Gen Chem SI 6: We're Still On Concepts!

Type of acid (important at cochella)

100

What is the difference between a bronsted lowry acid and an arrhenius acid.

BL = donates a proton (acid) or accepts a proton (base)

Arrhenius = creates H+ in soln (acid) or creates OH- in soln (base)

200

Is NH₃ a bronsted lowry base, a arrhenius base, or both.

Bronsted lowry base! (it can accept an H ion but cannot increase the amount of OH in solution)

300

Is HF in solution a arrhenius acid, or bronsted lowry acid, or both.

Both! HF increases the H ions in solutions (arrhenius) but also donates an H (bronsted)

400

Sort the following compounds into BL acids, BL bases, or BL+A acids, BL+A bases.

HF, HNO₃, Ca(OH)₂, NH₄⁺, H₂SO₄, NH₃

BL acids

NH₄⁺

Both types of acid

HF, HNO₃⁺, H₂SO₄

BL base

NH₃

Both types of base

Ca(OH)₂

500

What type of Acid is BF₃

Lewis acid (can accept a pair of electrons)

Base can donate a pair of electrons

200

Give me the molecular equation for the reaction of sodium hydroxide with hydrochloric acid to form water and sodium chloride.

NaOH (aq)+HCl (aq)→NaCl (aq)+H₂O (l)

300

Ba₂⁺(aq)+2NO₃^-(aq)+2Na⁺(aq)+SO₄²

(aq)→BaSO₄(s)+2Na⁺(aq)+2NO₃^-(aq)

Given this complete ionic equation, give me the molecular equation.

Ba(NO₃)₂(aq)+Na₂SO₄(aq)→BaSO₄(s)+2NaNO₃(aq)

400

HCl (aq)+NaOH (aq)→NaCl (aq)+H₂O (l)

Give me the COMPLETE ionic equation for this reaction.

H+(aq)+Cl−(aq)+Na+(aq)+OH−(aq)→Na+(aq)+Cl−(aq)+H₂O (l)

500

Free space!

Everyone gets 500 points! (So zero!)

Strong Vs Weak

100

Ca(OH)₂

_{Strong or week}

Strong

200

HCl

Strong or week

Strong

300

NH₃

Weak base!

400

Al(OH)₃

weak base, despite hydroxides best effort. It doesnt dissociate completely

500

What acid + base combo do you need for a neutralization reaction?

Strong/weak, weak/weak, strong/strong, weak/strong.

HAHAHAHAHAH!!!! it does not matter! (how could you have known this?! I am cruel i am sorry D:)

What does it effect though?

The third acid category (Misc. acid questions)

100

What is the reaction called when an acid and base react with eachother to form a salt and water.

Neutralization

200

Which of the following are diprotic?

• Hydrochloric acid HCl
• Sulfuric acid H₂SO₄
• Nitric acid HNO₃
• Carbonic acid H₂CO₃
• Acetic acid CH₃COOH

Sulfuric and Carbonic

300

H2SO4(aq)+2NaOH(aq)→Na2SO4(aq)+2H2O (l)

Lable each molecule in this equation with one of the following

Salt

Base

Acid

Water

Acid, base, salt, water

400

What is the difference between a weak acid and a strong acid?

One completely dissociates in water while the other only partially does.

500

How many acidic hydrogens are in 

Acetic acid - CH₃COOH

1 crazy acidic hydrogen

Random world trivia. (slightly chemistry related)

100

What is the 5th planet from the sun?

What chemical state does it exist in?

Jupiter, which is mostly a gas!

200

Give me the common names, and chemical symbols of the two molecules that combine to form the very toxic and chloramine gas?

Hint, one of them is Sodium Hypochlorite.

Ammonia and bleach.

NH₃ NaClO

Why is this toxic?

300

What is the name of the only body of water on the planet where humans float instead of sink.

Why do we float on this body of water?

Dead sea, because of the salt content.

400

What type of reaction was in the event that started WWI

Acid base, Combustion, Redox, Neutralization, Double replacement.

Combustion! (the shooting of franz ferdinand)

500

What U.S city was once called New Amsterdam

What two elements does the new city have in its abbreviation.

New York, NY, Nitrogen Yttrium.
