Answer:
All elements are neutral
Explanation:
The plum pudding model of the atom indicated that all elements are neutral. The model was proposed by J.J Thomson after he conducted his experiment on the gas discharge tube.
From the experiment he discovered electrons which he called cathode rays.
Therefore, he suggested the plum pudding model of the atom.
The model describes negatively charge sphere surrounded by positive charges to balance them.
If theres a mixture of components we can calculate the mole fraction
mole fraction can be calculated as follows
mole fraction of component =
number of moles of ethanol - 3.00 mol
total number of moles in mixture - 3.00 + 5.00 = 8.00 mol
mole fraction of ethanol =
mole fraction of ethanol is 0.375
Answer is: There are more reactants and one product of the reaction. The reactants may be elements or compounds. The product is always a compound.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
For example, balanced chemical reaction: Ba + F₂ → BaF₂.
In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
Second chemical reaction: CaO(s) + H₂O(l) → Ca(OH)₂(aq).
One molecule is produced from two molecules.
