How many liters of nh3, at stp, will react with 19.5 g o2 to form no and h2o?

10.9 L

Explanation:

Let's begin by introducing the strategy to solve this problem:

(a) The first step is already fulfilled: the reaction is balanced and it shows that 4 moles of ammonia react with 5 moles of oxygen.

(b) Given the following variables:

(c) Find moles of oxygen dividing mass of oxygen by its molar mass:

Here molar mass of oxygen is:

(d) From stoichiometry, dividing moles of ammonia by its stoichiometric coefficient would be equal to the ratio of moles of oxygen divided by its stoichiometric coefficient:

Rearrange the equation to obtain moles of ammonia:

(e) Solve pV = nRT for volume of ammonia:

Substitute the given data to obtain the final answer!

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
