2.167*10^22 atoms of hydrogen
Answer:
The balanced chemical equation:
Heat of combustion per gram of phenol is 32.454 kJ/g
Heat of combustion per gram of phenol is 3,050 kJ/mol
Explanation:
Heat capacity of calorimeter = C = 11.66 kJ/°C
Initial temperature of the calorimeter = 
Final temperature of the calorimeter = 
Heat absorbed by calorimeter = Q
Heat released during reaction = Q'
Q' = -Q ( law of conservation of energy)
Energy released on combustion of 1.800 grams of phenol = Q' = -(58.4166 kJ)
Heat of combustion per gram of phenol:
Molar mass of phenol = 94 g/mol
Heat of combustion per gram of phenol:
The scatter plot that shows a positive correlation between force and acceleration.
<h3>What is the relationship between acceleration of an object and the applied force?</h3>
The acceleration of an object is the change in velocity with time.
- Acceleration = change in velocity/time
Force is defined as an agent which causes a change in the motion or state of rest of a body.
According to Newton's law of motion, the rate of change of velocity of an object is directly proportional to the applied force and takes place in the direction of the applied force.
Force and acceleration have a positive correlation.
Therefore, the scatter plot which will most closely match the measurements that the students will obtain is that which shows a positive correlation between force and acceleration.
In conclusion, acceleration of a object is proportional to the applied force.
