What is chemical formula?

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.They are used to describe the chemical reactions.

There are four types of chemical formula:

1)empirical formula

2) structural formula

3)condensed formula

4)molecular formula

How much does a sample of C6H12O6 weigh if it contains 1.7 x 10^28 hydrogen atoms?

Answers

Answer:

Explanation:

Glucose  has    6  number  of  carbon  atoms,  12  atoms  of  oxygen  and   6  atoms  of  oxygen

The  total  number  of  glucose  atom is  24  atoms

The  atom  of  hydrogen is twice  that  of   carbon  

that  is (6.02 x10^22) x2=1.204 x10^23atoms

the  number  of  moles  of  hydrogen  is   solved  as   follows

1mole  =  6.02x10^23 atoms  what   about  1.204 x10^23=

{(1.204x10^23)/(6.02 x10^23)}=0.2moles

The  moles  of  glucose

1   atom  of   glucose=  6.02 x10^22  x4 =2.408 x10^23  atoms

moles= { (2.48 x10^23)/(6.02  x10^23)}=0.41moles

Most metals are NOT ____ ? Liquid at room temperature, ductile, malleable, good conductors of heat and electricity.

Answers

Liquid at room temperature

Most metals are not liquid at room temperature. Therefore, option A is correct.

Most metals are not liquid at room temperature, except for a few specific exceptions such as mercury (Hg) and gallium (Ga). These metals have relatively low melting points, which allows them to exist in a liquid state at or near room temperature.

The majority of metals, however, exhibit a solid state at room temperature. This solid state is characterized by a regular arrangement of atoms or ions in a crystal lattice structure. The strength of metallic bonds holds the atoms together, giving metals their solid and rigid form.

2. What type of bonding would be expected between the following atoms?
a. Li and F
c. I and Br
b. Cu and S
d. S and O

Answers

a.) covalent
c.) covalent
b.) ionic
d.) covalent

Considering the definition of covalent and ionic bond, the type of bonding that would be expected between the following atoms is:

Li and F: Ionic Bond I and Br: Covalent Bond Cu and S: Ionic Bond S and O: Covalent Bond

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas.  

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Taking into account the previous definitions, it is first necessary to know if the elements are metallic or non-metallic:

Lithium Li: Metallic atoms Flour F: Non-metallic atoms Iodine I: Non-metallic atomsBromine Br: Non-metallic atomsCopper Cu: Metallic atoms Sulfur S: Non-metallic atoms Oxygen O: Non-metallic atoms

Now you can determine the type of bond of the following pairs of elements:

Li and F: Metallic atoms - Non-metallic atoms: Ionic Bond I and Br: Non-metallic atoms - Non-metallic atoms: Covalent Bond Cu and S: Metallic atoms - Non-metallic atoms: Ionic Bond S and O: Non-metallic atoms - Non-metallic atoms: Covalent Bond

why is diamond hard​

Answers

The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

Answer: Diamond is hard due to its giant covalent lattice and it has many strong covalent bonds.

Which of the following d shell configurations is likely to be the best magnet?​

Answers

Answer:

D10 is answer

Explanation:

Magnetism can result from unpaired electrons in a given ion of an element, depending on the spin states of the electrons and d10 is fully filled

The d 10 is the d shell configurations which is most likely to be the best magnet.

What are configurations?

Configurations are defined as the way that parts are joined together to form the computer system. The arrangement of electrons scattered throughout the orbital shells and subshells is depicted by the electron configuration of an atom. Divide the periodic table into pieces to represent the atomic orbitals, the areas where electrons are stored, in order to determine an electron configuration. The s-block is represented by groups one and two, the d-block by groups three through twelve, the p-block by groups thirteen to eighteen, and the f-block by the bottom two rows.

Depending on the spin states of the electrons and whether or not d10 is completely filled, magnetism can emerge from unpaired electrons in a specific ion of an element.

Thus, the d 10 is the d shell configurations which is most likely to be the best magnet.

You crumple a piece of paper in your hands. Not all of the kinetic energy from your hands is used to crumple the paper. Where does the rest of the energy go?
A. It is transformed into sound energy.
B. It is transformed into light energy.
C. It is transformed into electrical energy. D. It is transformed into magnetic energy.​

Answers

Answer:

A

Explanation:

When you crumble a piece of paper it make a sound plus i just did on apex

When we crumple a piece of paper in our hands, a part of the energy is transformed into sound energy. Therefore, option (A) is correct.

What is sound energy?

Sound transmits through the medium such as liquids, gases, and plasma in the form of longitudinal waves or compression waves. It requires a medium to propagate as it can travel through solids as both longitudinal and transverse waves.

Transverse sound waves exhibit waves of alternating shear stress perpendicular to the direction of propagation while Longitudinal sound waves exhibit alternating pressure deviations leading to compression and rarefaction.

Generally, waves move matter up and down but do not carry along.  When we crumple the paper with our hands the kinetic energy of our hands is used to deform the paper but at the same time, we can listen to some sound which indicates that some energy is transformed into sound energy.
