Answer:
option C = Reactant: 4NH₃ + 6NO → product: 5N₂ + 6H₂O
Explanation:
Chemical equation:
NH₃ + NO → N₂ + H₂O
Balanced chemical equation:
4NH₃ + 6NO → 5N₂ + 6H₂O
Ammonia is react with nitrogen mono oxide and produced nitrogen and water.
Ammonia and nitrogen monoxide are reactants while water and nitrogen are product.
Four number of moles of ammonia react with six nitrogen monoxide and produced five mole of nitrogen and six mole of water.
Answer:
CO2(g)
Because CO2 is the larges molecule with specific geometric, therefore it is not likely to behave as an ideal gas.
Answer: 100kPa
Explanation:
P1 = 3.00 x 10² kPa , P2 =?
T1 = 30°C = 30 +273 = 303k
T2 = —172°C = —172 + 273 = 101k
P1/T1 = P2/T2
3 x 10² / 303 = P2 / 101
P2 = (3 x 10² / 303) x 101
P2 = 100kPa
Half life of a radio-active material is refereed to the time required for reducing its activity to 50 %.
Now, when I-131 passes 1st half life, it's activity will reduce to half i.e. 50%
When, I-131 passes 2nd half life, activity of I-131 will be reduced to 25%
On passing, 3rd half-life, percent activity of the I-131 <span>remaining will be 12.5 %.</span>
Explanation:
All boron isotopes have 5 protons.
B11 has 6 neutrons, so its atomic mass is:
6 (1.008664 u) + 5 (1.007276 u) = 11.0884 u
B10 has 5 neutrons, so its atomic mass is:
5 (1.008664 u) + 5 (1.007276 u) = 10.0797 u
So the average atomic mass of boron is:
0.80 (11.0884 u) + 0.20 (10.0797 u) = 10.8866 u
The closest whole number is 11.
