Answer:
6 molecules of H2O are the maximum number.
Explanation:
From the drawing it can be seen that there are 6 H2 molecules and 3 O2 molecules reacting, which can be represented by the following chemical equation
6 H2 + 3 O2 ⇒ H2O
This equation is not balanced, so we proceed to balance it, being as follows:
6 H2 + 3 O2 ⇒ 6H2O
With which it can be determined that a maximum of 6 H2O molecules can be formed.

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.
AB + CD → AC +BD
The answer is A. The prokaryote...
