There are 2 Nitrogen atoms (or parts) of Nitrogen on the left side of the equation, and 2 Hydrogen, and only one Nitrogen but three Hydrogen on the other side. Where did the extra Nitrogen go? Where did that Hydrogen come from? The answer is Stoichiometry.
N2 + H2 --> NH3 has to be balanced, so we add coefficients to the reactants and products, which indicate in what ratio they are consumed in the reaction. They effectively multiply the subscripts on the elements.
To balance Nitrogen, we have to add a 2 to the front of NH3, so we get 2NH3. Nitrogen is balanced, but Hydrogen isn't. There are now 6 Hydrogen being produced by the reaction, so we can add a 3 to the products side, making 3H2.
Now we have N2 + 3H2 --> 2NH3, and everything is balanced.
The ratio is 2:6, or 1:3
Metamorphic rocks are not easy to make, they are made from rock being exposed to enormous amounts of heat and pressure. Examples of these rock<span> types include marble, slate, gneiss and schist. </span>

Hey there!
Great question;)
Answer:it is neutrally charged because it has the same number of protons(positively charged iona) and electrons(negatively charged ions)
I hope this helps:)
Answer:
there are 20 different types of aminoacyl trna synthetases
Explanation:
aminoacyl trna synthetases also called trna ligase, is an enzyme that attaches the appropriate amino acid onto its tRNA.
in humans, the 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases, one for each amino acids of the genetic code.
