Answer:
The statement best describes the reactants and products is :
A. Equal numbers of barium atoms are in the reactants as in the products.
Explanation:
The balanced equation is:
The law of conservation of Mass = It states that mass can neither be created nor destroyed in a chemical reaction.
Total mass of the reactant must be equal to total mass of the reactants.
Or
<u><em>Number of atoms of element in the reactant = number of elements in the product.</em></u>
Every equation in the universe must follow the law of conservation of Mass.
Now , consider the reaction
<u>Reactants ,</u> here are : Ba and O2
Number of Ba = 2
O = 2
Products = 2 BaO
Ba = 2x 1 = 2
O = 2 x1 = 2
Total number of Ba in both product and reactant = 2
Total number of O in both product and reactant = 2
So, Option A is correct.
Equal numbers of barium atoms are in the reactants as in the products.
Answer: The correct option is option d
Explanation - The mean deal with science is that it allows people to carry on research in an organized manner to find or make new discoveries and inventions.
The basic purpose of science is to try new things or ways to get an outcome by constant perseverance on research and negating the ways that don't work thus giving and improving knowledge of what is correct and what is not to make a new Discovery or invention.
fractional distilation because the solvent will evaporate and pass through the condenser and the sonvent will be in the beaker while the solute remains in the round bottomed flask
