Our balanced equation is Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag.

The coefficients of reactants tell us that 1 mole of Cu reacts per 2 moles of AgNO₃. We want to know the mass of Cu that will react with a mass (specifically, 420 g) of AgNO₃. To start, we must convert the mass of AgNO₃ to moles of AgNO₃:

Moles of AgNO₃ = Mass of AgNO₃ ÷ Molar Mass of AgNO₃

Moles of AgNO₃ = 420 g AgNO₃ ÷ 169.88 g AgNO₃/mol AgNO₃

Moles of AgNO₃ = 2.47 moles of AgNO₃.

Since only half as many moles of Cu is consumed in reacting with the AgNO₃, the number of moles of Cu that will react with 2.47 moles of AgNO₃ would be half of 2.47, or 1.24 moles of Cu.

Finally, we can convert the molar quantity of Cu to mass by multiplying the number of moles of Cu by the molar mass of Cu:

Mass of Cu = Moles of Cu × Molar Mass of Cu

Mass of Cu = 1.24 moles Cu × 63.546 g Cu/moles Cu

Mass of Cu = 78.6 g of Cu

So, 78.6 grams of Cu are needed to react with 420 g of AgNO₃.

---

The way to solve the second question is identical to how we solved the first question. The coefficient of Ag is 2, so the molar ratio between the Ag produced and Cu reacted is 2:1. In other words, half as many moles of Ag produced is equivalent to the number of moles of Cu that was consumed in the reaction.

So, as we did with the first question, we first convert the mass of the Ag produced to moles. The molar mass of Ag is 107.8682 g/mol. Dividing 98.5 g of Ag by the molar mass gives us 0.913 moles of Ag produced. The number of moles of Cu that reacted to produce 0.913 moles of Ag would be 0.913/2 = 0.457 moles of Cu.

Lastly, multiplying 0.457 moles of Cu by the molar mass of Cu, we obtain the mass of Cu (in grams) that reacted: 0.457 × 63.546 = 29.0 g of Cu.

So, 29.0 grams of Cu reacted to produce 98.5 grams of Ag.

Note: I have provided the answers for both questions to three significant figures; while 420 technically has only two significant figures, it would seem consistent to treat it as having three since 98.5 has three digits and three significant figures.

Explain why the properties of metals, ceramics, semiconductors, polymers, and composites need to be considered before decisions are made about which types of materials are used in a product. Enter your answer in the space provided.

Answers

Answer:

See explanation

Explanation:

In different products, different properties are desired based on the intended use of the final product.

The properties of the final product depends highly on the properties of the materials from which it was made.

For instance, when we desire a light weight product which is corrosion resistant and maintains a high tensile strength, we may consider the use of composite materials since they exhibit such properties.

Hence, the producer must consider the properties of each particular material before it is used in a product.

Explanation:

The initial pressure of a balloon floating in the air is 0.53 atm. After the balloon has reached a certain point in the sky, the volume of the air particles in the balloon is 4.3 liters at a final pressure of 0.42 atm. What was the initial volume of the balloon?

Answers

Answer:

The initial volume of the balloon is 3.41 L.

Explanation:

The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.

As the volume increases, the gas particles (atoms or molecules) take longer to reach the walls of the container and therefore collide with them fewer times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law which says:

"The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure"

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

or P * V = k

Now it is possible to assume that you have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1 * V1 = P2 * V2

In this case:

P1= 0.53 atmV1= ?P2= 0.42 atmV2= 4.3 L

Replacing:

0.53 atm* V1= 0.42 atm* 4.3 L

Solving:

[tex]V1=\frac{0.42 atm* 4.3 L}{0.53 atm}[/tex]

V1= 3.41 L

The initial volume of the balloon is 3.41 L.

the equation demonstrates a reaction of sodium chloride and fluorine. 2NaCl+F2=2NaF+Cl2. in order for the reaction to proceed, for every two moles of sodium chloride, there must be at least how many mole(s) for fluorine

Answers

Answer: You would need 1 mole of Fluorine

Explanation:The equation is already balanced so just looking at the coefficients in the equation we can see that Sodium Chloride (2NaCl) needs two moles for this equation and fluorine (F2) only needs one.

In order for the reaction to proceed, for every two moles of sodium chloride, there must be at least  1 mole for fluorine.

Balanced chemical reaction:

2NaCl +  F₂ → 2NaF + Cl₂

The reaction given above is balanced. When 2 moles of sodium chloride reacts with 1 mole of fluorine produces 2 moles of sodium fluoride and 1 molecule of chlorine.

Thus, two moles of sodium chloride, there must be at least  1 mole for fluorine.
