Answer:
mass of excessive CO = 2.55 gram
Explanation:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
moles of Fe2O3 = mass / formula mass = 22.00/(56x2+16x3)=0.1375 (mol)
moles of CO = mass / formula mass = 14.1/(16+12) = 0.503
Fe2O3 reacts completely meanwhile CO is excessive.
mass of CO reacts = 3 x nFe2O3 x M = 3 x 0.1375 x (16+12) = 11.55 gram
mass of excessive CO = initial mass - reacted mass = 14.1 - 11.55 = 2.55 gram

The cathode serves as the positive terminal and the anode as the negative terminal. The flow of electrons is from the cathode to the anode.</span><span>The relationship between a cathode and an anode involves electrons. An example of this is reaction that takes place in an electrolytic cell. It has a cathode compartment, an anode compartment and a salt bridge that divides the compartment. The movement of electrons is from the cathode to the anode. </span>
Answer:
the quantity of solution to moles for d is significantly lower.
Explanation:
the larger the amount of liquid, the less amount of ions to dissociate hence having a lesser amount of chloride ions.
compared to b which is less liquid and a higher concentration
<u><em>Buffers</em></u> <span>are solutions that resist changes in ph when moderate amounts of acids or bases are added and contain ions or molecules that react with oh- or h when these ions are introduced into solution.</span>
Answer:
<h2>9 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 3 × 3
We have the final answer as
<h3>9 kg.m/s</h3>
