Answer:
b) At equilibrium, equal amounts of products and reactants are present.
Explanation:
At equilibrium , the ratio of product of concentration of products and product of concentration of reactants is constant .
A + B ⇄ C + D
[C] [ D] / [ A ] [ B ] = Constant
So, the statement ( b ) is false .
All other statements are true .
<span>No, xenon will not react on Nitrogen because xenon
only reacts with oxygen and fluorine. Xenon only reacts with the 2 elements
because these 2 elements contain a strong electronegative element which is high
in energy barrier that can move the electrons inside xenon elements. Xenon is an element with a symbol of Xe, it
is odorless and colorless gas. Common uses of xenon are flash lamps and arc
lamps. Xenon is a luminous element, it glows when placed near to high voltage
electric field.

Answer:
D. mass has a greater effect than height on gravitational potential energy
Explanation:
The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of gravitational potential energy the object loses as it falls. ... This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.More massive objects have greater gravitational potential energy.
