variables) two parallel but not overlapping lines 2) dependent = infinite number of solutions : such as (for two equations in two variables) two lines that...

I'd have to differ on the answer here. Richard P., the adiabatic lapse rate arises from a volume of gas expanding against a gradually decreasing surround pressure. Thus, such a gas packet does work on the surroundings as it rises, and experiences a loss of sensible heat as a result. Here, in spite...

April, I'll point you in the right direction on this one, since it's your third question today (that's close to spamming!) In chemistry, you must be agile at converting among several units of measure for substances. The one that's convenient to measure directly in the lab is mass (frequently...

April, You're posting an awful lot of questions today. Big test review? Charles' Law indicates that the volume a gas takes up is proportional to the temperature ****in degrees Kelvin****. Therefore, calculate what your initial and final temperatures are in degrees K (add 273.15 to the...

No Xavier, this is not the problem you had to solve. For several reasons. First of all, as stated you're given the decrease (negative change) in value (not cost, he's not still buying it!). Then, usually you'll have to solve a typical expression for value vs. time. But it's not a quadratic, it's...

Megan, Not so hard! First, call f(x) something more convenient, such as "y". That gives you: y=(x/2)-4 This takes you from an independent variable (x) to a dependent one (y). Note the standardized form of this equation: y is alone on one side, and x is manipulated on the other...

By and large, the average warming is most pronounced around the geographical polar regions, and almost negligible at the equator. However (a big however!), the size of the average temperature changes doesn't tell you directly everything; a 0.1oC increase at the equator will put far more water...

This question tries to trick you, perhaps, with the order of the instructions. You don't need to balance the equation in order to calculate the first answer (moles of Al): just divide 18.4g by the atomic weight of the element Al (on your periodic table). THEN you do need to balance the equation,...

Dear Xochitl, This is a typical heat transfer problem. The metal cools down from its initial temperature to the final temperature; the water heats up from its initial temperature to the final temperature. For each of these temperature changes in a material, the heat gain is Q = mass * temperature_change...

Man, Wyzant isn't for doing all your problem sets! I'll help you with the first question, a little. Both enthalpy and entropy are expressible either in terms of amount per unit, or amount in total. When you look up values for either property, they are listed in terms of amount per mole of...

Destiny, You should check your questions postings, this one seems to have lost most of itself. There's no figure, no given side or sides, and no data identified as perimeter or area (the usual things in such problems). Please redescribe completely in words, perhaps?

Sorry, Michael J., $0.11 * 0.113 = 1.34 cents, not dollars.   Colsten, if you're trying to match the energy drawn with the heating delivered, you may want to read the appliance label (usually inside the door-close area). The actual klystron power (microwave) output is somewhat less...
