Answer:
The first one is balanced. The second one is not.
Explanation:
The first one is balanced because there are the same amount of elements on the reactant side as there are on the product side. The second one is not balanced because there are not the same amount of elements on the reactant side as there are on the product side. Therefore, it is not balanced
More Detailed: first example
Reactant side (left of arrow)
H: 2
C: 1
O: 3
Product side (right of arrow)
H: 2
C: 1
O: 3
More detailed: second example
Reactant side:
Na: 1
O: 1
H: 1
C: 1
Product side:
Na: 2
O: 4
H: 2
C: 1
the variables needed to balance this equation is 2,1, 1, 1.
The answer is True because elements in a compound combine and become an entirely different substance with its own unique properties.
Answer is: temperature must be increased to very high values.
The change in
Gibbs free energy (ΔG), at constant temperature and pressure, is: <span>ΔG=ΔH−TΔS.
ΔH is the change in enthalpy; in this example </span>ΔH>0.<span>.
ΔS is change in entropy; </span>ΔS>0.<span>
T is temperature of the system.
When ΔG is negative, a reaction (occurs without the addition of
external energy) will be spontaneous (exergonic).
TΔS > ΔH.</span>
Answer:
like, plasmas have no fixed shape or volume, and are less dense then solid or liquids but unlike ordinary gases, plasma are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roem freely
