Let's Create Direction: Read the situation below and write the correct sequence/steps on how your nerves, spinal cord and brain work together to react and respond to a hot object which you have accidentally touched. When a message comes into the brain from anywhere in the body, the brain tells the body how to react or respond to it. For example, you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your body. The brain then sends a message back telling the muscles in your hand to pull it away.

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.
