Answer:
four holes
Explanation:
A ball and stick model is a representation of a molecule that can show the number of bonds and sometimes, the stereochemistry of the molecule under study.
The number of holes on present in the ball and stick model for any atom corresponds to the number of bonds that particular atom can form without violating the octet rule.
Carbon is usually tetravalent, it forms four bonds to other atoms. Hence we expect carbon to have four holes.
Answer:
A 1.0 g sample of propane, C3H8, was burned in the calorimeter.
The temperature rose from 28.5 0C to 32.0 0C and the heat of combustion 10.5 kJ/g.
Calculate the heat capacity of the calorimeter apparatus in kJ/0C
Explanation:
Given,
The heat of combustion = 10.5kJ/g.
Substitute these values in the above formula to get the value of heat capacity of the calorimeter.
Answer:
The heat capacity of the calorimeter is
