Answer
12
Explanation
We have a balanced chemical equation from the question that depicts the formation of water.
2H2+O2-->2H2O,
We can clearly see from the equation that, the formation of 2 moles of water molecules requires the input of 2 moles of hydrogen and 1 mole of Oxygen.
So indirectly, it tells that the moles of water molecules will be double of the moles of Oxygen molecules used in the reaction.
So if we say that 6 moles of oxygen is used and the reaction is going in such a way that hydrogen is not a limiting reactant, then 12 moles of water will be produced.
Hope it help!
40. Because sodium chloride is NaCl
Your answer is: C. Neutrons are inside the nucleus of a atom
Answer:
1) correct
2) incorrect
3) correct
4)incorrect
Explanation:
1) A Lewis acid is a substance that accepts a nonbonding pair of electrons.
A Bronsted-Lowry acid is a substance that donates a proton H⁺
Since the donation of a proton involves the acceptance of a pair of electrons, every Bronsted-Lowry acid is also a Lewis acid.
2)A Lewis acid not necessarily needs to have a proton to be donated.
3) Conjugated acids of weak bases are strong acids and conjugated acids of strong bases are weak acids.
4)K⁺ comes from a strong base, therefore is does not have an acidic behaviour.
The answer is B. The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.
