Answer:</h3>
The equation is balanced since the number of atoms of each element are equal on both side of the equation.
<h3>
Explanation:</h3>
- Balancing chemical equations involves putting coefficient on the reactants and products of a chemical reaction.
- It results to equal number of atoms of each element on either side of the equation.
- A balanced chemical equation obeys the law of conservation of mass such that the mass of reactants is equal to the mass of products.
- The equation; 4AI(s) + 3O₂(g) → 2AI₂O₃(s) is balanced since the number of atoms of each element are equal on both side of the equation.
- That is, 4 aluminium atoms and 6 oxygen atoms on both side of the equation.
The basic unit of mass in the metric system is grams
Answer:
Explanation:
Hello!
In this case, since the formula for the calculation of molarity is defined in terms of moles and volume in liters as shown below:
Whereas the moles are computed by considering the molar mass of CaCO3 (100.09 g/mol):
Thus, we obtain:
