Answer:
CaCO3: 1 calcium 1 carbon 3 oxygen
CaO: 1 calcium 1 oxygen
CO2: 1 carbon 2 oxygen
Answer is: tomatoes is thousand (1000) times more acidic than water.
pH(tomato) = 4.00.
pH(water) = 7.00.
pH = -log[H⁺<span>].
</span>[H⁺] = 10∧(-pH); concentration of hydrogen ions.
[H⁺] = 10⁻⁴ M = 0.0001 M; tomato.
[H⁺] = 10⁻⁷ M = 0.0000001 M; water.
[H⁺](tomato) /[H⁺](water) = 0.0001 M ÷ 0.0000001 M.
[H⁺](tomato) /[H⁺](water) = 1000.
For this problem, we use Graham's Effusion Law to find out the rate of effusion of chlorine gas. The formula is as follows:
R₁/R₂ = √(M₂/M₁)
Let 1 be N₂ while 2 be Cl₂
255/R₂ = √(28/70.8)
Solving for R₂,
R₂ = 405.5 s
<em>Thus, it would take 405.5 s to effuse chlorine gas.</em>
Explanation:
It is given that for acetic acid is . And, its value will be calculated as follows.
=
= 4.74
And, according to the Henderson-Hasselbalch equation,
pH =
(1). When [Acetic acid] is ten times greater than [acetate]
This means that
So, pH =
=
= 3.74
(2). When [Acetate] ten times greater than [Acetic acid]
This means that =
pH =
= 5.74
(3). When [acetate] = [acetic acid]
This means that = 1
pH =
= 4.74
