A dilute acid solution is prepared by adding the concentrated acid to water. If you do the reverse, i.e. add water to the acid it is possible that a small amount water could react with acid and boil and explode thus splashing the acid onto you or someone else near the activity.
Answer:
CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.
Explanation:
- It is a replacement reaction, that cations and anions are replaced with each other.
So, it gives CaSO₄ and CuCl₂.
- To balance the reaction, we apply the law of conversation of mass, that the no. of atoms in the reactants side is equal to that in the products side.
So, the balanced reaction is:
<em>CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.</em>
The answer is 656.18
6.02 x 109 = 656.18
Answer:
The answer to your question is: number 1
Explanation:
Third law of Newton: says that for every action ,there is an equal and opposite reaction.
So, if the child is pushing an object to the right, it will recipe the same amount of force that he is exerting to the object but in opposite direction.
Number 2 and 3 are incorrect because, because the third law of Newton says "an equal and opposite reaction", not slightly more or less.
Number 4 is wrong, it is not in agreement with Newton's third law of motion.
