A vector
Heat capacity is a scalar quantity, as it does not have a direction associated with it. It is a measure of the amount of heat energy required to raise the temperature of a substance by a certain amount.
A scalar times a vector is a vector.

Scalar
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the scalar.
An earthquake is neither a scalar nor a vector. It is an event.

Yes, you can multiply a vector by a scalar. The scalar will multiply each component of the vector by the same value, resulting in a new vector with each component scaled by that value.
