The cool people like me XD
Explanation:
Answer:
3.- The same
Explanation:
1.- In the reactants you need to calculate the charges that you have:
2 Al(s) = zero, because the aluminum is in it based formed (that mean without charge).
3 Cu2+ = 3 x 2+ = 6+ That is the total positive charges that copper collaborate in this reaction.
2.- Then calculate the charges on the products:
2 Al3+ = 2 x 3+ = 6+ charges from the aluminum.
3 Cu(s) = zero, because the copper in this case is in the base form
3.- In this way, the charges at the begging (6+) and at the end (6+) are the same.

Answer:</h3>
5 m/s²
<h3>
Explanation:</h3>
From the question, we are given;
- Mass is 3 kg
- Force is 15 N
We are supposed to calculate the acceleration;
- To calculate the acceleration we will use the second Newton's law of motion;
- According to Newton's second law of motion, the resultant force is directly proportional to the product of force and mass.
In this case;
To get acceleration we rearrange the formula;
a = F ÷ m
= 15 N ÷ 3 kg
= 5 m/s²
Therefore, the acceleration of the ball is 5 m/s²
The correct formula for carbon disulfide - CS2
Hope it helped!
