If 12.5 grams of calcium is reacted with excess hydrogen chloride in a water solution according to the following chemical reaction, and the measured amount of 23.5
grams of calcium chloride is produced, what is the percent
yield for the reaction? Use
the balanced equation given below.
Ca (s) + 2HCl (aq) - CaCl2 (aq) + H2 (g)
First, calculate the theoretical yield, then calculate the percent yield. You must show
all your work with calculations with a proper set up including:
a. how you find the molar mass of CaCl2,
b. how you calculate the theoretical yield
C. how you calculate the correct percent yield.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

yes.. it's proven to be 36.

4. satellites sputnik, yeltsin, and plekov often temporarily line up in order in a great circle. the circumference of the earth is 24,900 miles, and the satellites orbit at about 150 miles above the surface. if, while in a great circle, sputnik is 9,000 miles from yeltsin, and yeltsin is 10,500 miles from plekov, how far apart are sputnik and plekov?

answer: b  

6,342 miles

5. identify the statement that is true in spherical geometry.

answer: d  

two distinct lines intersect in two points.
