One chemical reaction is called the Haber process, a method for preparing ammonia by reacting nitrogen gas with hydrogen gas:
This equation shows you what happens in the reaction, but it doesn’t show you how much of each element you need to produce the ammonia. To find out how much of each element you need, you have to balance the equation — make sure that the number of atoms on the left side of the equation equals the number of atoms on the right.
You know the reactants and the product for this reaction, and you can’t change them. You can’t change the compounds, and you can’t change the subscripts, because that would change the compounds.
So the only thing you can do to balance the equation is add coefficients, whole numbers in front of the compounds or elements in the equation. Coefficients tell you how many atoms or molecules you have.
For example, if you write the following, it means you have two water molecules:
Each water molecule is composed of two hydrogen atoms and one oxygen atom. So with two water molecules (represented above), you have a total of 4 hydrogen atoms and 2 oxygen atoms.
You can balance equations by using a method called balancing by inspection. You take each atom in turn and balance it by adding appropriate coefficients to one side or the other.
With that in mind, take another look at the equation for preparing ammonia: HOPE THIS HELPS
Answer:
pour in hot water and It will disolve
Answer:
Carbon is a highly covalent element due to the presence of four valence electrons in its outermost shell. This helps it bond covalently with other elements in various ways.
Carbon is known to be the backbone for most compounds. The carbon backbone vary in length and in the mode of bonding such as having the ability to from straight, branched, rings, double or triple bond which contibutes to the diversity and complexity of organic molecules.
Answer:
group, 6 or 16
Explanation:
as the group's progress going from the left of the table to the right of the the table, the valance electrons increase. although group 14 is split up by a ladder stair steppy thingy. the ones on the top take electrons, and the ones below give electrons.
Answer:
<em>C</em> NaOHsln = 0.125 M
Explanation:
Molarity (M) [=] mol/L
∴ moles NaOH = (0.125 L)(0.15 mol/L) = 0.01875 mol
∴ Vsln = 150 mL = 0.150 L
New Molarity:
⇒ <em>C</em> NaOH = 0.01875 mol/0.150 L
⇒ <em>C</em> NaOH = 0.125 M
