Answer: On the basis of electrical conductivity, materials are classified as conductors, semi-conductors and non-conductors. Conductors : Substances through which electricity can easily pass through are known as conductors. ... For example, glass, wood are non-conductors. Wood is used to make tables, desks etc.

Calculate the % composition of the unknown liquid using your most precise result. It is a mixture of ethanol (D[ETOH] = 0.7890 g

Rufina [12.5K]

% composition of ethanol = 34.51%

% composition of water = 65.49%

<h3>What is density?</h3>

A material's density is defined as its mass per unit volume.

Given data:

The density of ethanol = 0.7890 g/mL

The density of water = 0.9982 g/mL

The density of mixture = 0.926 g/mL

Let the % composition of ethanol = x

Let the % composition of water = 100-x

Now density of the mixture

$\frac{Mass}{Volume}$

$Mass = \frac{percent \;of \;ethanol \;X \;density \;of \;ethanol \;+ \\ \;percent \;of \;water X \;density \;of \;water}{100}$

$0.926 = \frac{x X 0.7890 g/mL \;+ (100-x) X 0.9982 g/mL}{100}$

$x= 34.51$ %

Hence,

% composition of ethanol = 34.51%

% composition of water = 65.49%

And even though science has given us the entire physical breakdown, there's never been a successful attempt at bringing a human to life. There's still something missing. Something scientists haven't been able to find in centuries of research. ...and in case you're wondering, all those ingredients can be bought on a child's allowance. humans can be made rather cheap. There's no magic to it.

Pavel [41]

Answer:

<em>Protons: </em>

Positively charged particle

The number of these is the atomic number

All atoms of a given element have the same number of these

<em>Neutrons: </em>

Neutral particles

Isotopes of a given element differ in the number of these

The mass number is the number of these added to the number of protons

Explanation:

Protons (<em>positively charged</em>), neutrons (<em>neutral</em>) and electrons (negatively charged) are smaller than an atom and they are the main subatomic particles. The nucleus of an atom is composed of protons and neutrons, and the electrons are in the periphery at unknown pathways.

The <em>Atomic number</em> (Z) indicates the number of protons ( $P^{+}$ ) in the nucleus. Every atom of an element have the <em>same atomic number</em>, thus the <em>same number of protons</em>.

The <em>mass number </em>(A) is the sum of the <em>number of protons</em> ( $P^{+}$ ) <em>and neutrons</em> (N) that are present in the nucleus: <em>A= Z + N</em>

<em>Isotopes</em> are atoms of the <em>same element </em>which nucleus have the <em>same atomic number</em> (Z), and <em>different mass number (A)</em>, it means the <em>same number of protons</em> ( $P^{+}$ ) and a <em>different number of neutrons</em> (N). For example, the oxygen in its natural state is a mixture of isotopes:

99.8% atoms with A= 16, Z=8, and N=8

0.037% atoms with A=17, Z=8, and N=9

0.204% atoms with A=18, Z=8, and N=10
