D he predicted 3(?) new element that we're later discovered
Answer:
A reduction potential measures the tendency of a molecule to be reduced by taking up new electrons. ... Standard reduction potentials can be useful in determining the directionality of a reaction. The reduction potential of a given species can be considered to be the negative of the oxidation potential.
Explanation:
Answer:
ΔH = -110.5kJ
Explanation:
It is possible to obtain enthalpy of combustion of a particular reaction by the algebraic sum of similar reactions (Hess's law). Using:
1. C(s) + O₂(g) → CO₂(g) ΔH₁ = -393.5kJ
2. CO(g) + 1/2O₂(g) → CO₂(g) ΔH₂ = -283.0kJ
The sum of 1 -2 gives:
C(s) + <u>O₂(g)</u> + <u>CO₂(g)</u> → <u>CO₂(g)</u> + CO(g) + <u>1/2O₂(g)</u>
C(s) + 1/2O₂(g) → CO(g) ΔH = -393.5kJ - (-283.0kJ) =
<h3>ΔH = -110.5kJ</h3>

Answer:

Explanation:
Here, we want to select a disadvantage of the power sources
The two listed are examples of renewable power sources with no level of pollution
However, in the case of wind, a wind turbine is needed and could only work in places where the wind is prevalent enough throughout the year. Likewise, hydroelectric power, can only work where we have a flowing water source
Thus, there is a bane of geographic and climatic restrictions serving as a disadvantage
Answer: No reaction occurs
Explanation:.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:

The complete ionic equation is;

The ions which are present on both the sides of the equation are are not involved in net ionic equation.
Hence, there is no net reaction.
