Answer:
Chemical
Explanation:
The change was chemical, because it can no longer be returned to the original form. You cannot get back the bubbles or fizz from the air.
The number of moles of hydrogen atoms contained in 1 mole of c6h12 is 12.
<h3>What is hydrogen made of?</h3>
Hydrogen can be produced from various domestic resources such as fossil fuels, biomass, and the electrolysis of water by electricity. The environmental sustainability and energy efficiency of hydrogen depends on how hydrogen is produced.
Hydrogen is the simplest element. Each hydrogen atom has only one proton. Hydrogen is also the most abundant element in the universe. Stars like the Sun are mainly made of hydrogen. The sun is essentially a giant sphere of hydrogen and helium gas.
Some facts about hydrogen:
- Hydrogen is the most abundant element on earth.
- Hydrogen is an alternative fuel with a very high energy content by weight.
- The fuel cell can be used to power multiple applications.
- Fuel cells are a clean way to generate electricity.
Fuel cell vehicles are very similar to traditional gasoline vehicles

They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon. During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other.

The balanced chemical reaction is written as:
P4 + 10Cl2 = 4PCl5
To determine the moles of PCl5 produced, we use the initial amount of the limiting reactant which is P4 and the relation from the reaction. We do as follows:
22.0 g P4 ( 1 mol / 123.90 g ) ( 4 mol PCl5 / 1 mol P4 ) = 0.7103 mol PCl5 produced
