Answer:
The rate is ![4,5 \times 10^{-5}\frac{mole}{Ls}](https://tex.z-dn.net/?f=%204%2C5%20%5Ctimes%2010%5E%7B-5%7D%5Cfrac%7Bmole%7D%7BLs%7D)
Explanation:
Stoichiometry
![CH_{3}Cl+NaOH \rightarrow CH_{3}OH+NaCl](https://tex.z-dn.net/?f=CH_%7B3%7DCl%2BNaOH%20%5Crightarrow%20CH_%7B3%7DOH%2BNaCl%20)
Kinetics
![-r_{A}=k \times [CH_{3}Cl] \times [NaOH]](https://tex.z-dn.net/?f=-r_%7BA%7D%3Dk%20%5Ctimes%20%5BCH_%7B3%7DCl%5D%20%5Ctimes%20%5BNaOH%5D%20)
The rate constant K can be calculated by replacing with the initial data
![1 \times 10^{-4}\frac{mole}{Ls}=k \times [0,2M] \times [1,0M] =5 \times 10^{-4}\frac{L}{mole s}](https://tex.z-dn.net/?f=%201%20%5Ctimes%2010%5E%7B-4%7D%5Cfrac%7Bmole%7D%7BLs%7D%3Dk%20%5Ctimes%20%5B0%2C2M%5D%20%5Ctimes%20%5B1%2C0M%5D%20%20%3D5%20%5Ctimes%2010%5E%7B-4%7D%5Cfrac%7BL%7D%7Bmole%20s%7D)
Taking as a base of calculus 1L, when half of the

(half is consumed)
(by stoicheometry)
![0,1 mole NaCl](https://tex.z-dn.net/?f=%200%2C1%20mole%20NaCl%20)
Then, the rate is
![-r_{A}=5 \times 10^{-4} \frac{L}{mole s}\times 0,1M \times 0,9 M=4,5 \times 10^{-5}\frac{mole}{Ls}](https://tex.z-dn.net/?f=-r_%7BA%7D%3D5%20%5Ctimes%2010%5E%7B-4%7D%20%5Cfrac%7BL%7D%7Bmole%20s%7D%5Ctimes%200%2C1M%20%5Ctimes%200%2C9%20M%3D4%2C5%20%5Ctimes%2010%5E%7B-5%7D%5Cfrac%7Bmole%7D%7BLs%7D)
The reaction rate decreases because there’s a smaller concentration of reactives.
Answer:
1) 4.0744 grams of aluminum chloride can be obtained.
2) 0.7652 grams of chlorine that react with 0.194 g of aluminum.
Explanation:
![2Al(s) + 3Cl_2(g)\rightarrow 2AICI_3](https://tex.z-dn.net/?f=%202Al%28s%29%20%2B%203Cl_2%28g%29%5Crightarrow%202AICI_3)
1) Moles of aluminum : ![\frac{0.824 g}{27 g/mol}=0.03052 mol](https://tex.z-dn.net/?f=%5Cfrac%7B0.824%20g%7D%7B27%20g%2Fmol%7D%3D0.03052%20mol)
According to reaction, 2 moles of aluminum gives 2 moles of aluminium chloride.
Then 0.03052 mol of aluminum will give with :
of aluminium chloride.
Mass of 0.03052 moles of aluminium chloride :
![0.03052 mol\times 133.5 g/mol=4.0744 g](https://tex.z-dn.net/?f=0.03052%20mol%5Ctimes%20133.5%20g%2Fmol%3D4.0744%20g)
4.0744 grams of aluminum chloride can be obtained.
2) Moles of Aluminium : ![\frac{0.194 g}{27 g/mol}=0.007185 mol](https://tex.z-dn.net/?f=%5Cfrac%7B0.194%20g%7D%7B27%20g%2Fmol%7D%3D0.007185%20mol)
According to reaction, 2 moles of aluminum reacts with 3 moles of chlorine gas.
Then 0.007185 mol of aluminum will react with:
of chlorine gas.
Mass of 0.01077 mol moles of chlorine gas:
![0.01077 mol\times 71 g/mol=0.7652 g](https://tex.z-dn.net/?f=0.01077%20mol%5Ctimes%2071%20g%2Fmol%3D0.7652%20g)
0.7652 grams of chlorine that react with 0.194 g of aluminum.

Answer:
Due to static charges.
Explanation:
In the illustration, we can see that when we bring the magnet close to the body, the static charges present on the body rearrange theirselves and attracted by the magnet. The magnetic substance is responsible for the arrangement of charges on the body and when they are arranged, they attract each other so we can say that static charges are present on the body and rearrangement occurs in the body.
Answer: 1.) renewable resources can be replenished as fast as they are used. Nonrenewable resources are unable to be replaced at the same rate at which they are used. 2.) nonrenewable energy sources will eventually run out, leaving people to figure out how to continue running their cars, homes, and busines. They must find alternative sources of energy. Since renewable energy resources that will never run out, it is a great option.
