Answer:
The submarine will rise.
Explanation:
To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.
Happy Hollidays!! :)
Volume of the peat moss = 
= 
Convert the above volume into 
Thus, volume in is:
Volume of peat moss = 
= 
Now,
Total volume by using area and depth of the peat moss = 
= 
= 
Convert above values in 
to get the value of volume in :
Thus, volume in is:
Total volume = 
= 
= 
Now, number of bags is calculated by the ratio of total volume of the peat moss to the volume of the peat moss.
Substitute the values of volume in above formula:
= 
≅ 
bags
Thus, number of bags of peat moss are needed to cover an area measure 
by 
to a depth of 
are bags.
Answer: The electronic configuration of iron is: Ar3d64s2. the two electrons in the 4s orbital are paired, and two of the electrons in the 3d orbitals are paired leaving four unpaired electrons.
Explanation:
0.29 M ammonia + 0.38 M ammonium bromide and 0.22 M hypochlorous acid + 0.18 M hydroiodic acids of aqueous solutions are good buffer systems.
<h3>Buffer Systems:</h3>
A solution that resists pH change when acids or bases are added to it is referred to as a buffer system. Either a weak acid and its salt, or a weak base and its salt, make up buffer systems. The ratio of HX/X- does not considerably alter when an acid or a base is introduced to a buffer.
Solutions known as buffers withstand pH changes when an acid or base is added. A weak base (A) and its conjugate weak acid (HA) are both present in buffers. When a reactive system is in equilibrium, adding a strong electrolyte with one common ion will cause the equilibrium to shift, lowering the concentration of the common ion. Buffers differ from one another in terms of pH range and buffer capacity.
