In 1897 the swedish explorer andreé tried to reach the north pole in a balloon. the balloon was filled with hydrogen gas. the hydrogen gas was prepared from iron splints and diluted sulfuric acid. the reaction is
fe(s)+ h2so_4(aq) > feso4(aq) + h2(g)
the volume of the balloon was 4800 m^3, and the loss of hydrogen gas during filling was estimated at 20.%. what mass of iron splints and 98% (by mass) h2so4 were needed to ensure the complete filling of the balloon? assume a temperature of 0^c, a pressure of 1.0 atm during filling, and 100% yield

Explanation:

Hello,

Based on the given data, the corresponding moles of hydrogen to fill the balloon without loss is:

Now, considering the 20% loss of hydrogen, the amount that ensured the complete filling was:

Based on that result, we proceed to computed the amounts of both iron and 98% by mass sulfuric acid that were needed to ensure the complete filling of the balloon as follows:

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

lol for the pointsss
