Answer : The correct option is, (4) OH^-(aq).

Explanation :

According to the Arrhenius theory, an acid is a substance that ionizes in water to gives H^+ ions (hydronium ions or hydrogen ions) and a base is a substance which ionizes in water to gives OH^- ions (hydroxide ions).

As we know that when the potassium hydroxide (KOH) dissolves in water or ionizes in water to gives OH^- ions (hydroxide ions) and K^+ ions (potassium ion). That means OH^- ion is a negative ion in aqueous solution and K^+ ions is a positive ion in aqueous solution.

Hence, the correct option is, (4) OH^-(aq).

A 4.24 kg marble slab has the volume of 1564 cm3 What is the density in g/cm3
miskamm [114]

Answer:

The answer is

<h2>2.71 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

volume of marble = 1564 cm³

1 kg = 1000 g

4.24 kg = 4240 g

mass = 4240 g

The density is

density =  \frac{4240}{1564}   \\  = 2.710997442...

We have the final answer as

<h3>2.71 g/cm³</h3>

Hope this helps you
