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:

Write a chemical reaction and make sure it's balanced;Identify STP (standard temperature and pressure, that is, T = 273.15 K and p = 1.00 atm);Find moles of oxygen;From the stoichiometry of the equation, identify the number of moles of ammonia;Convert moles of ammonia into volume using the ideal gas law pV = nRT.

(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!

Explanation:

If a uranium atom undergoes both alpha and gamma decay, then it means that there will be formation of one helium particle which is also known as alpha particle and gamma decay is the radiation or release of energy.

Whereas in a radioactive reaction, Uranium-235 absorbs a neutron and splits into two new atoms. As a result, there is formation of 3 new neutrons and a large amount of binding energy.

This reaction is as follows.

Thus, we can conclude that if a uranium atom undergoes both alpha and gamma decay, then the following will happen.

The nucleus loses neutrons.The nucleus loses energy.
