How does the potential energy of a double bond (like oxygen-oxygen) compare to a weak interaction or single bond (like argon-oxy

astraxan [27]

Answer:

Potential energy in a double bond is going to be higher than the potential energy of a single bond due to the force needed to break a double bond as opposed to a single. Single bond is weaker, which means less energy is needed to break it. Double bonds are stronger, requiring more energy to break the bond.

Help pls thnk you!!!!

Degger [83]

The amine here is the easiest to spot since there’s only one structure that has a nitrogen atom, which would be the first (the first structure is a primary amine).

The distinguishing functional group of an alcohol is the hydroxy group (—OH). Both the second and third structures have an —OH group, but the —OH in the third structure is part of a carboxyl group (—COOH or —C(=O)OH). A carboxyl group takes priority over hydroxy group. Thus, the second structure would be an alcohol and the third structure would be a carboxylic acid.

That leaves us with the fourth structure, a hydrocarbon with a halogen substitutent, or, aptly named, a halocarbon.

Number 51 is 0.00150 ml to l

xenn [34]

Answer:

The answer to your question is

51.- 1.59 x 10⁻⁶

53.- NaHCO₃ + HCl ⇒ H₂O + CO₂ + NaCl

Explanation:

51.- Convert 0.00159 ml to liters

Use a rule of three

1000 ml -------------- 1 l

0.00159 ml --------- x

x = (0.00159 x 1) / 1000

x = 0.00000159 l = 1.59 x 10⁻⁶ l

53.- Sodium hydrogen carbonate (NaHCO₃) reacts with hydrochloric acid to produce salt, water and carbon dioxide.

Sodium hydrogen carbonate = NaHCO₃

Hydrochloric acid = HCl

Reaction

NaHCO₃ + HCl ⇒ H₂O + CO₂ + NaCl

water = H₂O

carbon dioxide = CO₂

salt = NaCl

An ideal gas does not exist.

ozzi

Answer:

an ideal gas does not exist except as a conceptual notion, an ideal. Physicists and chemists idealized the behaviour of real gases so that they could explain these phenomena. Under conditions of low pressure and high temperature, all gases behave like real gases, even gases such as UF6 .
