I would say A and C. The circulatory system moves blood and nutrients similar to the plant moving water and nutrients. The endocrine system is responsible for hormones, glands and other such functions.
I believe your answer is: What is the enthalpy of formation of magnesium oxide?
Hope this helps! :)
(1.1232 * 10⁵) (6.022 * 10¹⁷)
Now, multiply simple numbers together and exponentials, together:
= 1.1232 * 6.022 * 10⁵ * 10¹⁷
= 6.763 * 10²²
In short, Your Answer would be 6.763 * 10²²
Hope this helps!
D.
This happens because in warmer temperatures, the atoms are more active. This increases the pressure because each atom uses up more space as they become more active.
