Answer:
Option (D)
Explanation:
The river load is defined as the materials such as rock fragments, stones, sediments and other types of particles, which are carried by the river during its flowing stage. These particles are generally considered as the load.
A load of a river is often affected by the slope of the river, the shape of the river bed and the volume of water flow.
The slope of the river plays an essential role as the higher the slope, the higher will be the flow rate and more amount of sediments and rock fragments will be transported by the river.
The narrow type of rivers are generally faster and carries a larger amount of sediments in comparison to a broad river channel. Again, the more the volume of water flow in any river, the more it has the capacity to pick sediments and transports them from one place to another.
The lighter particles generally flow in suspension or solution, and the coarser particles are carried either by rolling, sliding and saltation process.
Hence, the correct answer is option (D).
C. buffering
D. half-reaction
the answer is oxidizing look it up
Also i took the test
Long story short, C is the answer.
c.
B. zinc and hydrogen carbonate.
C. zinc chloride and hydrogen.
D. zinc chlorate and water.
In the chemical reaction: Zn + 2HCl -> ZnCl₂ + H₂, the reactants are zinc, Zn and hydrochloric acid, HCl (Option A)
Chemical equations are representation of chemical reactions with symbols and formula of elements involved in the reaction.
Every chemical equation has two sides. These are:
With the above information, we can determine the reactants of the chemical equation. This is shown below:
Reactants => They are located on the left hand side of the equation
=> Zn and HCl
Thus, the correct answer to the question is: zinc and hydrochloric acid (option A)

Answer:
Option-B (Carbon and Silicon)
Explanation:
Among the given pairs only carbon and silicon have the most similar properties. This is because,
Sodium and Magnesium belong to different groups. Sodium present in Group I has one electron in its valence shell and capable of transferring only one electron while, Magnesium present in Group II have two electrons in its valence shell and is capable of donating two electrons. Hence, both show different properties.
Example:
2 Na + Cl₂ → NaCl
Mg + Cl₂ → MgCl₂
As shown in reactions when Sodium and Magnesium are treated with Cl₂ they give a products with different proportions.
Carbon and Silicon show almost same properties because both belong to Group IV hence both are capable of forming four bonds. Also, they share the same property of self linkage in making a long chains.
Argon and Chlorine also belong to two different groups. Argon is present in Group VIII (Noble Gases) and Chlorine is present in Group VII (Halogens). Hence, Argon is an inert specie which is non reactive while Chlorine gives different reaction easily.
Potassium and Calcium belong to different groups. Potassium present in Group I has one electron in its valence shell and capable of transferring only one electron while, Calcium present in Group II have two electrons in its valence shell and is capable of donating two electrons. Hence, both show different properties.
Example:
2 K + Cl₂ → KCl
Ca + Cl₂ → CaCl₂
As shown in reactions when Potassium and Calcium are treated with Cl₂ they give a products with different proportions.
