Look at the products of the chemical reaction to determine if the reactant added to water caused an acid reaction, a base reacti

on, or a neutralization reaction.
Acid


Neutralization


Base

1.
2HF + 2CaOH -> 2H2O + 2NaF

2.
3HI + 2H2O -> 2H3O+ + 3I- + H+

3.
2CH3COO- + H2O -> CH3COO- + OH- + CH3COOH

1. The reaction is a neutralization reaction

2. The reactant added to the water causes an acid reaction

3. The reactant added to the water causes a base reaction

4. The molarity of the solution is 0.025 M

<h3>What is a neutralization reaction? </h3>

This is a reaction involving an acid and a base which result in the formation of salt and water only

HF + NaOH –> H₂O + NaF

The reaction above indicates neutralization since the reaction produces water (H₂O) and salt (NaF) only

<h3>What is an acid? </h3>

An acid is a substance which dissolves in water to produce hydronium ion H₃O⁺

3HI + 2H₂O —> 2H₃O⁺ + 3I¯ + H⁺

The reaction above is an acid reaction since it produces H₃O⁺

<h3>What is a base? </h3>

A base is a substance which dissolves in water to produce hydroxide ion OH¯

2CH₃COO¯ + H₂O —> CH₃COO¯ + OH¯ + CH₃COOH

The reaction above is a base reaction since OH¯ is produced.

<h3>How to determine the molarity </h3>
  • Mole = 0.05 mole
  • Volume = 2 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 0.05 / 2

Molarity = 0.025 M

The hydrogen bonding in water creates ________, a cohesive force that enables one to slightly overfill a glass with water or all
ziro4ka [17]

Answer: -

Surface Tension

Explanation: -

Surface tension is cohesive force created as a result of hydrogen bonding, that enables a liquid drop to have a minimum surface area.

Due to it being cohesive, the water top surface is concave in nature, allowing us to hence slightly overfill a glass with water.

Due to surface tension, the surface of water behaves like a stretched membrane, allowing dense objects like a length wise steel needle to float on water.

Thus, the hydrogen bonding in water creates __surface tension__, a cohesive force that enables one to slightly overfill a glass with water or allows denser objects, such as a lengthwise steel needle, to float on water

Calculate the solubility of carbon dioxide in water at an atmospheric pressure of 0.400 atm (a typical value at high altitude).
likoan [24]

Answer:

1.40*10⁻² M

Explanation:

We have the solubility formula

Solubility,

S = KH*P  

where

KH = measure of hardness of water / carbonate hardness = 3.50*10⁻² mol/L.atm

P = atmospheric pressure = 0.400 atm

Hence, we have

S = KH*P

= (3.50*10⁻² mol/L.atm)*(0.400 atm)

= 1.40*10⁻² mol/L

But 1 mol/L = 1 M,

Hence, the answer (1.40*10⁻² mol/L ) is equivalent to

= 1.40*10⁻² M

An endergonic reaction with a Δh and Δs can be changed into an exergonic reaction.
zheka24 [161]

Full question:

This question is incomplete, here it is completed:

An endergonic reaction with a ______ ∆H and a ______ ∆S can be changed into an exergonic reaction by decreasing the temperature.

Option A: negative, positive

Option B: negative, negative

Option C: positive, positive

Option D: positive, negative

Answer:

Option B: negative, negative

Explanation:

The change in free energy (ΔG) of a system for a constant-temperature process is

ΔG = ΔH - TΔS

free energy is the energy available to do work. Thus, if a particular reaction is accompanied by a release of usable energy (that is, <u>ΔG is negative</u><u>), it is said to be</u><u> exergonic</u>. On the other hand, if a reaction consumes energy (that is, <u>ΔG is positive</u><u>), it is said to be </u><u>endergonic</u>.

Looking at the equation, we can see that if ΔH is negative and ΔS is negative, then ΔG will be negative only when TΔS  is smaller in magnitude than ΔH. This condition is met when T is small.

ΔG = ΔH - TΔS

           -        -

This means that the reaction proceeds spontaneously at low temperatures. At high temperatures, the reverse reaction becomes spontaneous. An example of that would be the following reaction:

NH₃(g) + HCl(g) → NH₄Cl(s)
