No, a millilitre is a measure, so it is neither scalar nor vector. It is a measure of volume and that is a scalar.
Time is scalar
In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.
"Time" is a scalar."Hangtime" is a myth.
A scalar times a vector is a vector.
A scalar multiplied by a vector involves multiplying each component of the vector by the scalar value. This operation scales the vector's magnitude while retaining its direction if the scalar is positive, or reversing its direction if the scalar is negative. The result is a new vector that has the same direction as the original (or the opposite direction if the scalar is negative) but a different magnitude.
No, mass is not a scalar quantity. It is a scalar quantity. Scalars have only magnitude and no direction.
Time is typically considered a scalar. However, if you are considering yesterday as a negative time from today, then it looks as a vector. -10 hours has the flavor of a vector. This is a one dimensional vector, (+) is forward and (-) is backwards. Others have considered time as a 2 dimensional thing. I am not familiar with those workings (yet).

No, mass and energy are not scalars. Mass is a scalar quantity while energy is a scalar quantity.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Temperature is a scalar quantity. It has magnitude but not direction.
acceleration is never a scalar...it describes in what direction is the motion of an object changing, so it can't be a scalar...
