Students in Earth science are learning about Earth’s interior layers. They are investigating changes that occur as depth beneath Earth’s surface increases. Which of the following questions can best be answered during this investigation?

Question 2 options:

Why do both the temperature and pressure increase as you move towards the core?

Why does temperature increase and pressure decrease as you move towards the core?

Why do both temperature and pressure stay the same as you move towards the core?

Why does the temperature and pressure decrease as you move towards the core?

Identify the missing numbers below to show the result of multiplying the numbers (1.6 × 10-19)(5.0 × 106) = c × 10d

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
