You put your hand on a hot stove and feel that it is hot. You quickly pull your hand away and see that it is slightly burned. What system is responsible for telling you to pull your hand away? What systems made it possible for you to pull your hand away? What system was damaged by the burn?

BRAINLIEST BEST OUTTA 2 AND 28pts

(SCIENCE NOT CHEMISTRY)

The nervous system, and the motor system

Explanation:

your nervous system sends the signal from your brain to your hand to pull your hand away. Then your motor system makes you pull your hand away. the system that is damaged is the nervous system because without it you wouldn't be able to feel anything and when you burned your hand some of the sensor like things that contect to your nervous system are damaged.

hope this helped :)

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
