The element most to the left and the farthest down
It's a highly basic substance.
Good luck! (:
Answer:
convection could be a pot on a stove, radiation could be the sun and heat waves, and conduction could be a cup with coffee.
Explanation:
Conduction occurs when two objects are in direct contact with each other.
Convection is the transfer of heat through liquids and gases. Convection occurs above a hot surface because hot air expands and rises and is replaced by cooler, denser air.
Radiate energy is given off by a hot object and directly absorbed by another cooler object. This cause the cooler object to get warmer. Radiation can occur even if no air is present.
Answer:
d. 8
Explanation:
Valence electrons of oxygen = 6
Valence electrons of hydrogen = 1
The total number of the valence electrons = 6 + 2(1) = 8
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete.
In the water molecule,
<u>Oxygen has 2 bond pairs and two lone pairs which means that the total electrons in the valence shell is 8.</u>
This thermochemical equation needs to be balanced. Hence, option B is correct.
<h3>What is a balanced chemical equation?</h3>
A balanced equation contains the same number of each type of atom on both the left and right sides of the reaction arrow.
The balanced thermochemical equation is:
→ 
Hence, option B is correct.
