Can a magnetic field sensor be made using semiconductor
material? If you say it can be done, draw the necessary schemes and
explain the theoretical calculations. Discuss which devices or
instruments will you use to determine physical quantities (indicate
which quantities are you going to find), and how you can determine
the magnetic field strength.
1. Methanol (CH4O) can be made by a reaction
between carbon monoxide gas and hydrogen gas. Methanol is the only
product of the reaction.
a) Starting with 75.0 g of each reactant, calculate the
theoretical yield of methanol.
b) How many grams of the excess reactant remains when
the reaction is over?
2. Silver(I) chloride is insoluble in water. A chemist
wishes to prepare 28.7 g of silver(I) chloride by mixing together
aqueous solutions of 0.400 M silver(I) nitrate and...
Methanol, CH3OH, can be made from the reaction of
carbon monoxide and hydrogen.
CO(g) + 2 H2(g) →
CH3OH(l)
What mass of hydrogen is required to produce 3.50 L of methanol
(d = 0.791 g/mL) if this reaction has a 73.01% yield under
certain conditions?
