The chemical formula of water is written as H2O we can just use the ratio of the atoms since we are not given the reaction. Hydrogen is a diatomic substance so that it exists as H2. We calculate as follows:
0.253 mol H2O ( 1 mol H2 / 1 mol H2O ) = 0.253 H2 needed
Hope this answers the question. Have a nice day.
The answer is decomposition, ocean release and respiration. hope this helps u :D
Answer:
the friction?? or the movement
Explanation:
sense the salt is so light its easy to move
The maximum mass of B₄C that can be formed from 2.00 moles of boron (III) oxide is 55.25 grams.
<h3>What is the stoichiometry?</h3>
Stoichiometry of the reaction gives idea about the relative amount of moles of reactants and products present in the given chemical reaction.
Given chemical reaction is:
2B₂O₃ + 7C → B₄C + 6CO
From the stoichiometry of the reaction, it is clear that:
2 moles of B₂O₃ = produces 1 mole of B₄C
Now mass of B₄C will be calculated by using the below equation:
W = (n)(M), where
- n = moles = 1 mole
- M = molar mass = 55.25 g/mole
W = (1)(55.25) = 55.25 g
Hence required mass of B₄C is 55.25 grams.
