<h2>Answer:</h2>
In both glasses have juices of same mass. But the temperature is different due to which the kinetic energy of molecules in both glasses is different.
As kinetic energy is directly proportional to temperature.
To make the kinetic energy of the molecules equal she should:
- Heat one glass of 25°C to 40°C.
or
- Cool the juice of 40°C to 25°C
Answer:
I think its b
Explanation:
but I wouldn't depend on this answer
4. <span>The metals that would be able to reduce copper ions in solution would be hydrogen(H), lead(Pb), tin(Sb), nickel(Ni), iron(Fe), zinc(Zn), aluminum(Al), Magnesium(Mg), sodium(Na), calcium(Ca), potassium(K), and lithium(Li).
5. </span>If you had a house with both copper- and zinc-galvanized iron water pipes,zinc would be desirable because <span>A metal that is easily oxidized would rust more readily.</span><span>

Anything with a pH level of 3, 2, or 1.
Data Given:
Time = t = 30.6 s
Current = I = 10 A
Faradays Constant = F = 96500
Chemical equivalent = e = 63.54/2 = 31.77 g
Amount Deposited = W = ?
Solution:
According to Faraday's Law,
W = I t e / F
Putting Values,
W = (10 A × 30.6 s × 31.77 g) ÷ 96500
W = 0.100 g
Result:
0.100 g of Cu²⁺ is deposited.
