Answer:
M=0.380 M.
Explanation:
Hello there!
In this case, given those two solutions of aluminum bromide and zinc bromide, it is firstly necessary to compute the moles of bromide ions in each solution as shown below:

Now, we compute the total moles of bromide:

Then, the total volume in liters:

Therefore, the concentration of total bromide is:

Best regards!
Chemical symbols on the periodic table represent an element.
Answer: D. Na
Answer:
Ca Hso4 ×
Explanation:
Because i did whT you said
The reaction equation given is already balanced. So the ratio of the reactants and products is the same as the ratio of coefficients. Then the answer is 4 moles.
