Answer:
The heat of reaction is basically the energy that is being released and or absorbed when chemicals are transformed in a type of chemical reaction. However, the heat of reaction or also called reaction enthalpy is mostly or typically expressed as a molar enthalpy in kJ/mol and or as just a specific enthalpy in kJ/kg or kJ/L.
chemical reactions can release heat (a)
Answer:
The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.
Answer:
Acceleration is zero.
Explanation:
The slope of a position time graph gives the velocity of the body.
If the slope is constant means the velocity is constant.
Now, acceleration is the measure of the change in velocity of a body over a given time interval.
So, the acceleration of a body is directly proportional to the change in velocity of the body.
If there is no change in velocity, this means that the acceleration of the body is zero.
Here, the slope is a constant implying that the velocity is a constant. So, there is no change in velocity. This implies that the acceleration is zero for the body in the given time interval.
Thus, if a position time graph has a constant slope, one can infer that the acceleration is zero.
