<h2><u>Given</u> :-</h2>

State and explain the three basic properties of element.

<h2><u>Answer</u> :-</h2>

Some properties of an element can be observed only in a collection of atoms or molecules of the element. These properties include color, density, melting point, boiling point, and thermal and electrical conductivity.

Answer: Some are solid, some are gaseous, a few are liquid. Some are metallic: they have a peculiar lustre; some are coloured (like sulfur) or colourless. Some have a low density; some have a high density. Some are malleable and ductile; some are brittle. Some conduct electricity and heat well; some don’t.

Many metals tend to have structural uses. Nonmetallic elements less so.

Metals tend to have crystal forms featuring close-packed centro-symmetrical structures. Nonmetallic elements tend to have crystal structures featuring more open and directionally packed structures.

Some are especially toxic; some are essential to life; some are both depending on exposure level.

Most are stable; some are less so.

Some elements are highly reactive; some are almost inert (helium, neon, and argon may be completely inert in ambient conditions).

Many metals have basic oxides; quite a few oxides of nonmetallic elements form acids when they are dissolved in water. Some elements can go both ways.

There are many generalisations you can make about metallic and nonmetallic elements, and quite a few exceptions at the margins.

5.25 x 10^32 atoms of K to grams
NNADVOKAT [17]

Answer:

3.40x10¹⁰ grams

Explanation:

First we<u> convert 5.25x10³² atoms to moles</u>, using <em>Avogadro's number</em>:

5.25x10³² atoms ÷ 6.023x10²³ atoms/mol = 88.72x10⁸ mol

Then we<u> convert K moles to grams</u>, using its <em>molar mass</em>:

88.72x10⁸ mol * 39 g/mol = 3.40x10¹⁰ g

So 5.25x10³² atoms of K would weigh 3.40x10¹⁰ grams.

What is 30-9x2*2-21-4+4
IgorC [24]
Answer:
9 (1-2x²)

Explanation:
The given expression is:
30 - 9x²*2 - 21 - 4 + 4
The first step is to compute the multiplication. This will give:
30 - 18x² - 21 - 4 + 4
Then, we will add like terms as follows:
(30-21-4+4) - 18x²
= 9 - 18x²
Finally, we can take the 9 as a common factor from both terms, this will give:
9 (1-2x²)

Hope this helps :)

Standard reduction potentials for zinc(II) and copper(II) The standard reduction potential for a substance indicates how readily
givi [52]

The question is incomplete, the complete question is:

Standard reduction potentials for zinc(II) and copper(II)

The standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. The more positive the reduction potential, the more easily the substance gains electrons. Consider the following:

Zn2+(aq)+2e−→Zn(s),Cu2+(aq)+2e−→Cu(s), E∘red=−0.763 V E∘red=+0.337 V

Part B

What is the standard potential, E∘cell, for this galvanic cell? Use the given standard reduction potentials in your calculation as appropriate.

Express your answer to three decimal places and include the appropriate units.

Answer:

1.100 V

Explanation:

E∘cell= E∘cathode - E∘anode

E∘cathode= +0.337 V

E∘anode= −0.763 V

E∘cell= 0.337-(-0.763)

E∘cell= 1.1V

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
pishuonlain [190]

Answer:

V=25.133 cm^3

(Is 4 the diameter you were given? To get one of those answers, I think you May have put the wrong diameter)

Explanation:

Radius is diameter/2

R=4/2

R=2

Volume of a sphere=4/3πr3

V=4/3π(2)3

V=25.133 cm^3
