Answer:
balanced equation mole ratio 5 2 mol NO/1 mol O2
10.00 g O2 3 1 mol O2/32.00 g O2 5 0.3125 mol O2
20.00 g NO 3 1 mol NO/30.01 g NO 5 0.6664 mol NO
actual mole ratio 5 0.6664 mol NO/0.3125 mol O2 5 2.132 mol NO/1.000 mol O2
Because the actual mole ratio of NO:O2 is larger than the balanced equation mole
ratio of NO:O2, there is an excess of NO; O2 is the limiting reactant.
Mass of NO used 5 0.3125 mol O2 3 2 mol NO/1 mol O2 5 0.6250 mol NO
0.6250 mol NO 3 30.01 g NO/1 mol NO 5 18.76 g NO
Mass of NO2 produced 5 0.6250 mol NO2 3 46.01 g NO2/1 mol NO2 5 28.76 g NO2
Excess NO 5 20.00 g NO 2 18.76 g NO 5 1.24 g N

okay lol, ima use this for points if okay
Explanation:
Answer:
This is because Corn is grown on land and has important values to man .These values include as a source of food for man and animals. It is also used as raw materials for the production of certain goods such as flour etc.
It is an energy resource because fermentation of corn gives rise to ethanol fuel which is used as a source of power to run machines and other equipment.
Answer:
Specific heat of copper = 0.385 J/(gi°C)
Explanation:
Given:
Mass of copper (m) = 200 g =
Initial temperature (T1) = 20°C
Final temperature (T2) = 40°C
Heat needed (Q) = 1,540 J
Find:
Specific heat of copper = ?
Computation:
⇒ Change in temperature (ΔT) = T2 - T1
⇒ Change in temperature (ΔT) = 40°C - 20°C
⇒ Change in temperature (ΔT) = 20°C
⇒ Specific heat of copper = Q / [mΔT]
⇒ Specific heat of copper = 1,540 / [(200)(20)]
Specific heat of copper = 0.385 J/(gi°C)
