Points \(M\) and \(N\) are the endpoints of the diameter of a circle with center at \(O,\) as shown below. Point \(P\) is on the circle, and \(\angle M O P\) measures \(60^{\circ}\) : The shortest distance along the circle from \(M\) to \(P\) is what percent of the distance along the circle from \(M\) to \(N ?\) A. 75\(\%\) B. 60\(\%\) C. 50\(\%\) D. 33\(\frac{1}{3} \%\) E. 16\(\frac{2}{3} \%\)
Traveling at approximately \(186,000\) miles per second, about how many miles does a beam of light travel in 2 hours? F. \(3.72 \times 10^{5}\) G. \(2.23 \times 10^{6}\) H. \(2.68 \times 10^{7}\) J. \(6.70 \times 10^{8}\) K. \(1.34 \times 10^{9}\)
From the results of Experiment \(2,\) what would one hypothesize, if anything, about the effect of the number of solute particles dissolved in \(\mathrm{H}_{2} \mathrm{O}\) on the boiling point of a solution? A. The more solute particles that are present, the higher the boiling point. B. The more solute particles that are present, the lower the boiling point. C. No hypothesis can be made because only 1 solute was tested. D. The number of solute particles produced does not affect the boiling point.
When nitrogen gas \(\left(\mathrm{N}_{2}\right)\) is reacted with \(\mathrm{H}_{2}\) under certain conditions, the following reaction occurs: $$\mathrm{N}_{2}+3 \mathrm{H}_{2} \rightarrow 2 \mathrm{NH}_{3}$$ Based on the results of Experiment \(1,\) if 10 \(\mathrm{mL}\) of \(\mathrm{N}_{2}\) were completely reacted with 40 \(\mathrm{mL}\) of \(\mathrm{H}_{2}\) at the same pressure and temperature, what volume of \(\mathrm{H}_{2}\) would remain unreacted? F. \(0 \mathrm{mL}\) G. 10 \(\mathrm{mL}\) H. 20 \(\mathrm{mL}\) J. 30 \(\mathrm{mL}\)
