Answer:
model 3
Explanation:
Boron with atomic number 5 will have 3 valence electrons
Q = mass water x specific heat water x delta T.
<span>714,000 = mass water x specific heat water x 30.
Substitute specific heat water and solve for mass water.</span>
Reversals are the rule, not the exception. Earth has settled in the last 20 million years into a pattern of a pole<span> reversal about every 200,000 to 300,000 years, although it has been more than twice that </span>long<span> since the last reversal.</span>
Yes because the heat is to hot and would melt the earth layers so it would go through
