Well, we need to find the ratio of Al to the other reactant.
Al:HCl = 1:3
--> this means that for every 1 Al used, you have to use 3 HCl.
6*3 = 18 moles of HCl needed to fully react with 6 moles of Al. Since 13<18, HCL is the limiting reactant.
The ratio of HCl:AlCl = 3:1
13/3 = 4.3333...
The final answer is HCl is the limiting reactant with 4.3 moles of AlCl3 able to be produced.
Hope this helps!!! :)
Answer:
The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element

Answer: Hydrogen ion concentration of the lake is 
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.
To calculate the pH of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
pH = 4.0
Putting values in above equation, we get:
![4.0=-\log[H^+]](https://tex.z-dn.net/?f=4.0%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=10^{-4.0}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-4.0%7D)
![[H^+]=10^{-4}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-4%7D)
Thus hydrogen ion concentration of the lake is
1. Pressure decreases with increasing volume as the increased volume increases space for molecules to move around, thus decreasing the collisions and decreasing pressure.
2. A has a higher pressure given that the higher the n value, or moles present, the higher the pressure will be if everything else is held constant.
3. Gases have weaker intermolecular forces than liquids and solids.
4. Pressure must be 1/2, or 0.5 as PV=k, (P)(4)=(2), (P)=(2/4)
5. 2.25 L
6. Increasing space will decrease collisions and vice versa
7. 1122 2L bottles
8. 2.35 L
9. 2.1428 L
10. It would expand as they are directly proportional
11. 2.14959 L
12. 546K
13. .003663 atm`K
14. If pressure and temperature are directly proportional, then they increase or decrease at a constant rate
15. quadruples as they are directly proportional
16. 18.9963587 atm
Sorry hun, I gotta go. Good luck!
