i found this the question is different but I think the situation is same
1. Air boiled out of water as steam is rich in ?
1 answer:
Answer:
<u><em>1. The air boiled out of water as steam is rich in water vapor, </em></u><em><u>H₂O</u></em><u><em>(g)</em></u>
<u><em></em></u>
<u><em>2. Benzene reacts with hydrogen in the presence of nickel catalyst at 180°C to give cyclohexane.</em></u>
Explanation:
<em></em>
1. When water boils liquid water passes to gaseous phase.
Water in gaseous phase is named water vapor or steam.
This happens around 100ºC, depending on the atmospheric pressure.
The air that is around the boiling water will carry that steam, becomind an air rich in water vapor, H₂O(g)
2. Benzene has chemical formula C₆H₆.
It is a cyclic unsaturated hydrocarbon. Benzene contains 3 double bonds.
When unsaturated hydrocarbons are heated in the presence of nickel catalyst, the double bonds are broken, forming single bonds and adding the needed hydrogen to the chain: one to each carbon that had a double bond transformed into single bond.
Thus, the product of the catalytic hydrogenation of benzene, C₆H₆, is cyclohexane, C₆H₁₂

<h3>What is pH?</h3>The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.
⇒pH = -log()
Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.
