How does distillation remove hardness from water​

Answers

Answer:

Distillation can be used to soften water as the water evaporates as it is heated and the ions are left behind.

Hope that helps. x

Answer: Distillation can be used to separate and collect a liquid from a solution. Distillation can also be used to soften water as the water evaporates as it is heated and the ions are left behind. Hard water can be softened by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.

Which part of atomic structure is responsible for the reactivity of atoms?

Answers

the number of electrons in the outermost shell deduces it’s reactivity

The electrons present in the valence shell of an atom are responsible for the reactivity of atoms.

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

which we can overcome this global issue in less than 250 words.

Answers

An alternative method by which we can overcome this global issue is by harnessing Solar energy.

Discussion:

Fossil fuels cause environmental pollution. This is because they are organic compounds and on combustion, they release air pollutants such as, Carbon monoxide.

As a panacea, the use of solar panels for harnessing Solar energy in a bid to replace energy from fossil fuels will prove to be am effective method by which we can overcome the global issue of pollution caused by burning of fossil fuels.

1. One atom contains 29 protons and 34 neutrons. Another atom of the same element has a mass number of 65. How many protons and neutrons does this unknown atom have?

A. 28 protons, 37 neutrons
b. 29 protons, 36 neutrons
C. 29 protons, 35 neutrons
D. 31 protons, 34 neutrons

Answers

Answer:

b

Explanation:

because its the atom of the same element, the no of protons doesn't change but the mass number changes so we can find the mass number by:

(mass number = atomic no/no of protons + no of neutrons)

here;

mass number given = 65

and we know, no of protons = 29

let no of neutrons = x

hence,

65 = 29 + x

x= 65 – 29

x= 36

hence your answer is b

The Gravitational potential energy of

an object at a point above the ground

A force is required to do this. the

minimum force required to raise the

The object gains energy equal to the

The relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].

What is weight of an object?

The weight of an object is determined as the product of the object's mass and acceleration due to gravity.

F = mg

The gravitational force on objects in the universe

The gravitational force between two objects in the universe is directly proportional to the product of mass of the objects and inversely proportional to the square of the distance between the objects.

[tex]F = \frac{GmM}{R^2} [/tex]

[tex]mg = \frac{GmM}{R^2} \\\\ g = \frac{GM}{R^2} [/tex]

M is the mass of the earth

R is the radius of the earth

6.5 moles of AgCl can be formed from 6.5 moles of Ag.

STOICHIOMETRY:

According to this question, silver reacts with hydrochloric acid to form silver chloride and hydrogen gas as follows:

2Ag + 2HCl → 2AgCl + H2

Based on this balanced equation, 2 moles of silver (Ag) produces 2 moles of silver chloride (AgCl).

This means that 6.5 moles of Ag will produce (6.5 × 2)/2 = 6.5 moles of AgCl.
