Answer:
universal mass unit
<h2 />
The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
Answer:
5. 2 Al 3 Cl2 and 2 AlCl3
Cl2 is limiting
(It has the highest coefficients, but that's not always true. If they give you the number of grams for each make sure to work the math out)
6. C
(As the pressure increases there is less volume for the molecules to move around, therefore the molecules will be closer together, allowing for more collisions.)
7. b
(if the temperature is increases so will the rate of the reaction. The increase in temperature will allow for the molecules to move at a faster rate, allowing for more collisions (reactions) between them.
8. d
(dynamic equilibrium is the state at which the reaction is consistently moving, there fore the amounts should remain the same)
9. A
(a catalyst will lower the the pathway of activation energy because it's meant to speed up a reaction)
bro youre on your own after this, im tired
