Some physical properties of the compound are related in this way.
Molecular mass of the compound, depends on the atomic masses of the elements.
Wether the compound is ionic or covalent depends on the nature of the bonds which depends on the electronic configuration of the elements.
Boiling pont depends, solubility, melting point and others depend on the strength of the bonds, wich depends on the electronic configuration of the elements.
So many other properties also are determined by the properties of the elements and the bonding of them to form the compound.
Solubility of the compound depends on
It’s probs a because 75-25 is 30 so it’s probs 30°C
Answer:
Q = 8.8 kJ
Explanation:
Step 1: Data given
The specific heat of a solution = 4.18 J/g°C
Volume = 296 mL
Density = 1.03 g/mL
The temperature increases with 6.9 °C
Step 2: Calculate the mass of the solution
mass = density * volume
mass = 1.03 g/mL * 296 mL
mass = 304.88 grams
Step 3: Calculate the heat
Q = m*c*ΔT
⇒ with Q = the heat in Joules = TO BE DETERMINED
⇒ with m = the mass of the solution = 304.88 grams
⇒ with c = the specific heat of the solution = 4.18 J/g°C
⇒ with ΔT = the change in temperature = 6.9 °C
Q = 304.88 g * 4.18 J/g°c * 6.9 °C
Q = 8793.3 J = 8.8 kJ
Q = 8.8 kJ
