What is the ratio of sodium ions to bromide ions in neutral sodium bromide?

frosja888 [35]

The ratio of sodium ions to bromide ions in neutral sodium bromide would be 1 is to 1. The molecular formula of sodium bromide would be NaBr where in every ion of Na there is one corresponding ion of bromide present. Hope this helps. Have a nice day.

Draw the Lewis structures for CH3OH, CH2O and HCOOH. Indicate the hybrid orbital used in the sigma bonds for each of the carbon

sdas [7]

Answer:

See figure 1

Explanation:

For this question, we have to remember that in the lewis structures all atoms must have 8 electrons. And each atom would have a different value of valence electrons:

Carbon => 4

Oxygen=> 6

Hydrogen=> 1

Additionally, for the hybridizations we have to remember that:

$Sp^3$ => 4 single bonds

$Sp^2$ => 1 double bond

$Sp^1$ => 1 double bond

With this in mind, the formaldehyde and formic acid would have $Sp^2$ carbons and the ethanol an $Sp^3$ carbon.

Finally, for the oxidation state. We have to remember that if we have more bonds with oxygen, we will have more oxidation. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).

See figure 1

I hope it helps!

During the lab, you measured the pH of mixtures containing strong acid and strong base. Write net Brønsted equations that show t

jasenka [17]

Answer:

ClO⁻ + HC₂H₃O₂ ⇄ HClO + C₂H₃O₂⁻

Explanation:

Sodium hypochlorite is a strong electrolyte that ionizes in sodium cation and hypochlorite anion.

NaClO(aq) ⇒ Na⁺(aq) + ClO⁻(aq)

ClO⁻ is a base that reacts with acetic acid (HC₂H₃O₂) from vinegar (neutralization reaction).

ClO⁻ + HC₂H₃O₂ ⇄ HClO + C₂H₃O₂⁻
