25.0g of Aluminum metal is combined with
45.Og Copper(ll) Chloride to produce Aluminum Chloride
and Copper metal
1. Write and balance the chemical equation.
2. Write the needed mole ratio between reactants.
3. What is the mole ratio you have from the data?
4. What is in excess and what is limited? (Show Work)
5. What is the theoretical yield of Aluminum Chloride?

Answers

Answer: 1. [tex]2Al+3CuCl_2\rightarrow 2AlCl_3+3Cu[/tex]

2. 3 moles of [tex]CuCl_2[/tex] : 2 moles of [tex]Al[/tex]

3. 0.33 moles of [tex]CuCl_2[/tex] : 0.92 moles of [tex]Al[/tex]

4. [tex]CuCl_2[/tex] is the limiting reagent and [tex]Al[/tex] is the excess reagent.

5. Theoretical yield of [tex]AlCl_3[/tex] is 29.3 g

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Al=\frac{25.0g}{27g/mol}=0.92moles[/tex]

[tex]\text{Moles of} CuCl_2=\frac{45.0g}{134g/mol}=0.33moles[/tex]

The balanced chemical equation is:

[tex]2Al+3CuCl_2\rightarrow 2AlCl_3+3Cu[/tex]  

According to stoichiometry :

3 moles of [tex]CuCl_2[/tex] require = 2 moles of [tex]Al[/tex]

Thus 0.33 moles of [tex]CuCl_2[/tex] will require=[tex]\frac{2}{3}\times 0.33=0.22moles[/tex]  of [tex]Al[/tex]

Thus [tex]CuCl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al[/tex] is the excess reagent.

As 3 moles of [tex]CuCl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]

Thus 0.33 moles of [tex]CuCl_2[/tex] give =[tex]\frac{2}{3}\times 0.33=0.22moles[/tex]  of [tex]AlCl_3[/tex]

Theoretical yield of [tex]AlCl_3=moles\times {\text {Molar mass}}=0.22moles\times 133.34g/mol=29.3[/tex]

Thus 29.3 g of aluminium chloride is formed.

Own words

Answers

Answer: Hotspot: A hotspot is a physical location where people can access the Internet, typically using Wi-Fi, via a wireless local area network (WLAN) with a router connected to an Internet service provider. ... While many public hotspots offer free wireless access on an open network, others require payment.

A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

Vinegar is a solution with a 3% mass of acetic acid. How much acid is in 550 g of vinegar?

16.5 g

10.5 g

4.5g

3 g

(show work and no links please)

Answers

*answer*

your answer will be 4.5 g

Explanation:

Vinegar is a solution with a 3% mass of acetic acid. How much acid is in 150 g of vinegar? (result: 4,5 g of acetic acid) solute acetic acid solvent water solution.

There are 16.5g of acid in 550 g of vinegar with a 3% mass.

HOW TO CALCULATE MASS:

According to this question, vinegar contains a 3% mass of acetic acid. This means that acetic acid is 3 out of 100 grams of vinegar.

If there are 550g of vinegar, this means that the mass of acetic acid in the vinegar is calculated as follows:

3/100 × 550

= 0.03 × 550

= 16.5g

Therefore, there are 16.5g of acid in 550 g of vinegar with a 3% mass.

What chemical reaction affects thermal energy?

Answers

The Heat of Reaction is the change in the enthalpy of a chemical reaction. In endothermic reactions, (ΔH>0) thermal energy is absorbed via the reaction.

1/5 divided by 3/4 fraction

Answers

Answer:

4/15

Explanation:

we can write out an equation by doing (1/5 ÷ 3/4) and then switch the sign to multiplication and we can keep the first fraction the same (in this case 1/5) and then we flip the second fraction BUT when we flip the second fraction upside-down we have to change the symbol to multiplication (1/5x4/3)

then after that all we do is multiply the denominators and numerators :)

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆

Answer and Explanation:

Solutions that have a pH of 8 would be considered a Weak Base.

This is because a weak base is a base that, upon dissolution in water, does not dissociate completely.

Solutions/liquids that have a pH higher than a pH of 7 are basic solutions, while solutions/liquids that have a pH lower than a pH of 7 are acidic solutions.

When the pH level is closer to 7, it is weak, and when it is far from 7, like if it is 1 or 12, then it is a strong acid/base.
