Answer:
pH means power of hydrogen. 1.0 Click to let others know, how helpful is it it is a logarithmic scale used to determine acidity or basicity or aqueous solution. if pH value of a substance is 13 then it means that the substance is basic in nature.
The particles in gas collide less often as they are farther apart. that is the answer
<u>Answer:</u> The rate law for the given chemical equation is
<u>Explanation:</u>
Rate law is defined as the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in the given balanced chemical equation.
For the given balanced chemical equation:
Rate law expression for the reaction:
Order with respect to Li = 1
Order with respect to NaCl = 1
Hence, the rate law for the given chemical equation is
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.
That would be exothermic. Exothermic reactions are processes that release energy, usually in the form of heat or light. Energy is released because the total energy of the products is less than the total energy of the reactants.
