There are 15 atoms in magnesium acetate
Answer:
a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.
b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.
c = The reaction which involve the oxidation reduction are called redox reaction.
The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Chemical equation:
Zn + 2H⁺ → Zn²⁺ + H₂
a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.
b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.
Redox reaction:
The reaction which involve the oxidation reduction are called redox reaction.
The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.
Answer:
i already commented it but i want points anyways its 80 because 20x4 = 80. it said one gram equals 4 calories and there is 20 grams so basically 4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4
<u>Answer:</u>
<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>
<u>Explanation:</u>
<em>Given that the pH of the solution of HCl in water is 2.5.</em> Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. ions contribute to a solution’s acidic nature and contribute to a solution’s basic nature.
The equation connecting the concentration of and pH of a solution is pH=

<em>When the pH is </em>
<em>On dilution the concentration of a solution decreases and volume increases.</em>
