The correct answer here is A - An atom with a positive charge has more
protons than electrons. In the other instances the atom would have a
negative charge.
<u>Answer:</u> 3 moles of water are formed. The limiting reagent is Oxygen atom and the excess reagent is Hydrogen atom.
<u>Explanation:</u>
From the image provided, there are 8 moles of Hydrogen atom and 3 moles of Oxygen atom.
The equation for the formation of water is given by:
By Stoichiometry,
1 mole of Oxygen atom reacts with 2 moles of Hydrogen atom.
So, 3 moles of Oxygen atom will react with = of Hydrogen atom.
The required amount of Hydrogen atom is less than the given amount of Hydrogen atom, hence, it is considered as an excess reagent.
Therefore, Oxygen atom is the limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
1 moles of oxygen atom produces 1 mole of water molecule.
So, 3 moles of oxygen atom will produce = of water molecule.
Thus, 3 moles of water are formed. The limiting reagent is Oxygen atom and the excess reagent is Hydrogen atom.
Temperature has to be at least below 34° for snow to fall and it has to be a day where rain would fall
Earlier species thanks to evolution. hope this helped!
We use the given masses of the reactants to calculate the moles of Mn and Cl. Empirical formula represents the simplest mole ratio of atoms present in a compound.
Moles of Mn =
Moles of Cl = = 0.710 mol Cl
Simplest mole ratio:
So the empirical formula is
