Answer:
What happens when Chlorine reacts with Bromine
Explanation:
Both of them are electronegative and need 1 electron to achieve a fully filled electronic configuration.... When chlorine reacts with sodium bromide, we get a displacement reaction, in which chlorine will replace bromine. The balanced chemical reaction is: That is, we end up with sodium chloride and bromine.
Physical changes: breaking sticks, boiling the water
chemical changes: lighting the fire
(Breaking the wood does not change the substance of the wood , therefore it's a physical change. Water changing between solid, liquid, and gas form is always a physical change.)
Answer:
A) ascend using my buddy's alternate air source / make a controlled emergency swimming ascent
Explanation:
When it is found that you are out of air while under water, first of all don't panic, look for your buddy. If you are unable to do that so, then you need to make an emergency ascent. First try to make a <u>Controlled Emergency Swimming Ascent</u> (CESA). This ascent remains under control and is performed at a safe ascent rate. As you ascend the air in your lungs will expand with decreasing ambient pressure. To avoid an over pressurization injury, always exhale a continuous string of bubbles while going up.
If you are not sure you will make to the surface that leading to inhale the only option is to turn the CESA into a Buoyant Emergency Ascent. To be ready locate your weight system as you ascend. As an addition remove the weight from one of weight pockets and hold it away from your body in preparation of dropping if necessary. Dropping the weight will give you an upward buoyant force which is an <u>uncontrolled buoyant emergency ascent</u> and <u><em>should be performed only as the last option</em></u>.
So, according to this, first, always have a look at your SPG. Then, if you are out of air, look for your buddy, if not found then make CESA and the last option will be buoyant emergency ascent.
