It is estimated that a brachiosaurus weighed around 124, 000 pounds. a tyrannosaurus rex weighed about 8.16*10^3 kilograms. of a tyrannosaur eats an entire brachiosaurus, about how much will the tyrannosaur weigh? use scientific notation and give your answer in grams.

  6.44×10⁷ g

Step-by-step explanation:

The scenario seems unlikely, as a brachiosaurus weighs about 6.9 times as much as a tyrannosaur. The sum of the two weights is ...

  8.16×10³ kg + 1.24×10⁵ lb

  = 8.16×10³ kg + (1.24×10⁵ lb)/(2.2046 lb/kg)

  = 8.16×10³ kg + 5.62×10⁴ kg

  = 6.44×10⁴ kg . . . . . rounded to 3 significant figures

  = 6.44×10⁷ g . . . . . . weight of not-so-hungry tyrannosaur

1 kg = 10³ g

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
