What’s the question Bc I don’t understand what u are trying to ask
Answer:
Explanation:
The chemical reaction of the well-balanced equation is as follows:

The aforementioned reaction's ionic equation is:

From above; Na⁺ and Cl⁻ appear on both sides;
Hence, the net ionic equation is:

Density measures how tightly packed opposed to how heavy like water is denser than oil.
Answer:
True.
Explanation:
Specific heat is the amount of heat required to raise one gram of a particular substance by one degree Celsius or Kelvin.
Formula for calculating specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.
= m * Cp * delta T
