Elena held a rock weighing 1 N in her hand. The rock has no velocity. KE________?
1 answer:
KE = 0
<h3>Further explanation </h3>Energy is the ability to do work
Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:
So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy
The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy
But this stone can have <em>potential energy that is gained due to its height</em>

Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of
Standard free energy change of the reaction () is given as:
, where T represents temperature in kelvin scale
So,
So, for the reaction of 1.57 moles of ,
As, is negative therefore reaction is product favored under standard condition.
