They can both be converted to each other. Hopefully this helps! :)<span />
Material C. the less dense is easier to move through than the more dense, so the light moves faster. Its like light moving through less dense glass, then moving through a more dense wall.
<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.
Answer:
Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H+ ions decreases and the pH of the solution increases towards 7. To make the pH change by 1, a tenfold dilution is required (eg adding 9 cm3 of water to 1 cm3 acid). The acid is becoming less acidic.
Similarly, when an alkali is diluted with water the concentration of OH- ions decreases. This causes the pH of the alkali to fall towards 7, making the solution less alkaline as more water is added.
Explanation:
Don’t currently have a calculator with me but just use Avogadros constant (A) 6.02x10^24, in the equation n=N/A. Lower case n being the number of mol and upper case being the number of molecules (given).
