Explanation:

If you know chemistry please be so kind and take some time to help me with these 2 problems!! Marking brainliest!!

Answers

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.

The law of conservation of mass is applicable to

Answers

Answer:

The law of conservation of mass states that in a closed system, mass is neither created nor destroyed during a chemical or physical reaction. The law of conservation of mass is applied whenever you balance a chemical equation.

Explanation:

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

It is applicable in a chemical when the the mass of the products in a chemical reaction is equal to  the mass of the reactants.

But it is not applicable in a nuclear fusion as some of the mass is generated as energy.

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.

A person purchases a bag of potato chips that was sealed in San Francisco, CA where the elevation is 50 feet above sea level and the air pressure is 1 atmosphere. They board an unpressurized airplane with the bag of chips and fly to an altitude of 8,000 feet where the air pressure is 0.75 atmosphere. What do you predict will happen to the bag of chips? (Must be Thoroughly thoughted and explanation)" I will Give Brainiest"

Answers

Hello, I Am BrotherEye

Answer:

As the atmospheric pressure decreases with increase in altitude, when a sealed bag of chips is taken to higher altitude then the pressure of the gases inside the bag become greater than the outer atmospheric pressure and apply pressure on the side covering of the chips bag due to which the chips bag expand.

Explanation:

Atmospheric pressure decreases with increasing altitude. Let's assume you tie up a bag at sea level altitude (with little air inside). That air inside the bag is at 1atm as long as you're at sea level.

Now you start going up, your altitude increases and atmospheric pressure decreases (remember what I said in the beginning about atmospheric pressure decreasing with increasing altitude?).

Let's say you reach an altitude where the atmospheric pressure is 0.5atm, the force acting inside the bag which is pushing it outward is now greater than the force acting on it which is pushing it inward (1atm>0.5atm). As a result, the air inside the bag will push the sides of the bag outward, thus inflating it to a point where the pressure inside the bag becomes 0.5atm or the bag stops stretching.

For the same reason, if you bring the same bag down and take it too deep into the earth (at an altitude lower than sea level) or if you inflate the bag at a very high altitude and bring it down to sea level, it will deflate.

Best Of Luck
