Answer:
It's heat energy
Explanation:
which is transmitted through radiation. The sun warms us.
Answer:
Potential energy is the stored energy of position possessed by an object.
<span>Answer:
3 electron pairs
Let's take BF3 for an example.
When you find the valence electrons for this molecule --> [3+(3x6)], you'll get 24e-. You draw the Lewis dot structure and each of the F atom would have six dots around it (a total of 18 because there's 3 F atoms) and the B would have three lines [one line attached to each F. One line would equal to 2 valence electrons] and you get a total of 24 valence e-.
The question asks how many groups are on the CENTRAL atom, meaning on the B. It would be three</span>
Answer: Temperature increase
Explanation:
Endothermic reaction means the absorb of heat from the surrounding. So when heat is absorbed from the surrounding then the temperature of the reaction will increase
The double or triple bond are needed because as they serves as a source of electron density and serves as a nucleophile.
The double bond or triple bond are electron rich entities capable of donating electrons thus act as nucleophile (species that donate electrons) and serve as electron dense region in molecules.
