Answer:

A gas that exerts a pressure of <u><em>583.33 psi.</em></u> psi in a container with a volume of 12.45 L will exert a pressure of 1112 psi when transferred to a container with a volume of 6.531 L.

Explanation:

Initial pressure exerted by the gas = P_1

Initial volume occupied by the gas = V_1=12.45 L

Final pressure exerted by the gas = P_2=1112 psi

Final volume of the gas occupied by the gas = V_2=6.531 L

Applying Boyle's law:

P_1\times V_1=P_2\times V_2

P_1=\frac{P_2\times V_2}{V_1}=\frac{1112 psi\times 6.531 L}{12.45 L}=583.33 psi

The initial pressure exerted by the gas was 583.33 psi.

A gas that exerts a pressure of <u><em>583.33 psi.</em></u> psi in a container with a volume of 12.45 L will exert a pressure of 1112 psi when transferred to a container with a volume of 6.531 L.

Here, we may apply Boyle's law, which is mathematically expressed as:
PV = constant
So, we equate the product of the the initial pressure and volume to the product of the final pressure and volume as such:
P * 12.45 = 1112 * 6.53
P = (1112 * 6.53) / 12.45
P = 583.2 PSI

You need to prepare 1 L of the citric acid/citrate buffer. You have chosen to use Method 1 (see lab presentation). Calculate the
prisoha [69]

Answer:

3.11 is the pH of the buffer

Explanation:

The pH of a buffer is obtained using H-H equation:

pH = pKa + log [Conjugate base] / [Weak acid]

<em>Where pH is the pH of the buffer, pKa = -log Ka = 3.14 for the citric buffer and [] could be taken as the moles of each species.</em>

The citric acid,HX (Weak acid), reacts with NaOH to produce sodium citrate, NaX (weak base) and water:

HX + NaOH → H2O + NaX

That means the moles of NaOH added = Moles of sodium citrate produced

And the resulitng moles of HX = Initial moles - Moles NaOH added

<em>Moles HX and NaX:</em>

Moles NaOH = 0.100L * (0.65mol / L) = 0.065 moles NaOH = Moles NaX

Moles HX = 0.300L * (0.45mol / L) = 0.135 moles HX - 0.065 moles NaOH = 0.070 moles HX

Replacing in H-H equation:

pH = 3.14 + log [0.065mol] / [0.070mol]

pH = 3.11 is the pH of the buffer

This is the balanced reaction equation for the combustion of methane.

Explanation:

The Law of Conservation of Mass basically states that matter can neither be created nor destroyed. As such, we must be able to show this in our chemical reaction equations.

If you look at the equation above, you'll see an arrow that separates the reaction equation into two parts. This represents the direction of the reaction.

To the left of the arrow, we have our reactants.

To the right of the arrow, we have our products.

The quantity of each individual element in the left must equal the quantity of each individual element in the right.

So if you look below, you'll see the unbalanced equation, and I'll try to explain how to balance the reaction.

C

H

O

H

O

Our reactants in this equation are  

C

H

4

and  

O

2

.

Our next step is to break these down into individual atoms.

We have:

1 C atom, 4 H atoms & 2 O atoms.

If you're confused by this, look to see the little number to the bottom right of each element, the subscript, and it tells you how many of each atom are in the molecule. Make sense?

Now we look to the other side of the equation.

Here we see our products are  

C

O

2

+  

H

2

O

Again, we break these down into individual atoms again.

We have:

1 C atom, 2 H atom, 3 O atom
