What is the difference between a strong and weak acid?

Mademuasel [1]

Answer:

The strong acids are fully ionized in aqueous solution, and they contains higher concentration of hydrogen ions. Strong acids are lower pH in nature. Some examples of strong acids are:

1) Hydrochloric acid.

2) Nitric acid.

3) Sulfuric acid.

The weak acids are not fully ionized, means they are partially ionized in aqueous solution, and they contains lower concentration of hydrogen ions. Weak acids are higher pH in nature than strong acid. Some examples of weak acids are:

1) Ethanoic acid.

2) Acetic acid.

3) Nitrous acid.

The air pressure for a certain tire is 109 kPa. What is this pressure in atmospheres?

Len [333]

1.08 atm is the pressure for a certain tire in atmosphere.

<u>Explanation:</u>

One kilo pascal (1 kPa) corresponds to 1000 pascal. Another common unit used for pressure is atmosphere (symbolised as ‘atm’). 1 atm refers the standard atmospheric pressures and corresponds to 760 mm Hg and 101.3 kPa. Atmospheric pressures are commonly referred as square inches (psi)/ pounds.

$1 \mathrm{atm}=101.3 \mathrm{kPa}=101,325 \mathrm{Pa}=760 \mathrm{mm} \mathrm{Hg}=760 \text { torr }=14.7 \mathrm{lb} / \mathrm{in}^{2}(\mathrm{psi})$

Given:

The air pressure for a certain tire = 109 kPa

We need to find pressure in atmospheres

So, we know,

1 atm = 101.3 kPa

Hence,

$\frac{109 \mathrm{kPa}}{1} \times \frac{1 \mathrm{atm}}{101.3 \mathrm{kPa}}=1.076=1.08 \mathrm{atm}$

1.08 atm is the pressure for a certain tire in atmosphere.

HELP NEED HELP PLEASE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Goshia [24]

Answer: B) 4.2 M

Explanation:

Molarity = moles of solute/litre of solution

1560mL/1000 = 1.56 litres

6.5/1.56 = x/1

x = 4.2

M of solution = 4.2
