The correct answer is C: Calcium carbonate in water is a solution
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.

Answer:
2.59g
Explanation:
Using Avagadro's law equation as follows:
V1/n1 = V2/n2
Where;
V1 = initial volume (litres)
V2 = final volume (litres)
n1 = first amount of gas in grams
n2 = second amount of gas in grams
According to the information provided in this question, v1 = 93.2L, v2 = 10.4L, n1 = 23.2 g, n2 = ?
Using V1/n1 = V2/n2
93.2/23.2 = 10.4/n2
Cross multiply
93.2 × n2 = 23.2 × 10.4
93.2n2 = 241.28
n2 = 241.28/93.2
n2 = 2.588
n2 = 2.59g

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.
