Either Fossil Fuel or Compost.. I would go with Fossil Fuel.
Answer:
The correct answer is D
Explanation:
Many substances hold their molecules together in the liquid or solid bosom. This is due, in addition to the pressure and temperature conditions, by the forces of Van der Waals. These are still produced in nonpolar molecules by the movement of electrons through the molecules; in extremely short periods of time, their electrons "charge" towards one end of the molecule, producing small dipoles and keeping the molecules very close to each other.
Mass of ammonia produced : 121.38 g
<h3>Further explanation</h3>
Given
Reaction
3H₂(g) + N₂(g) ⇒ 2NH₃(g)
100g of N₂
Required
Ammonia produced
Solution
mol of N₂ :
From the equation, mol ratio of N₂ and NH₃ = 1 : 2, so mol NH₃ :
mass of NH₃(MW=17 g/mol) :
First you need to know how ionic compounds are created!
Ionic compounds are formed by IONS (Obviously, what am I, a dummy?)
There are two types of ions: anions and cations.
Anions can only be formed by nonmetals, and cations can only be formed by metals.
In order for ions to bond, there must be one anion and one cation, because opposite charges attract.
Let's look at your choices.
1) Ca + Br can form ionic bonds
2) Na + F can form ionic bonds
3) Li + Cl can form ionic bonds
However...
4) Mg + Ar
This is a special case. Ar is a NOBLE GAS, which means that it has the maximum number of valence electrons (8) in its outermost shell. Therefore, ANY type of bonding is IMPOSSIBLE.
Your answer should be 4) Mg + Ar
Answer:
ionic bonding
Explanation:
In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
