Where are the statements?
About 4 C to for water density until it is cooled
Answer:
is the overall voltage produced
Explanation:
Potassium and Tin are connected in an electrochemical series.
In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.
Here,
The voltage drop at potassium 
The voltage drop at Tin 
The net voltage

Answer:</h3>
CuO(s) + H₂(g) → Cu(s) + H₂O(l)
<h3>
Explanation:</h3>
- Assuming the reaction is the reduction of CuO by H₂
- Then the balanced equation for the reaction is;
CuO(s) + H₂(g) → Cu(s) + H₂O(l)
- The equation shows the reducing property of hydrogen gas, such that hydrogen reduces metal oxides such as copper(ii)oxide to the respective metals.
- The law of conservation requires chemical equations to be balanced so as the mass of reactants will be equal to that of products.
- In this case; there is 1 copper atom, 1 oxygen atom and 2 hydrogen atoms on both side of the equation and thus the equation is balanced.
