Methanol (ch3oh) can react with oxygen gas to produce formaldehyde (h2co) and water. How many mole of formaldehyde can be produc
2 answers:
Answer: The quantity of moles for formaldehyde produced would equate to 4 moles.
Explanation:
For formaldehyde, the moles tally is 4.0 mole
The balanced chemical equation would be:
Through the analysis of the balanced equation, we find that
In this case, 2 moles of will react with 1 mole of
Thus, 4 moles of
will interact with
moles of
From this, it becomes clear that is the excess reactant since the provided moles exceed the those required while
is the limiting reactant, restricting the amount of product formed.
Next, we compute the moles of .
Because, 2 moles of yield 2 moles of
Consequently, 4 moles of will generate 4 moles of
Therefore, the total number of moles of formaldehyde formed will be 4 moles.

Answer:
The correct options include choice 2, 3, and 6.
Explanation:
Density is identified as the mass of a substance per unit volume occupied by that substance.
The density remains constant for a given substance, regardless of variations in mass and volume hence it is considered an intensive property.
2. 20.2 g of silver in 21.6 mL of water and 12.0 g of silver also in 21.6 mL of water.
3. 15.2 g of copper in 21.6 mL of water and 50.0 g of copper in 23.4 mL of water.
6. 11.2 g of gold in 21.6 mL of water and 14.9 g of gold in 23.4 mL of water.
The same metals in both instances will yield consistent densities due to the fixed density of the metal.
