In writing an equation that produces hydrogen gas the correct representation of hydrogen gas is

Sources of nitrogen for fertilisers included saltpetre from Chile, and guano. Guano is the droppings of seabirds, bats and also seals. They determined what the best conditions were in order to get a high yield of ammonia, and found these to be high temperature and high pressure. During World War I, the ammonia produced by the Haber process was used to make explosives.

Hydrogen is usually produced by the steam reforming of methane gas (natural gas). At high temperatures (–), steam () reacts with methane () in an endothermic reaction to yield syngas, a mixture of carbon monoxide () and hydrogen (). Daniel A. Crowl/Joseph F.

The equation AX → A + X is the general equation for a: In writing an equation that produces hydrogen gas, the correct representation of hydrogen gas is: H2 #2: In the equation 2KClO3 → 2KCl + 3O2, how many: mol #3.

You must know what the reactants are, and what the molecular formula of each one is. You must also know what the products of the reaction are, and how to write the molecular formulas for the products.

Then you can go about writing the equation for the reaction and balancing the reaction.

Oxygen - Wikipedia

In a chemical reaction, elements combine into compounds, compounds decompose back into elements, or transform existing compounds into new compounds.

Because atoms are indestructible in chemical reactions, the same number of atoms of element must be present before and after any reaction. This is based on the principle of conservation of mass. To balance a chemical equation, you must use stepwise reasoning. Sometimes there is some trial and error involved until you get enough practice to be good at it.

It is something best learned with a lot of practice! The bottom line in any balanced reaction, and the way to test if you've done it correctly is this: Let's use this example: The unbalanced reaction is this: Notice that the way the reaction is written not, 4 hydrogen atoms H go in, but only 2 come out in the H2O and also 3 oxygen atoms O go in as reactants, only 2 come out as products.

This is NOT balanced! The nitrogen Nby chance, does happen to be balanced: To balance the reaction, we will add coefficients, or numbers, in front of certain reactants and products to make sure what goes in comes out!

First, assign 1 as the coefficient of one species or compound or elementand usually you want to chose the most complicated compound containing the most elements. Here we should pick NH4NO3.

Secondly, find the elements that appear in only one other place in the equation, and assign coefficients to balance the numbers of their atoms. In our example, N appears in only one other place N2Oand a coefficient of 1 for N2O ensures that for the 2 N's that go in, 2 come out.

Hydrogen appears in H2O, and so its coefficient is 2 to balance the 4 H atoms on the left side.

So now we have: In this case it is, as there are 3 on the left side and 3 on the right side. The number one is implied if you don't write a number. In the same way, there are 10 H's in butane, and they can only go into the water, and so the coefficient in front of H2O must be 5 10 H's divided by 2 H's per water.

So now we have to make sure that 13 oxygen atoms are also on the left. Since we have O2 as the reactant, we can use a fraction as a coefficient to make the numbers come out right.

Since we want 13 total, what number times 2 equals 13? However, often people prefer to eliminate fractions because it makes it a bit easier to look at and work with.

To do that, we simply multiply everything on both side of the arrow by 2: Sometimes you can balance a reaction by just looking at it and figuring it out very easily it's called doing it "by inspection".

Other times it can be trickier and these steps can help. Assign the number 1 as the coefficient to one species.Natural petroleum gases contain varying amounts of different (primarily alkane) hydrocarbon compounds and one or more inorganic compounds, such as hydrogen sulfide, carbon dioxide, nitrogen (N 2), and pfmlures.comterizing, measuring, and correlating the physical properties of natural gases must take into account this variety .
