Answer:
The answer to your question is 6
Explanation:
Data
Cu + 2AgNO₃ ⇒
To find the answer, count the number of each element in the reactants
Element Quantity
Copper 1
Silver 2
Nitrogen 1
Oxygen 6
Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.
The answer is false because receiving an electrical shock is not an example of a negative punishment if you forget to turn off the power.
For this, we use the Arrhenius equation to solve the problem. It is expressed as:
k = Ae^-(E/RT)
where k is the reaction rate, A is the pre-exponential factor, E is the activation energy and T is the temperature.
For a reaction, A is constant at different temperatures. We then isolate the constant and then introduce the second condition to the equation since it will still be equal to the constant. It is then simplified to:
ln(k2/k1) = -E/R (1/T2 - 1/T1)
ln(5.50k1/k1) = -51.64/8.314 (1/T2 - 1/343)
T2 = 379 K
