Consider the following prediction. Prediction: If an increase in temperature increases the rate of evaporation of
water, then an increase in average daily temperatures will decrease lake water
levels over a two-year period.
Which of the following best describes this prediction?
A. The prediction is not useful because scientists are skeptical of
anyone who claims to see into the future.
O B. The prediction is useful because it proves that the hypothesis is
true before any data have been collected.
O C. The prediction is useful because it specifies what observations
will be made to test a hypothesis.
O D. The hypothesis is not useful because it is too long as a sentence
and therefore difficult to read.

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
