Here is the full question:
Cu(s) + 4HNO3(aq) -> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
1.000 g copper wire is reacted with 10 mL of concentrated nitric acid (16M). If 0.953 g of copper was actually recovered at the end of the entire experiment, what would be the percent yield?
Answer:
95.30 %
Explanation:
equation for the reaction is given as:
Cu(s) + 4HNO3(aq) -> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
1.00 g of Cu = 
= 0.01574 mol of Cu
10 mL of 16 M HNO3 = 
= 0.16 mol of HNO3
However, from both variables; we can arrive at a conclusion that Cu is the limiting reagent.
therefore % yield = = 4.70 %
Percentage yield = 
Percentage yield = 
%
Percentage yield = 0.953 × 100%
Percentage yield = 95.30 %

<span>The
immediate destructive action of a nuclear explosion is caused by shock. The answer
is letter D. The shock wave cause an instantaneous jump in pressure at the
schock front. The combination of the pressure produced in the front and the
jump causes the damage.</span>
ANDESITE is a fine grained rock that formed when magma irrupt it onto the surface and crystallized quickly ANDESITE & DIORITE have a composition that is intermediate between basalt.This is because their parent magmas formed from the PARTIAL melting of a BASALTIC oceanic plate.
Answer:
20 pretzels.
Explanation:
So in the first bag there at 64 pretzels in 16-ounces.
We can divide both these numbers by 16, to get 4 pretzels per ounce.
If we multiply both numbers by 5, we get 20 pretzels per ounces.
So, 20 pretzels i5-ounce bag.
