A specific combination of bonded atoms which always react in the same way, regardless of the particular carbon skeleton is known as the functional group. These are specific groups of atoms or bonds within organic molecules that accounts for the characteristic chemical reactions of those molecules. Examples of functional groups are the Carbonyl group, alkyl Halides, aldehydes and ketones among others.
A resting heart rate is usually around 40 beats per minute (Thats the normal amount)
Answer:
The periodic table is a marvel of organization, with each column and each row showing all ... Scientists identified the rest of them in the first half of the 20th century. ... They created in their lab a synthetic, previously unknown element. ... The Berkeley scientists did this for weeks on end, and produced a tiny amount of curium.
Explanation:
Answer:
The "word equation" is Magnesium + Dioxygen → Magnesium Oxide
Explanation: This is also the same as Mg + O₂ → MgO.
Reaction 3 is different from the rest and it is because a single product is synthesized.
Option 2
<u>Explanation:</u>
The reaction given in 1,2 and 4 are dissociation reaction where a single compound is getting split into two compounds. So all those three reactions are exothermic as they are breaking the bonds leading to release of energy to the surrounding. But the reaction 3 is a formation reaction, where two chemical compounds are forming a single compound.
So in this case, new bonds are formed leading to absorption of energy from the surrounding. So this is an endothermic reaction. Thus, reaction 3 is different from the rest and it is because a single product is synthesized.
