Use the passage below to answer the next two questions: Throughout Earth’s history, there have been cooling trends resulting in Ice Ages when glaciers covered most of the planet. When the temperatures decrease and sea ice begins to form, its white surface increases the albedo effect and solar radiation is reflected back into space causing temperature to decrease even more. This results in decreasing temperatures and the formation of more ice.

What type of feedback loop is occurring in this example?
Question 6 options:

Positive

Negative

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.
