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:
A tendon is a fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Explanation:
Answer:
Explanation:
carbon in group 4A needs 4 more electrons to be stable
hydrogen in group 1A has one electron needs 1 more t o be stale
oxygen in group 6A has 6 and needs 2 more to be stable
They all obtain this by sharing electrons 8 around C &O, 2 around H
H : C: H
