Answer:
C: metals donate electrons to non metals
Explanation:
When a high amount of heat is supplied, the sugar melts faster than when a low amount of heat is supplied.
<h3>What is melting?</h3>
The term melting has to do with the breakdown of the bonds that hold the molecules of a substance together. Melting occurs when heat is applied continously to a body.
Now, the time taken for the sugar to melt depends on the amount of heat supplied. In other words, when a high amount of heat is supplied, the sugar melts faster than when a low amount of heat is supplied.

Answer:
0.1832 moles of ethyl acetate ()
Explanation:
1. Find the balanced chemical equation:
In the production of ethyl acetate, the acetic acid reacts with ethanol to produce ethyl acetate and water, that is:
2. Find the theoretical maximum moles of ethyl acetate :
As the problem says that the acetic acid is the limiting reagent, use stoichiometry to find the moles of ethyl acetate produced:
The valence electron does the halogens possess are 7
- Valence electrons are found in the outermost energy level of an atom
- They are involved in the formation of chemical bonding with other atoms.
- The halogens elements are found in group 17 on the periodic table
- The halogens include fluorine, chlorine, bromine, iodine and astatine.
- They have seven valence electrons, so they are extremely reactive as they only need one more to fill their outer shell.
- By octet rule we can say that the electron with 8 outer most shell is full and stable.
Hence the halogens posses 7 valence electron
