They aren't actually placed into the atom, they surround it in the "electron cloud" but if you add electrons, the charge of your atom becomes negative. If your remove them, the charge becomes positive
Answer:
Explanation:
Hello,
In this case, we use the Boyle's law which allows us to understand the volume-pressure behavior as an inversely proportional relationship:
Thus, solving for the final volume, once the pressure changes, we obtain:
Best regards.
Answer:
When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water.
Hello, Brainly User!
A heterogeneous equilibrium reaction is when there are different phases in the reaction. An equilibrium reaction is a reaction that can go in both the forward and reverse directions, and the concentrations of the reactants and products remain the same.
So therefore, your answer is A. Heterogeneous!

From a chemistry book that I have read, it stated that
Barium Sulfate is so insoluble in water. Due to this, it is not toxic to humans
since it is not dissolved and absorbed by our body. In the other hand, Barium
Carbonate is slightly soluble in water making it toxic to us.
Answer:
Barium carbonate is soluble in plain water
