Answer:

Chromatography involves solvent separation on a solid medium. Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes.

The average speed of the horse for the entire motion is 66.67 m/s.

The given parameters;

The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.

The average speed of the horse is calculated as follows;

[tex]average\ speed = \frac{distance}{time} \\\\average\ speed = \frac{1000 \ m}{15 \ s} = 66.67 \ m/s[/tex]

Thus, the average speed of the horse for the entire motion is 66.67 m/s.

When you rub an inflated balloon on your head and it makes your hair stand up, the force that makes the hair stand up is known as static electricity.

When the balloon is rubbed on the head, electrons from the hair atoms move into the balloon, thus making the balloon to be negatively charged and the hair positively charged due to loss of electrons.

Unlike charges attracts. Thus, when you try to pull the balloon away slowly, the positively charged hair and the negatively charged balloon will attract each other and this is usually what makes the hair stand up.

More on static electricity can be found here: https://brainly.com/question/24160155

Answer:

static electricity

Explanation:

this is because there is an imbalance between negative and positive charges

when you keep on rubbing, a negative charge is created which is carried by electrons.

when you pull the balloon away slowly, the opposite charges attract to each other which makes your hair attract to the balloon

The energy of a photon that has a frequency of 2.3 x 10¹⁴ Hz is 1.524 × 10-¹⁹J

HOW TO CALCULATE ENERGY OF A PHOTON:

E = hf

Where;

E = energy of photon (J)

h = Planck's constant (6.626 × 10-³⁴J)

f = frequency of photon (Hz)

E = 6.626 × 10-³⁴ × 2.3 × 10¹⁴

E = 15.24 × 10-³⁴+¹⁴

E = 15.24 × 10-²⁰J

E = 1.524 × 10-¹⁹J

------> Nồng độ mol của dd AgNO3 đã tham gia phản ứng= [tex]\frac{0,1}{0,4}[/tex]=0,25(M)

It is appropriate to form double or triple bonds in a Lewis structure when four or six electrons are shared.

A Lewis structure is a representation of a molecule using dots to show the valence electrons in the molecule. This dots are shown around the symbols of the elements.

However, in instances where four or six electrons are shared between bonding atoms, a double or triple bond is used. A double bond means that four electrons are shared. A triple bond means that six electrons are shared.

              4. (Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.)

              5. (Fe and S have a covalent bond, and S and O have covalent bonds, too.)

Explanation:

Ye, have great day.

The periodic table is an arrangement of elements according to their periodic properties.

Polar covalent bonds are those compounds in which unsymmetrical electron distribution in bonds leads to polarity in the molecule. Examples of such compounds include; HCl, CHCl3, etc. A polar covalent bond occurs when the electronegativity differences between atoms lies within the range of 0.5 to 1.

Since electronegativity increases across the period and we also know that highly electropositive metals(having very low electronegativity) and highly electronegative nonmetals(having high electronegativity)  form a strong ionic bond, it follows that fluorine (F) and cesium (Cs) will form a strong ionic bond.

A poly atomic ion is an ion that contains more than one atom. Given the options listed NH4^+ is an example of a polyatomic ion.

The difference between polar and nonpolar covalent bonds is that polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.

In FeSO4, Fe and S have an ionic bond, while S and O have covalent bonds.

c. chlorine, with an outer electron shell filled with 7 of a possible 8 electrons

Explanation:

Hope this helps!

The structure in the option A has 7 electrons in the outer shell of its electronic configuration , is unstable and so is most likely to form bond with another atom.

Electrons are arranged in various shells around the nucleus , this arrangement is called electronic structure or configuration.

Each shell can occupy certain fixed number of electrons.

Beside Option A , all the other configurations show stable structures as the last shell has eight electrons and are stable according to the octet rule.

The structure in the option A has 7 electrons in the shell and so is most likely to form bond with another atom.

A non-covalent interactions between  molecules are van der Waal's forces and hydrogen bonds.

Non-covalent interaction is an interaction which does not involve sharing of electrons and in this aspect it differs from covalent bond.It rather involves dispersed variations  of electromagnetic interactions  which are present between the molecules or within the molecule.

The energy released during the formation of these interactions  is of the order of 1-5 kcal .They are classified as electrostatic, pi effects , van der waals forces  and hydrophobic effects.

They are important in maintaining the three dimensional structure of large molecules such as proteins ,nucleic acids ,etc.They are also involved in biological processes . They heavily influence drug design process and design of materials.
