Ammonia (NH3) clouds are present around some planets. Calculate the number of grams of ammonia produced by the reaction of 5.4 g
Komok [63]

Answer:

30.4 g. NH3

Explanation:

This problem tells us that the hydrogen (H2) is the limiting reactant, as there is "an excess of nitrogen." Using stoichiometry (the relationship between the various species of the equation), we can see that for every 3 moles of H2 consumed, 2 moles of NH3 are produced.

But before we can use that relationship to find the number of grams of ammonia produced, we need to convert the given grams of hydrogen into moles:

5.4 g x [1 mol H2/(1.008x2 g.)] = 2.67857 mol H2 (not using significant figures yet; want to be as accurate as possible)

Now, we can use the relationship between H2 and NH3.

2.67857 mol H2 x (2 mol NH3/3 mol H2) = 1.7857 mol NH3

Now, we have the number of moles of ammonia produced, but the answer asks us for grams. Use the molar mass of ammonia to convert.

1.7857 mol NH3 x 17.034 g. NH3/mol NH3 = 30.4 g. NH3 (used a default # of 3 sig figs)

In the diagram, what is happening to the ENERGY during Segment C? Phase Change Diagram_Water Question 16 options: The kinetic en
Leviafan [203]

There was an increase in kinetic energy during the segment C and in other segments

Recall: That temperature is a measure of the average kinetic energy, so increasing temperature all cause increasing kinetic energy and vice versa.

However too, the heat energy which is added during the phase change is usually used to overcome forces in order to hold the molecules together.

<h3>What is kinetic energy?</h3>

Kinetic energy is the type of energy an object or a body posesss due to it motion

The body usually maintains it's kinetic energy unless the speed changes

<h3>What it potential energy?</h3>

Potential energy is a type of energy an object or a body had due to its relative position.

COMPOUNDS

Elements are made up of one kind of atoms.

Compounds are made up of two or more kinds of atoms.

Elements cannot be broken down into simpler substances by any physical or chemical method.

Compounds can be broken down into simpler substances by chemical methods.

Elements have their own set of properties.

Properties of a compound differ from those of their elements.

Examples: Hydrogen, Oxygen

Examples: Water, Sodium chloride
