Answer:

To find a base by its formula, does it end in COO-

A base never ens with COOH

Explanation:

According to Bronsted Acid - Base theory : When an acid and base reacts with each other , the acid form its conjugate base and base will form its conjugate acid because of exchange of proton .

If HA = acid and B = base react each other then they generate their conjugate Base (A-) and acid (HB+) respectively .

The equation is represented as :

HA+B\rightleftharpoons A^{-}+HB^{+}

Here A- is conjugate base of HA acid

HB+ is conjugate acid of base B

COOH group is the carboxylic acid group = acid

Suppose A carboxylic acid RCOOH is added in water(H2O)

RCOOH + H_{2}O\rightleftharpoons RCOO^{-}+H^{+}

Here

RCOOH = Acid and its conjugate -base is RCOO-

Hence A Base end with formula COO-

COOH is always acid

Answer:

Percent relative error = 0.191%

Explanation:

Relative error is a measure of accuracy (How closeness is the measure to the accepted value) for a determined data. The formula is:

Percent relative error = |Experimental - Accepted| / Accepted * 100

<em>Where experimental is the average of the data:</em>

(40.220g/mol + 40.654g/mol + 40.314g/mol + 40.165g/mol + 40.554g/mol) / 5 =

40.381g/mol

Replacing using accepted value = 40.304g/mol:

|40.381g/mol - 40.304g/mol| / 40.304g/mol * 100

<h3>Percent relative error = 0.191%</h3>

How does water’s ability to form hydrogen bonds explain why ice is less dense than liquid water?
Karolina [17]

Answer:

As water freezes, a crystalline structure preserved by hydrogen bonding is formed by water molecules. Less dense than liquid water is solid water, or ice. Ice is less dense than water since molecules are pulled farther apart by the direction of hydrogen bonds, which decreases density.

mart [117]

It takes so much heat to melt ice or evaporate water because extra energy is required to break the hydrogen bonds between water molecules.

<h3>Hydrogen bond</h3>

Hydrogen bonding is an electrostatic force of attraction between a hydrogen atom found between a pair of other atoms having a high affinity for electrons.

Hydrogen bonds cause water to be exceptionally attracted to each other creating cohesion.

It takes so much heat to melt ice or evaporate water because extra energy is required to break the hydrogen bonds between water molecules.

Which of the following is an
eimsori [14]

Answer:

2 and 4

Explanation:

The rest of the changes are chemical. 1 has a chemical reaction happen which makes light sticks glow. 3 is because browning the meat actually causes some new compounds to form and cause caramelization.

For 2, the oxygen is simply heating up and expanding which pops the balloon. 4 is just a phase change of water vapor to liquid water.
