Agas occupies 12.3 liters at a pressure of 40.0 mmhg. what is the volume (in centiliters) when the pressure is increased to 60.0 mmhg?

820 cL

Explanation:

Boyle's Law

Relationship between the pressure and volume of a gas when the temperature is constant  (if we asume the temperature is constant)

It was discovered by Robert Boyle in 1662. Edme Mariotte also came to the same conclusion as Boyle, but he did not publish his works until 1676. This is the reason why in many books we find this law under the name of Boyle and Mariotte's Law.

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant.

As the volume increases, the particles (atoms or molecules) of the gas take longer to reach the walls of the container and therefore collide less times per unit of time against them. This means that the pressure will be lower since this represents the frequency of gas shocks against the walls.

When the volume decreases the distance that the particles have to travel is smaller and therefore more shocks occur in each unit of time: the pressure increases.

What Boyle discovered is that if the amount of gas and the temperature remain constant, the product of pressure by volume always has the same value.

As we have seen, the mathematical expression of this law is:

P * V = K

Where:

P: pressure

V: volumne

K: constant

Suppose we have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment. If we vary the volume of gas to a new V2 value, then the pressure will change to P2, and the following will be true:

P1 * V1 = P2 * V2

Calculation

P1 = 40 mmHg = 0.0526 atm

P2 = 60 mmHg = 0.0789 atm

V1 = 12.3 L

V2 = ?

V2 = (P1 * V1) / P2

V2 = (0.0526 atm * 12.3 L) / 0.0789 atm

V2 = 8.2 L = 820 cL

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
