Describe how you could show that a compound is an acid

Answers

An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.

A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 273. kPa.
The piston is now pulled up, expanding the gas, until the gas has a final volume of 50.0 L. Calculate the final pressure of the gas. Be sure your answer has the
correct number of significant digits.

Answers

P2 = 54.6 kPa

Explanation:

Given:

V1 = 10.0 L. V2 = 50.0 L

P1 = 273 kPa. P2 = ?

We can use Boyle's law to solve this problem.

P1V1 = P2V2

Solving for P2,

P2 = (V1/V2)P1

= (10.0 L/50.0 L)(273 kPa)

= 54.6 kPa

Given the following equation: Na2O + H2O ---> 2 NaOH
How many moles of NaOH are produced from 1.02 moles of Na2O?

Answers

Answer:

2.04 moles

Explanation:

Since the ratio of Na2O to NaOH is 1:2, you multiply the number of moles by 2, equaling 2.04 moles.

(PLEASE HELP) 500 mL of a gas is collected at 745 mmHg. What will the volume be at 1.8 atm?

Answers

Answer:

272.22 mL

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new volume we have

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

First convert 745 mmHg to atm

760 mmHg = 1 atm

745 mmHg = 745/760 = 0.98 atm

We have

[tex]V_2 = \frac{500 \times 0.98}{1.8} \\ = 272.222...[/tex]

We have the final answer as

272.22 mL

Hope this helps you
