94.74 moles of NO₂ are produced.

Explanation:

Given data:

Volume of oxygen gas = 3714 L

Temperature = 273 K

Pressure = 1 atm

Moles of NO₂ produced = ?

Solution:

Chemical equation:

4NH₃  + 7O₂   →      4NO₂ + 6H₂O

Number of moles of oxygen:

At STP one mole of any gas occupy 22.4 L volume. Thus, 3714 L gas contain,

3714 L× 1  mol / 22.4 L

165.8 mol

now we will compare the moles of oxygen and nitrogen dioxide.

                    O₂         :        NO₂

                     7           :          4

                   165.8      :        4/7×165.8 = 94.74 mol

Thus, 94.74 moles of NO₂ are produced.

can you attach a picture of the lettuce? : )

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
