The coefficients would be 2, 3, 2, and 4.
Explanation:
If we want to check this we would multiply the coefficient by each element. What we want is to have the same number of atoms on each side.
Reactant side:
# of carbon atoms: 2# of hydrogen atoms: 8# of oxygen atoms: 8Product side:
# of carbon atoms: 2# of hydrogen atoms: 8# of oxygen atoms: 8And that's it!

Which material has been recycled for over 3,000 years?
Answer:
plastic
Explanation:
How many moles of butane (C4H10(g)) were combusted in the presence of excess
oxygen gas if 55.8 L of water vapour at STP is collected?
Moles of Butane combusted : 0.4982
Further explanationGiven
55.8 water vapour at STP
Required
moles of Butane
Solution
Reaction(Combustion of Butane) :
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
1 mol at STP = 22.4 L, so mol of H₂O for 55.8 L :
=55.8 : 22.4
=2.491 moles
mol H₂O based on Butane as a limiting reactant(excess Oxygen)
From the equation, mol ratio Butane-C₄H₁₀ : H₂O = 2 : 10, so mol Butane :
[tex]\tt =\dfrac{2}{10}\times 2.491\\\\=0.4982[/tex]

Earth’s magnetic field is generated by a conducting fluid in its core. Explain why this is a theory.
Answer:
It's not a theory, The magnetic pull is from the core of the earth and pulls you down. example: I can jump and fall, Why? because of the core of the earth of me going p and then down. Why do you think that space doesn't have gravity? It's because it doesn't have a core, There are no planets that pull you down enough like earth.

Which of the following is not true about one mole?
the mass of 1 mole of carbon atoms = the mass of
1 mole of boron atoms
one mole contains 6.02 x 1023 particles
the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron
12 g of carbon equals one mole of carbon atoms
Answer:
A
Explanation:
Bc ik
The number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron is not true about one mole.
What element of one mole is false?It is untrue to say that one mole of fluorine gas weighs more than one mole of oxygen gas. Fluorine gas has a molar mass of 38 grams per mole, whereas oxygen gas has a molar mass of 32 grams per mole, based on their relative molar masses.
A mole of a substance is equal to 6.022 × 10²³ of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is referred to as "Avogadro's number" or "Avogadro's constant."
Since boron has a different molar mass than carbon, the statement that there are the same number of atoms in each mole is untrue.
The ratio of the substance's mass to its molar mass is used to express the number of moles of an element.
Moles = Mass/Molar mass
Given that the molar masses of carbon and boron differ, the statement that the number of atoms in a mole of carbon is equal to the number of atoms in a mole of boron is false.
Therefore, the correct answer is option c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron.
The complete question is:
Which of the following is not true about one mole?
a) the mass of 1 mole of carbon atoms = the mass of
b) 1 mole of boron atoms
one mole contains 6.02 x 1023 particles
c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron
d) 12 g of carbon equals one mole of carbon atoms
