Answer:Mixture
Explanation: It wouldn’t be a pure substance because it has non medical properties in it along with medical. It would be a mixture because of the mix of pure and non pure. (my opinión)
Answer: you cannot change the subscripts in a formula in order to balance a chemical equation because the subscripts indicate the number of each kind of atom in the formula,
Each compound has an invaraible chemical formula which tells how many atoms of every kind constitute the compound.
Varyng the subscripts is a modification of the chemical formula, meaning that you end up with a different compound.
On the other hand, by varying the coefficients, you only modifiy the number of unit formulas (number of molecules of the compound) that intervene in the reaction, which is what you want to indicate by balanceing reactants and products.
Answer:
Explanation:
First, convert the grams to moles, then convert moles to atoms.
1. Grams to moles
To convert from grams to moles, we use the molar mass. Phosphorus's molar mass is given to use.
- Phosphorus (P)= 30.97 g/mol
We can use this number as a fraction.
Multiply by the given number of grams (1.01)
Flip the fraction so the grams of phosphorus cancel out.
2. Convert Moles to Atoms
To convert from moles to atoms, we use Avogadro's Number.
This tells us the number of particles in 1 mole. In this case, it is atoms of phosphorus in 1 mole of phosphorus. We can create a fraction.
Multiply by the number of moles we calculated.
The moles of phosporus will cancel.
This is closest to 1.97*10²² atoms, so choice B is correct.
The oxidation number of Mn is 0. Details about oxidation number can be found below.
<h3>What is oxidation number?</h3>
Oxidation number is the hypothetical charge of an atom within a molecule.
However, when an atom exists independently as an element, the oxidation number of such element is 0.
The oxidation number is assigned to an atom in a element/compound. It can either be +, -, or 0 and it tells us if electrons are lost or gained.
Therefore, according to this question, the oxidation number of Mn is 0.

A chemical reaction involves the rearranging of atoms of the same or different elements to form new substances. It is represented by a chemical equation in which the reactants (substances that are broken apart) are written on the left and the products (new substances formed) are written on the right. If more than one reactant or product is needed, they are separated with a + sign. An arrow is used to separate the reactant side of the equation from the product side.
