For the reaction 2NH3(g) + O2(g) -> 2NO(g) + 3H2O(g). The reaction is run using 824 g NH3 and excess oxygen. How many moles of NO are formed? How many moles of H2O are formed?

Answers

Answer 1

Answer:

Explanation:

Step One

Find the molar Mass of NH3

N =   14

3H =  3

Mass = 17

Step Two

Find the number of moles of NH3

mols = given mass / Molar Mass

given mass = 824 grams

molar mass = 17

mols = 824/17

mols =  48.47

Step Three

Find the moles of NO

Here you have to look at the balanced equation

Every 2 mols of HN3 produces 2 mols of NO

So the number of mols of NH3 = 48.47

The number of mols of  NO      = 48.47

Step Four

Find the mols of H2O

2 mols of NH3 produces 3 moles of H20

48.47 mols H20 produces x moles of H20

3/x = 2/48.47     Cross Multiply

2x = 3*48.47

2x = 145.41         Divide by 2

x = 145.41/2

x = 72.71            mols of water.

wind is just high and low pressure of air, when a high pressure comes and crashes into a low pressure air pocket than it can form a wind storm.

Explanation:

The Uneven heating of the Earth's surface. Earth's rotation and unequal heating of the Earth's surface. air pressure towards regions of lower air pressure. ... air moving from areas of high pressure to areas of low pressure.

This is what will most likely cause a sudden wind to start blowing.

How do temperature, humidity, and pressure vary within an air mass?


A.Temperature and humidity vary, but pressure does not.


B.Humidity makes the pressure in an air mass increase.

There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples

Answers

Answer:

See explanation

Explanation:

While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.

Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.

Let us look at three examples;

The carbohydrate in food is composed of carbon, hydrogen and oxygen

The stainless steel materials we use are composed of iron, carbon and other trace elements

Glass is made up of silicon, oxygen and other elements

Only 90 naturally occurring elements capable of combining with each other to form millions of substances.

Compounds:

When two or more elements combine in a certain ratio to form a molecule.

For example-

Water is made up of two hydrogen and one Oxygen ration is 2:1.

If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.

Water gives life and Hydrogen peroxide can kill a person.

Other examples are,

The carbohydrate in food is composed of carbon, hydrogen and oxygen.  The stainless steel is made up of  iron, carbon and other trace elements.  Glass is composed of silicon, oxygen and other elements.

Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.
