Answer:
65.712 grams of oxygen has reacted.
Explanation:
Mass of acetylene = 21.39 g
Moles of acetylene =
According to reaction , 2 moles of acetylene reacts with 5 moles of oxygen gas.
Then 0.8214 moles of oxygen gas will react with :
of oxygen gas.
Mass of 2.0535 moles of oxygen gas :
2.0535 mol × 32 g/mol = 65.712 g
65.712 grams of oxygen has reacted.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
</span><span>7.5 X10^23 molecules of H2SO4 ( 1 mol / 6.022x10^23 molecules ) (98.08 g / 1 mol ) = 122.15 grams H2SO4</span>
Pericles was more of politician while Confucius has been classified by many as a philosopher. The idea that they had different positions and were from very different parts of the world made them very distinct figures. Pericles was more academic and war oriented focusing on establishing sound social and political structures. Confucius promoted the goodness in people and the service to others as a way to be spiritually free.

Explanation:
The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be <u>(tetra phosphorus decoxide)</u>
<u />
Chemical element symbols, numbers, and other symbols, such as parentheses, dashes, brackets, commas, plus as well as minus signs, are used to represent the chemical quantities of the atoms that make up a certain chemical compound and molecule.
It is given that the number of P atom is 4 and 10 oxygen . Decoxide mean
any oxide with ten oxygen molecules per molecule.
Typically, a molecular molecule consists of two or even more nonmetal components. Molecular compounds are characterized by employing the stem of the primary element's term plus the suffix -ide, followed by the second element. The count of atoms in a molecule is specified using numerical prefixes.
Therefore, The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be <u>(</u><u>tetra phosphorus decoxide)</u>
