HELP . Read the following graduated cylinder.
Anon25 [30]

The volume of the liquid from the graduated cylinder is 22.5 mL

The last option (22.5 mL) is the correct option

The question seems to be incomplete

The image that completes the question is shown in the attachment below.

From the image, we observe that the liquid meniscus is between the 20 mL and 25 mL marks. That means the volume will lie in this range.

NOTE: The meniscus of a liquid is the upward or downward curve seen at the top of a liquid in a container.

The type of curve shown in the image is a concave meniscus and the volume of the liquid is read from the bottom of the curve.

To read the value from the graduated cylinder, we will first determine the difference between two consecutive lines. Between the 20 mL and 25 mL mark (two thick lines), we have 5 spaces separated by thin lines.

The measure between two consecutive lines is the difference between two thick lines divided by number of spaces between them

∴ The measure between two consecutive lines = (25mL - 20mL) ÷ 5

The measure between two consecutive lines = 5mL ÷ 5 = 1 mL

Now, to read the position of the liquid,

Starting from the 20 mL mark, the liquid exceeds two more lines + half way to the next line ( that is 2mL + 0.5 mL)

∴ The position of the liquid is 20 mL + 2mL + 0.5 mL = 22.5 mL

Hence, the volume of the liquid from the graduated cylinder is 22.5 mL

What is the effect of decreasing the volume of the reaction mixture? What is the effect of decreasing the volume of the reaction
fgiga [73]

Answer:

By decreasing the volume, the equilibrium will shift to the side with the smallest amount of particles

Explanation:

Step 1: Data given

The principle of Le Chatelier says:

When the volume is decreased, the equilibrium will shift to the side of the smallest number of particles.

2NOBr(g) ⇌ 2NO(g)+Br2(g)

In the following example, we have 2 moles of NOBr (on the left side) and 3 moles of gas on the right side. This means the left side, the reactant side, has the smallest number of particles.

The equilibrium will here shift to the left side, the side of NOBr.

In the following example

2NO2(g) ⇌ N2O4(g)

We have 2moles of NO2 on the left side and 1 mol of N2O4 on the right side.

By decreasing the volume, the equilibrium will shift to the side of the smallest number of moles. Here this is the right side, the side of N2O4.

If 4.5 mol of C6H8O7 react, how many moles of CO2 and Na3C6H5O7 will be produced?
Salsk061 [2.6K]

Answer:

A. 13.5 moles of CO2

B. 4.5 moles of Na3C6H5O7

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3NaHCO3(aq) + C6H8O7(aq) → 3CO2(g) + 3H2O(s) + Na3C6H5O7(aq)

A. Determination of the number of mole CO2 produced from the reaction. This is illustrated below:

From the balanced equation above,

1 mole of C6H8O7 reacted to produce 3 moles of CO2.

Therefore, 4.5 moles of C6H8O7 will react to produce = 4.5 x 3 = 13.5 moles of CO2.

From the above calculation, 13.5 moles of CO2 is produced

B. Determination of the number of mole of Na3C6H5O7 produced by the reaction. This is illustrated below:

From the balanced equation above,

1 mole of C6H8O7 produced 1 mole of Na3C6H5O7.

Therefore, 4.5 moles of C6H8O7 will also produce 4.5 moles of Na3C6H5O7.

Therefore, 4.5 moles of Na3C6H5O7 is produced from the reaction.
