Explanation:
Calculate the number of grams of nitrogen dioxide that are produced from
4 moles of nitric oxide.
2NO(g) + O2(g) -->2NO2(g)
I really need help with this... I need to know how to work it too... I can balance it out but not sure about grams... This is it balanced out with 4 moles of nitric oxide
4NO(g) + 2O2(g) ->4NO2(g) please help and explain i want to learn this
Answer:
Since the noble gases are unreactive or inert, they are safe to use. Helium is used to fill balloons and airships, because it is much lighter that air and it will not catch fire. Neon is used in advertising signs. It will give red glow, but the color can be changes by mixing it with other gases.
Explanation:
I think you want to ask the complete ionic equation and net ionic equation. For complete ionic equation: 3Ba2+ + 6Cl- + 2Al3+ + 3SO42- -->3BaSO4 + 2Al3+ + 6Cl-. For net ionic equation: 3Ba2+ + 3SO42- -->3BaSO4.

Answer:</h3>
Final volume is 120 L

Explanation:</h3>
- Using the dilution concept, dilution involves adding more solvent to a concentrated solution to make it dilute. This results to a dilute solution with less solute concentration and more solvent.
According to the dilution equation;
M1V1 = M2V2
Where, M1 is the molarity and V1 is the volume of the concentrated solution, while M2 and V2 are the molarity and volume of the diluted solution respectively.
In this case;
M1 = 12.0 M
V1 = 30 L
M2 = 3.0 M
V2 = ?
Therefore;
V2 = M1V1 ÷ M2
= (12 × 30) ÷ 3
= 120 L
Hence, the final volume will be 120 liters
