Elements with the same number of electron shells are in the same (column)
Answer:
Scientific Question: ... I will boil water and add a substance like salt to see if the boiling point increases.
No, it doesn’t react to water.
We can achieve equilibrium state, when the concentration of product and reactants are equal to each other.
<h3>Describe this system when it reaches phase equilibrium?</h3>
In this type of system, when the same amount of liquid water is converted into gaseous form of water and the gaseous form of water into liquid form of water. This phase is known as equilibrium phase or state because same amount of reactants and products are produced .
So we can conclude that we can achieve equilibrium state, when the concentration of product and reactants are equal to each other.

Answer: 0.45 J / g °C
Explanation: solution attached.
Heat is equal to the product of mass, specific heat and change in temperature.
Q= mc∆T
Derive the equation to find c
c = Q / m∆T substitute the values
c = 21.6 J / 2.0g ( 24°C - 5°C)
c = 0.45 J / g ° C
