How are elements and compounds different?

Chemistry
2 answers:
Nataliya [291]3 years ago
3 0

Answer:

Elements only contain one type of atoms while compounds contain two or more types of atoms.

Explanation:

An example of an element is sodium --> Na (only Na atoms)

An example of a compound can be water --> H2O (contain H and O atoms)

*But the particles within a compound are all the same.

No. Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.

Given that the density of gold and sand are 19. 3 g/cm^3 and 2. 95 g/cm^3, respectively, and that the density of the mixture is
SOVA2 [1]

The percent by mass of gold in the mixture will be 34.5%.

How to calculate the percentage?

The following information can be deduced based on the information given:

Density of gold = 19.3 g/cm³.

Density of sand = 2.94 g/cm³

Density of mixture = 4.17 g/cm³

It should be noted that when we find the volume fo gold on a 1cm³ sample, then we can be able to find that mass. The volume of gold will be calculated thus:

4.17 = [(19.3x + 2.95(1 - x)]

4.17 = 19.3x + 2.95 - 2.95x

4.17 = 16.35x + 2.95

x = 0.0746cm³

The mass of gold will be:

= 0.0746 × 19.3

= 1.44

The percent by mass of gold in the mixture will be:

= 1.44/4.17 × 100

= 34.5%

In conclusion, the percent by mass of gold in the mixture will be 34.5%.

What is Mass?

Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia, or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.

The kilogram is the primary mass unit in the SI (kg). Even though weight is frequently measured using a spring scale rather than a balancing scale and directly compared with known masses, mass is not the same as weight in physics. Due to the lower gravity on the Moon, an object would weigh less than it does on Earth while maintaining the same mass. Given that weight is a force.

Carbon monoxide (co ) is used as a purifying gas in mond's process to produce nickel from its ores. what type of bonding occurs
ddd [48]
<span>Carbon monoxide has a special type of bond that is a triple bond. The triple bond consists of two covalent bonds in which the elements share some of the outer electrons and then is a dative covalent bond. This is a bond that gives the elements a special kind of group and power in relation to the strength when attempting to break it up.</span>

Write an equation that shows the formation of a selenide ion from a neutral selenium atom
Georgia [21]

Answer:

Se + 2e- => Se-2

Explanation:

Ions are electrically charged particles, formed due to the gain or loss of electrons by an atom.

There are two types of ions cations and anions. An element that loses their electrons and forms positive ions are cations while metals and element that gains one or more electrons and forms negative ions are anions.

Selenium is an atom with atomic number 34 and represented as Se. The electronic configuration of Se is  1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p4. Selenium will gain 2 more electrons to complete it p orbital and form an ion Se-2.

The equation is as below:

Se + 2e- => Se-2

Which noble gas is expected to show the largest deviations from the ideal gas behavior?
yan [13]

Answer:

Radon or Oganesson

Explanation:

Hello,

Considering that the higher both the critical temperature and pressure the higher both the attractive and repulsive intermolecular forces, there will be a larger deviation from ideality for the elements nearer to the 6th or 7th period in group VIIIA (noble gases). Furthermore, their atomic radius is bigger, which increases the probabilities of molecular collisions, circumstance that is neglected in the ideal gas law.

Best regards!
