Which is TRUE of the reactants in this displacement reaction? Fe + 2HCl FeCl2 + H2

Chemistry
2 answers:
Anna35 [415]4 years ago
7 0

Answer: Option (A) is the correct answer.

Explanation:

A displacement reaction is defined as a reaction in which an element reacts with a compound and an element of the compound is displaced by another element.

For example, Fe + 2HCl \rightarrow FeCl_{2} + H_{2}

In this reaction, there are one Fe atom, 2 hydrogen and 2 chlorine atoms on the reactant side.

Since, it is a chemical reaction therefore, properties of both reactants and products will be different.

Species present on the left side of arrow are reactants and on the right side of arrow depicts products.

Thus, we can conclude that the statement reactants are located to the left of the arrow in the chemical equation, is true.

Which of the following soils is the most porous? Soil A - flat, sorted particles. Soil B - round, sorted particles Soil C - roun
Ksju [112]

Answer: Option (b) is the correct answer.

Explanation:

Porosity means the ease with which a fluid can pass through between a rock or cracks etc.

If particles of a soil are flat and even if they are sorted then there will rarely be any space available for fluid or water to pass through it.

If soil particles are round in shape and are sorted then there will be space available for the fluid to pass through it. Hence, this type of soil will be most porous.

Similarly, if soil particles are round but are unsorted then there will be less space available as compared to sorted particles. This is because particles are placed randomly so, somewhere there will be much less space and somewhere there will be large space available. As a result, soil will not be most porous.

If soil particles are flat and unsorted then there will also be less space available for the fluid to pass through it. Thus, soil will be less porous.

Hence, we can conclude that out of the given options, soil B - round, sorted particles is the most porous.

Consider the following equilibrium reaction having gaseous reactants and products.
soldi70 [24.7K]

Answer:

The volume of hydrochloric acid increases.

Explanation:

  • Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

  • Increasing the volume of water vapors:

will increase the the concentration of the products side, so the reaction will be shifted to the left side (backward) to suppress the increase in the concentration of water vapors by addition.

So, The volume of hydrochloric acid increases, the rate of backward reaction increases, the rate of forward reaction decreases, and the volume of chlorine decreases.

<em>So, the right choice is: The volume of hydrochloric acid increases.</em>
