Answer:
4
Explanation:
The equation for the reaction between bismuth(III) hypochlorite and acetic acid can be represented as:
Bi(ClO)₃ + 3CH₃COOH ------------------> Bi(CCH₃COO)₃ + 3 HClO
₃
Bi⁺³ + 3ClO⁻₃ + 3CH₃COO⁻ + 3H⁺-----------> Bi(CH₃COO)₃ + 3H⁺ + 3ClO
⁻₃
From the above reaction, we can therefore conclude that the free ions that are present at the product side of the total ionic concentration = 4.
Thus problem is providing us with the mass of iron (III) oxide as 12.4 g so the moles are required and found to be 0.0776 mol after the calculations:
<h3>Mole-mass relationships:</h3>
In chemistry, we use mole-mass relationships in order to calculate grams from moles and vice versa. In this case, since we are given the mass of iron (III) oxide as 12.4 g one can calculate the moles by firstly quantifying its molar mass:
Then, we prepare a conversion factor in order to cancel out the grams and thus, get moles:

Answer:
Explanation:
None of the statement is true for both chemical and nuclear reactions. In chemical reactions, mass is always conserved and the type of atoms are also conserved.
Answer:
Explanation:
A chemical reaction describes the reaction between reactants to produce products.
A chemical equation is represented as a reactant present on the left-hand side of the equation if two or more reactants are present they are separated by the "plus" sign.
On the right side of the equation product is written and if more than one product is formed then these are separated by "plus" sign as in the reactants.
The reactant and the products are separated by an arrow, the head of arrow is in the direction of the product when the reaction is irreversible.
In the case of reversible reactions or chemical reactions that are present in equilibrium, the reactant and product are separated by a double-headed arrow.
