Answer:
The reason why Newtons first law of motion is sometimes called the law of inertia is because it states that if the object is in motion, it will not rest unless an unbalanced force acts on the object.
Answer:
Russia es el mejor pais? Vladimir Putin, es el mejor presidente del mundo
The value of ΔS° for reaction is - 22.2 J/K.mol
→ 
Calculation,
Given value of S°(J/K.mol) for
= 248.5
= 240.5
= 210.6
= 256.2
Formula used:
ΔS° (Reaction) = ∑S°(Product) - ∑S°(Reactant)
ΔS° = (256.2 + 210.6 ) - ( 248.5 + 240.5) = 466.8 - 489 = - 22.2 J/K.mol
The change in stander entropy of reaction is - 22.2 J/K.mol. The negative sign indicates the that entropy of reaction is decreases when reactant converted into product.

If you have a concern about fluoride in your drinking water, you can get more information by contacting the local community water system and is denoted as option D.
<h3>What is Water?</h3>
This is referred to as a universal solvent and is usually colorless and used for various purposes such as drinking, washing etc.
Fluoride is added to water by the the community water system as it helkps to build strong teeth and cavities thereby preventing tooth decay. They know the concentration which is added to the water which is why they need to be contacted for more information.

Explanation:
Alkali metal cations reacts vigorously with halogens to form ionic/electrovalent compounds.
- The alkali metals are about the most reactive metals and they belong to group I .
- In their outermost shell, they have one valence shell electron.
- Alkali metals are largely electropositive willing to release their valence electron to attain stability.
- The halogens have seven electrons in their outermost shell. To complete their configuration, they need just one electron.
- All the halogens are strongly electronegative and they are readily reactive.
- In the vicinity of group 1 elements, they react vigorously.
- This is due to the electrostatic attraction between the metal and non-metal ion formed.
- Therefore, they form strong ionic bonds between their compounds.
