Answer:
126.0g of water were initially present
Explanation:
The electrolysis of water occurs as follows:
2H₂O(l) ⇄ 2H₂(g) + O₂(g)
<em>Where 2 moles of water produce 2 moles of hydrogen and 1 mole of oxygen.</em>
<em />
To find the mass of water we need to determine moles of oxygen and hydrogen, thus:
<em>Moles Hydrogen:</em>
14.0g H₂ ₓ (1mol / 2g H₂) = 7 moles H₂
<em>Moles Oxygen:</em>
112.0g O₂ ₓ (1mol / 32g) = 3.5 moles O₂
Based on the chemical equation, the moles of water initially present were 7 moles (That produce 7 moles H₂ and 3.5 moles O₂). The mass of 7 moles of H₂O is:
7 moles H₂O * (18g / mol) =
<h3>126.0g of water were initially present</h3>
Explanation:
a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
The appropriate response is oxygen. Cellular respiration is the procedure cells use to make vitality. Cells in our body join glucose and oxygen to make ATP and carbon dioxide. Oxygen is utilized as an electron acceptor inside the electron transport tie of vigorous breath to create adenosine triphosphate or ATP. This compound is a fundamental part in intracellular vitality exchange.
