Question

Calculate the volume, mass and number of molecules of hydrogen liberated when

230 g of sodium reacts with excess of water at STP. (atomic masses of Na = 23 U,

O = 16 U, and H = 1U)​

Answer 1

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
