The reactivity of metals on the periodic table

Chemistry
1 answer:
kari74 [83]3 years ago
8 0

Explanation:

The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting.

If 3.95 g of N2H4 reacts and produces 0.750 L of N2, at 295 K and 1.00 atm, what is the percent yield of the reaction?
adell [148]
Molar mass of N2H4 = 32 grams/mole 
<span>3.95 grams of  N2H4 = 3.95/32
                                  = 0.123 moles </span>

<span>This will produce 0.123 moles of N2 </span>
<span>Now,
From the gas law equation. </span>
<span>P.V = n x R x T </span>
<span>P = 1 atm (given)
V = </span><span>0.123</span><span> x 0.082057 x 295 </span>
<span>V = 2.97 Liters </span>

<span>Theoretical yield = 2.97 Liters.
Actual yield = 0.750 Liters </span>

percentage yield = (0.75/2.97) x 100 %
                           = 25.25 %
