Answer:
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by calorimeter = Joules
C = heat capacity of calorimeter = ?
Initial temperature of the calorimeter = = 22.37°C
Final temperature of the calorimeter = = 24.68°C
Change in temperature ,
Putting in the values, we get:
The heat capacity of the calorimeter is
Answer: a. Have an overall neutral charge
b. Have electrons that are not equally shared
d. Have slight positive and negative ends
Explanation:
Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example:
The more electronegative element i.e. chlorine acquires a partial negative charge as it withdraws the electron density towards itself. Thus hydrogen acquires a partial positive charge. The opposite charges cancel each other and thus overall it is electrically neutral.
