Sodium + chlorine = sodium chloride
Answer:
The Gauge pressure at 9 meters depth is 
Explanation:
Gauge pressure is the difference between absolute pressure and some reference pressure, most commonly atmospheric pressure. The increment in pressure caused by a static fluid is given by:
where 
is the density of the liquid, g is the accleration due to gravity and d is the depth.
Now, we see that 
is linearly proportional to d, and we can assume that remains constant, because liquids are usually not compressible.
Given that the greater depth is simply 3 times the smaller depth:
at 
of depth will also be three times the gauge pressure at 
of depth.
We could also have calculated ny using:
and used this result to calculate the gauge pressure. These are both similar methods that yield the same result
Answer:
- <u><em>Option A) A gas was produced.</em></u>
Explanation:
Indeed, the production of a gas is an indication that a new substance was produced as result of the reaction of the matter that constitutes the antiacid tablet and the distilled water.
A chemical reaction is a change that yields the formation of new substances (products), due to the rearrangements of the atoms of the reactants.
In a very simple form, you can represent a chemical reaction by the general equation:
Which means that some elements or compounds, those in the reactant side of the equation, undergo a change in which some chemical bonds are broken, the atoms separate from the original substances and combine into a new arrangement in which they form one or more different substances (products).
The option B), that the table dissapeared is not a clear evidence of a chemical change because it could have been dissolved, which is a physical change.
Also, the option C), that there was a color change, cannot be cited as an evidence of a chemical reaction, since the color is a physical property.
As for the option D, that there was a change in mass, is not a viable option, since mass cannot change either with a chemical or physical change.
Answer:
24.6 - 11.2 / 4.4 = 3.045m/s
Explanation:
acceleration = vf-vi / time
vf= 24.6 m/s
vi= 11.2 m/s
t= 4.4s
