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!
Explanation:
All the points that are given below are true to have been affecting the war theory positively. The untimely and unnatural death that were happening earlier was prevented after introduction of germ theory and keeping a check on the germs that were inflicting death.
Also the accidental discovery of X-Ray helped the soldiers to get an overview of what was happening inside the body. The nuclear power plants help generate atomic energy and brought in the concept of nuclear weapons so did happen with atoms as well which lead to development atom bombs that were very useful in wars
The change in internal energy of the combustion of biphenyl in Kj is calculated as follows
=heat capacity of bomb calorimeter x delta T where delta T is change in temperature
delta T = 29.4 -25.8= 3.6 c
= 5.86 kj/c x 3.6 c = 21.096 kj
Answer:
Things catching on fire, buildings burning down, dangerous gasses, smoke.
