To find<span> the </span>valence electrons in an atom<span>, identify what group the element is in. An element in group 1A has 1 </span>valence electron<span>. For example, Li is in group 1A, so that means it has one </span>valence electron. If the element is in group 2A, then it has two valence electrons<span>.</span>
<span>The chemical reaction of a reversible reaction is actually
governed by Le Chatelier’s principle. It states that when more reactants are
introduced into the system, the reaction will proceed forward to create more
products. So since Hydrogen is a reactant and Nitrogen is also reactant so
adding more Hydrogen makes more products hence reducing the Nitrogen
concentration.</span>
Answer:
d and e
Explanation:
We have 5 solutions with different molar concentrations, that is, the quotient between the number of moles of solute and the liters of solution. This can be expressed as mol/L or M. The most dilute would be the one having the less number of moles of solute per liters of solution, that is, solution d or e, which have the same concentration. If we order them from the most diluted to the most concentrated, we get:
d = e < a < b < c
Answer:
No
Explanation:
It is not correct to say that an object with the largest volume has the largest mass.
Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.
Mass is the amount of matter in a substance. Volume is the space a body occupies.
- A balloon and a stone for example is a typical one.
- A balloon has more volume but far lesser mass compared to a stone.
- A stone, gravel sized has low volume but more massive than a balloon.
Therefore, it is wrong to say a balloon has more mass because it has more volume.
