Explanation Given Specific heat of the solution is 4.18 J/g-°C . Initial temperature of the solution is 23.0 °C . Final temperature of the solution is 34.1 °C . Volume of solution is 100 mL . Mass of magnesium is 0.243 g . Change in temperature is calculated as, Δ T = T f − T i Where, Δ T is the change in temperature. T f is the final temperature of the solution. T i is the initial temperature of the solution. Substitute the values of T f and T i in the above formula. Δ T = 34.1 °C − 23.0 °C = 11.1 °C As the given reaction happens in aqueous medium, density of solution is considered to be 1 g/mL . Mass of the solution is calculated as, m = d × V Where, m is the mass of solution. d is the density of solution. V is the volume of solution. Substitute the values of d and V in the above formula. m = 1 g/mL × 100 mL = 100 g The heat absorbed or released by the given reaction is calculated as, q rxn = − C S × m × Δ T Where, q rxn is the amount of heat absorbed or released by the reaction. C s is the specific heat. m is the mass of solution. Δ T is the change in temperature of the solution. Substitute the values of C s , m and Δ T in the above equation. q rxn = − 4

Ideal and Real Gases

Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,

Gas Laws

Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries we…

Gaseous State

It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed fo…
