Identify the substances in this reaction:
lukranit [14]

Answer:

is an aqueous reactant

is a liquid product

is a gaseous product

Explanation:

H_2CO_3 ⇔ CO_2 + H_2O

Hydrogen carbonate dissocates to form carbon dioxide and water. The acid (hydrogen carbonate) is in aqueous form and it dissociates to water (liquid) and carbon dioxide (a gas). It is also seen that the hydrogen carbonate is on the reactant side and it dissociates to produce water and carbon dioxide.

WH_2CO_3<u> is an aqueous reactant</u> (a reactant undergoes changes in a chemical reaction

<u />H_2O<u> is a liquid product</u> (product refers to the species produced from  chemical reaction)

<u />CO_2<u> is a gaseous product</u>

_____ The primary function of molecular membranes is the transport of ions and molecules into and out of cells. The movement of
ale4655 [162]
<h2>Active Transport </h2>

Explanation:

  • A cell uses energy for the movement of substances against a concentration gradient or an electrochemical gradient that maintains a balanced concentration of ions and molecules in living cells.
  • This transport of substances is known as Active transport mechanisms which are the basic function of the cell membranes.
  • The energy used is in the form of ATP.  
  • Active transport occurs when there is a difference in the concentration of particles on both sides.

Make the equation equal<br> Fe(NO3)3+KSCN —&gt; Fe(SCN)3 + K(NO3)3
Advocard [28]

Answer:

Fe(NO₃)₃ + 3KSCN  →   Fe(SCN)₃ + 3KNO₃

Explanation:

Chemical equation:

Fe(NO₃)₃ + KSCN  →   Fe(SCN)₃ + KNO₃

Balanced Chemical equation:

Fe(NO₃)₃ + 3KSCN  →   Fe(SCN)₃ + 3KNO₃

Type of reaction:

It is double displacement reaction.

In this reaction the anion or cation of both reactants exchange with each other. In given reaction the cation Fe⁺³ exchange with cation K⁺.

The given reaction equation is balanced so there are equal number of atoms of each elements are present on both side of equation and completely hold the law of conservation of mass.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.
