Answer:
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
Explanation:
The most likely reaction is a <em>double displacement</em>, in which Cu and H trade partners.
This gives
CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
The equation is already balanced, so no further work is necessary.
Answer:
Electric current
Hydrogen and oxygen gas
Explanation:
Electrolysis is defined as a method of separation whereby an electric current is introduced into compounds to separate them . The electric current used here is a direct electric current (DC) and it makes the compound to be spit into its' component elements.
Now, in the case of water like it says in the question. Water is a mixture of hydrogen and oxygen gas. Thus, when electric current is passed through water which has an Electrolyte, it makes the water to decompose into its compound elements which are hydrogen and oxygen.
For the hypothesis put what you think will happen
The right subject for this question is physics.
To calculate the work you use the formula:
Work = force * displacement
Work = 2500 pounds * 30 feet = 75,000 pounds - feet
To calculate the power you use the formula:
power = work / time
Power = 75,000 pound - feet / 30 seconds = 2300 pound-feet / second.
