Answer:
newton's 3 laws state:
- an object in motion stays in motion (unless an external force acts on it)
- every action has an opposite but equal reaction
- force= mass x acceleration
Explanation:
Given
The enthalpy of formation of RbF (s) is –557.7kJ/mol
The standard enthalpy of formation of RbF (aq, 1 m) is –583.8 kJ/mol
The enthalpy of solution of RbF = Enthalpy of RbF (aq) - Enthalpy of formation of RbF (s)
= -583.8 - (-557.7) kJ/mol
= -26.1 kJ/mol
The enthalpy is negative which means that the temperature will rise when RbF is dissolved.
Answer:
Age of the ancient wood object is 11460 years.
Explanation:
We know that half-life for carbon-14 is 5730 years. That means the activity of the sample will decrease to half every 5730 years.
Now we construct the following table:
activity (counts/min) age of the wooden object
40 0
20 5730
10 11460
