I believe the answer is a covalent bond. :)
Answer:
The correct option is The net ionic equation shows the spectator ions in the reaction.
Explanation:
The net ionic reaction will show us the ions which are involved in the reaction. It also helps us the charges present on each atom and how a reaction occurs due to these charges on atoms. It shows us that which ions actually take part in a chemical reaction and which ions do not take part in the reaction and are involved only for balancing the equation.
Answer:
There are many items that could be altered to test the reaction of another. These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
Explanation:
The correct answer is 5819.04 J
The energy (q) required to elevate an object of mass (m) and specific heat capacity (c) by a temperature (T) is given by q = mcΔT.
Here, m is 72 g, c is 0.449 J/Kg °C, ΔT = 260 - 80 = 180 °C
Now, putting the values we get,
q = 72 × 0.449 × 180
q = 5819.04 J of energy is absorbed by the skillet.
