6. How is the Law of Conservation of Mass evident in balancing chemical equations and solving stoichiometry problems?


Answer:

No Answer.

Explanation:

The law of conservation of mass dictates that the quantity of an element does not change over the course of the reaction. Therefore, a chemical equation is balanced when each element has equal numbers on both the left and right sides of the equation.


7. What steps must be performed before any stoichiometry problem is solved?


Answer:

balancing the equation, it gives you the correct number of moles of each element

12. Make 2 Word problems (with complete solution) about measurements on a PDF form or Powerpoint Presentation. pa help po sa word problems please <3


Answer:

1. James want to make an juice stand, he have 5500mL of juice, how will he know the Liter of the juice?

2. How many hours in 4 days?

solution:

1. in 1kg there are 1000mL.

5500mL÷1000mL=5.5L

therefore, James has 5.5L on his juice.

2. There are 24 hours in 1 day.

4×24=96

therefore, there are 96 hours in 4 day.


13. Problem Solving Sample Problem Using the stoichiometry sample problem 2.a. Find the percent yield of iron (Fe) if the reaction was able to produce 45.82g Percent Yield Formula: Actual Yield (g) Theoretical Yield (g) x 100 45.82g Percent Yield of Fe = 55.96g Percent Yield of Fe = 81.88% - x 100 Practice Problem Use your answer in practice problem for stoichiometry. Find the percent yield of Na2SO4 if the actual yield is 62.42g. Is the reaction successful or not?​


Answer:

To solve for the percent yield of Na2SO4, we need to know the actual and theoretical yields of the reaction. We can use stoichiometry to calculate the theoretical yield, and then use the percent yield formula to compute the percent yield.

Here is the balanced chemical equation for the reaction:

2 NaCl + H2SO4 → Na2SO4 + 2 HCl

From the balanced equation, we can see that 2 moles of NaCl react with 1 mole of H2SO4 to produce 1 mole of Na2SO4. Therefore, we can use the given mass of NaCl to calculate the theoretical yield of Na2SO4.

a. Calculate the theoretical yield of Na2SO4:

The molar mass of NaCl is 58.44 g/mol.

The mass of NaCl used in the reaction is not given in the problem, so let's assume it is 100 g for this example.

The molar mass of Na2SO4 is 142.04 g/mol.

From the balanced equation, 2 moles of NaCl react to produce 1 mole of Na2SO4.

Therefore, the number of moles of NaCl used in the reaction is: 100 g / 58.44 g/mol = 1.71 mol

The theoretical yield of Na2SO4 is: 1.71 mol NaCl x (1 mol Na2SO4 / 2 mol NaCl) x 142.04 g/mol Na2SO4 = 121.88 g

b. Calculate the percent yield of Na2SO4:

The actual yield of Na2SO4 is given as 62.42 g.

Using the formula for percent yield: Percent Yield = (Actual Yield / Theoretical Yield) x 100%

Substituting the given values: Percent Yield = (62.42 g / 121.88 g) x 100% = 51.16%

c. Determine whether the reaction was successful:

The percent yield of Na2SO4 is 51.16%.

A percent yield below 100% indicates that the actual yield is less than the theoretical yield, which could be due to experimental errors or incomplete reactions.

Therefore, the reaction was not completely successful, and there was a loss of product or reactants due to various reasons.

Explanation:


14. Problem Solving Example:Sample Problem Using the stoichiometry sample problem 2.a. Find the percent yield of iron (Fe) if the reaction was able to produce 45.82g Formula: Percent Yield = Actual Yield (g) ___________________Theoretical Yield (g) x 100 Percent Yield of Fe = 45.82g_______ x 10055.96gPercent Yield of Fe = 81.88% Practice Problem Use your answer in practice problem for stoichiometry. Find the percent yield of Na₂SO4 if the actual yield is 62.42g. Is the reaction successful or not?Answer:I hope someone can answer this question ​


To solve for the percent yield of Na₂SO4, we need to know the theoretical yield first. Let's use the same reaction from the stoichiometry practice problem:

2NaCl + H2SO4 → Na2SO4 + 2HCl

From the balanced equation, we can see that 2 moles of NaCl react with 1 mole of H2SO4 to produce 1 mole of Na2SO4. Using the given mass of NaCl, we can calculate the theoretical yield of Na2SO4:

Molar mass of NaCl = 58.44 g/mol
2 moles of NaCl = 2 x 58.44 g/mol = 116.88 g
Molar mass of Na2SO4 = 142.04 g/mol
1 mole of Na2SO4 = 142.04 g/mol
Theoretical yield of Na2SO4 = (1 mol Na2SO4 / 2 mol NaCl) x (116.88 g NaCl) x (1 mol Na2SO4 / 142.04 g Na2SO4) = 41.13 g Na2SO4

Now we can use the formula for percent yield:

Percent Yield = (Actual Yield / Theoretical Yield) x 100

Percent Yield = (62.42 g / 41.13 g) x 100 = 151.6%

A percent yield greater than 100% is not possible in reality, so there must have been an error in the experiment. The reaction is not successful.

Answer:

when your anxiety or stress appear

because of hallowsenation

Answer:

Having OFW parents as a student has a negative effect in creating and deepening a bond between a parent and his child. There may be communication between them but commonly it is only possible when they are only using the social media as a platform of communication. And in this way of talking/creating a bond, there is still a barrier that cannot defeat a proper family bonding like eating dinner, talking face to face, spending quality bond with each other, and many more that can be considered as a proper family bonding.
