according to newton's first law of motion, what does it take to move an object at rest?

a smooth surface and a net force of 100 n

an unbalanced force

a change in gravity

a force equal to the force keeping the object at rest, but in the opposite direction

An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. In the absence of any forces, no force is required to keep an object moving.

So the answer is either (a) or (d)

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
