it is defined as the ratio of moles of one substance to the moles of another substance in a balanced equation. To determine the mole ratio between two substances, all you need to do is look at the balanced equation for the coefficients in front of the substances you are interested in.
Compounds often differ from elements.
5.0x10^1 kg is the correct answer
Explanation: When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object. ... Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
Change in energy is E=hc/wavelength of emitted photon
