if i mix 4 grams of hydrogen and 32 grams of oxygen how many grams of water would be produced
I am taking the test and doesn't have an answer of 24 it has 28, 32, 36, and 4
The correct answer to this question would be 36 grams of water because hydrogen and oxygen make water.
To determine how many grams of water would be produced when hydrogen and oxygen combine, we need to consider the balanced chemical equation for the reaction.
2H₂ + O₂ → 2H₂O
From the equation, we can see that for every 2 moles of hydrogen (H₂) and 1 mole of oxygen (O₂), we obtain 2 moles of water (H₂O).
1 mole of hydrogen (H₂) weighs approximately 2 grams, while 1 mole of oxygen (O₂) weighs approximately 32 grams.
Therefore, to find out how many grams of water would be produced, we need to calculate the number of moles of hydrogen and oxygen and then use the mole ratio in the balanced equation to determine the moles of water.
First, let's convert the given masses of hydrogen and oxygen to moles:
Number of moles of hydrogen (H₂) = 4 grams / 2 grams/mole = 2 moles
Number of moles of oxygen (O₂) = 32 grams / 32 grams/mole = 1 mole
Using the mole ratio from the balanced equation (2H₂O : 2H₂), we can conclude that 2 moles of water are produced for every 2 moles of hydrogen.
Since we have 2 moles of hydrogen, we can expect 2 moles of water.
Finally, we convert the moles of water to grams:
Number of grams of water = 2 moles × 18 grams/mole (molar mass of water)
= 36 grams
Hence, when 4 grams of hydrogen and 32 grams of oxygen combine, 36 grams of water would be produced.
