348 g of water starting at 10.0°C is heated until its temperature is 87°C. Calculate the amount of heat energy needed to cause this rise in temperature. Specific heat of water is 4.184 J/g°C

- 112,114.46 J
- 32,178.64 J
- 75,369.81 J
- 95,644.29 J

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
