Answer:
Option B.
Explanation:
Obviously, a cleaning agent companies is going to be a producer of cleaning agents which are chemical substance which are used for the main purpose of removing unwanted particles (dirt).
For this particular Question, option ''B'' is correct because upon the addition of H2O, there will surely be changes in the numbers of ions in the cleaning agents.
From the Question above, we have that the cleaning agents has pH which is too high, therefore in order to reduce the pH of the cleaning agents, water will be used to mix the product or cleaning agents. Upon the addition of water there will be decrease in OH^-.
Answer:
Yes. These chemicals named barium chloride and calcium carbonate have been named properly. But silicon oxide has not been named correctly, an oxide of silicon is named as silicon dioxide not silicon oxide.
Explanation:
In chemistry while naming chemicals there are certain rules and naming the chemicals as per these rules is known as chemical nomenclature. The IUPAC's rule for chemical nomenclature of inorganic compounds can be read in a book named as red book.
<u>By sign convention, a cation is named first followed by an anion.</u> For example, in barium chloride (BaCl₂), barium which is represented by symbol Ba²⁺ is a cation and therefore written before chloride (Cl⁻) which is an anion. Similarly calcium carbonate is represented as CaCO₃.
As per the valency of silicon, it forms a dioxide with oxygen atom and it is represented as SiO₂.
By using ICE table:
CH3NH3+ + H2O → CH3NH4 2+ + OH-
initial 0.175 0 0
change -X +X +X
Equ (0.175-X) X X
when: Ka = Kw / Kb
= (1 x 10^-14) / (4.4 x 10^-4) = 2.3 x 10^-11
when Ka = [CH3NH42+][OH-] / [CH3NH3+]
by substitution:
2.3 x 10^-11 = X^2 / (0.175 - X ) by solving for X
∴ X = 2 x 10^-6
∴[OH-] = 2 x 10^-6
∴POH = -㏒[OH-]
= -㏒(2 x 10^-6)
= 5.7
when PH + POH = 14
∴PH = 14 - 5.7 = 8.3
You would expect 500 million atoms to be present. When a source experiences a half-life, it is a point in which atoms have degraded to half what they used to be in mass. 1/2(1 billion) = 500 million

Answer:
In the explanation
Explanation:
Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.
Convergent: When two plates are moving towards each other.
If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.
If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.
Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.
Hope this helps!
