Explanation:

If soil consists of more acidic nature then, it does not allow plant growth.

In that situation, treat the soil with (anti-acid which is nothing but) base.

When an acid reacts with a base, a neutralization reaction takes place and salt and water are formed in this reaction.

The equation is shown below:

acid+base-> salt +water

For example, if the soil has more sulphuric acid traces then, it should be treated with lime.

$H_2SO_4(aq)+Ca(OH)_2(aq)->CaSO_4(aq)+2H_2O(l)$

Calculate the volume of a sample of aluminum that has a mass of 3.057 kg. The density of aluminum is 2.70 g/cm3 (taking into con

Misha Larkins [42]

Answer:

v = 1130 cm³

Explanation:

Given data:

Volume of sample = ?

Mass of Al sample = 3.057 Kg (3.057 Kg× 1000g/1 Kg = 3057g)

Density of Al sample = 2.70 g/cm³

Solution:

Formula:

d = m/v

d = density

m = mass

v= volume

by putting values

2.70 g/cm³ = 3057g /v

v = 3057g /2.70 g/cm³

v = 1130 cm³

Why are the noble gases (group 18) inert?

dalvyx [7]

The noble gases are relatively unreactive because they have a stable octet of valence electrons.

Thus, they do not tend to undergo reactions in which they will gain or lose valence electrons,

However, only He, Ne, and Ar are inert. Kr and Xe combine with other highly reactive elements to form stable compounds.
