How many moles of H2 will be produced from 100 moles of water?2 H2O → 2 H2 + O2

Chemistry

ki77a [65]1 year ago
7 0

In order to answer this question, we are going to look at the molar ratio between H2O and H2, we can see that by analyzing the numbers in front of the compounds, and we can see that the molar ratio is 2:2, this means that for every 2 moles of water decomposing, we will end up with 2 moles of H2 being produced, therefore the same amount of moles for H2O will be the same amount of moles of H2, which means that if we have 100 moles of H2O being decomposed, we will also have 100 moles of H2 being produced.

Is the equation balanced? Why or why not?
anygoal [31]

Answer:

Yes because the law of conservation of matter is followed. There are equal numbers of atoms of all elements in the

reactants and products.​

Explanation:

A balanced equation conform to the law of conservation of matter. While unbalanced equation suggests that matter has been created or destroyed.

Na3PO4 + 3KOH —> 3NaOH + K3PO4

A careful observation of the above equation proved that the equation is balanced is balanced because there are equal numbers of atoms of all elements in the

reactants and products.

Explain how scientific observations led to the development of, and changes to, the periodic table.
Vesna [10]
By the observations made by scientists on the properties of the elements that is found in the periodic table, these elements are arranged accordingly depending on their properties. The rows are called as the periods while columns are known as groups. In the case of the size of the atom, they are arranged in a way that from left to right across a period the atomic radius increases as well as going down a group. For reactivity, it increases from left to right and up to down. Also, the elements are arranged with respect to increasing atomic number. It is Dmitri Mendeleev that is one of the chemist  who arranged the periodic table which has been used up to till now.
