PH + pOH = 14
pH + 0.253 = 14
pH = 14 - 0.253
pH = 13.747
[ H+] = 10 ^ -pH
[ H+ ] = 10 ^- 13.747
[ H+ ] = 1.790x10⁻¹⁴ M
hope this helps!
You have to use Dalton's law of partial pressure for this question. Dalton's law of partial pressure basically states that the total pressure of the system is all of the partial pressures of the components added together. Therefore to answer the question you just need to add all the patial pressures together meaning that the total pressure would be 700+500+500=1700.
The answer would be 1700 torr.
I hope this helps. Let me know if anything is unclear or if you have any further questions.
Due to heat , the kinetic energy of the atoms in the substance increases due to which they start vibrating vigorously and the inter-molecular attraction decreases and the substance increases in volume. For example, on boiling water...heat energy imparted makes the volume increase and finally turn into steam or water vapour in air.(The inter-molecular space in air is more than that in water.)
Answer:
Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.
<u>Answer:</u> The chemical equations are written below.
<u>Explanation:</u>
<u>For a:</u> Methane reacts with oxygen gas to produce carbon dioxide and water.
Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water
The chemical equation for the combustion of methane follows:
- <u>For b:</u> Butane reacts with oxygen gas to produce carbon dioxide and water.
This is also an example of combustion reaction.
The chemical equation for the combustion of butane follows:
- <u>For c:</u> An aqueous solution of sulfuric acid reacts with aqueous potassium hydroxide to produce potassium sulfate and water.
When an acid reacts with a base, it leads to the formation of salt and water. This reaction is known as neutralization reaction
The chemical equation for the reaction of potassium hydroxide and sulfuric acid follows:
Hence, the chemical equations are written above.
