Is this equation balanced and in the lowest form? 4nh3 → 2n2 + 6h2 yes, because there are equal amounts of atoms of each element on both sides. no, because the coefficients could be reduced to 2,1, and 3. yes, because the coefficients are in their lowest whole number ratio. no, because the coefficients could be reduced to 2, 2, and 4.

The given equation is not balanced in its lowest form because the coefficients could be reduced to 2, 1 and 3.

Explanation: We are given a equation but it is not balanced in its lowest form, so to reduce it into its lowest form, we divide the whole equation by 2.

The equation becomes:

The coefficients for the equation are 2, 1 and 3.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
