If a balloon containing 3000 L of gas at 39°C and 99 kPa rises to an altitude where the pressure is 45.5 kPa and the temperature

ludmilkaskok [199]

$\tt =3000~L\times \dfrac{289}{312}\times \dfrac{99}{45.5}$

<h3>Further explanation</h3>

Given

3000 L of gas at 39°C and 99 kPa to 45.5 kPa and 16°C,

Required

the new volume

Solution

Combined with Boyle's law and Gay Lussac's law

$\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}$

T₁ = 39 + 273 = 312

T₂ = 16 + 273 = 289

Input the value :

V₂ = (P₁V₁.T₂)/(P₂.T₁)

V₂ = (99 x 3000 x 289)/(45.5 x 312)

or we can write it as:

V₂ = 3000 L x (289/312) x (99/45.5)

28 Which compound yields H + ions as the only positive ions in an aqueous solution?

MrMuchimi

Answer: (4) $CH_3COOH$

Explanation:-

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydronium ions $(H_3O^+)$ in water.

1. $KOH$ is a strong electrolyte and thus dissociate in water. $KOH\rightarrow K^++OH^-$

2. $CH_3OH$ is a non electrolyte and thus do no dissociate in water.

$CH_3COOH\rightarrow no reaction$

3. $NaOH$ is a strong electrolyte and thus dissociate in water.

$NaOH\rightarrow Na^++OH^-$

4. $CH_3COOH$ is a weak electrolyte and thus partially dissociate in water.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$
