Tin(II)nitride :
Formula Sn₃N₂<span>.
</span>
Percent yield is calculated by obtaining the ratio of the actual yield and the theoretical yield times 100.
Actual yield = 1500 kg
Theoretical yield = 1500 ( 1 / 30.00 ) ( 2 / 2 ) ( 46.006 / 1 ) = 2300.3 kg
Percent yield = 1500 / <span>2300.3</span> x 100 =<span> 65.21 %
Therefore, the correct answer is the last option. Hope this answers the question.</span>
First convert to moles:
0.5113 g / 17 g/mol = 0.0301 mol
Now create a ratio based on the reaction provided to solve for the unknown:
4 NH3 / -905.4 kJ = 0.0301 mol NH3 / x kJ
x = -6.808 kJ
Answer:
Rubber, or another insulator.
Explanation:
I'm not sure what the options are, but Sue would probably want an insulator so that the heat is trapped, keeping her hands cool.
