what is the mass of the product of 111.6g and 48g

Answer:

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.

The class of small objects with orbits completely between the gas giants is centaurs.

Centaurs are a class of small tiny bodies that circles the Sun amid Jupiter as well as the Neptune, crossing the orbits of one or more of the giant planets. It has a semi-major axis, also known as perihelion, between that the outer planets.

Centaurs' orbits are often unstable since they have crossed the orbits of more than one of the gas giant planets. They are known to have the properties of asteroids and comets.

Explanation:

Denitrifying Bacteria such as Pseudomonas aeruginosa is the type of bacteria that use enzyme nitrate reductase to metabolise nitrogen oxides to nitrogen gas.

Denitrification is the process whereby nitrites or nitrogen oxides is converted to nitrogen gas by a denitrifying Bacteria such as Pseudomonas.

Pseudomonas aeruginosa uses enzyme nitrate reductase to reduce nitrate to nitrite.

Then nitrite is then converted back to nitrogen gas.

Therefore, Pseudomonas aeruginosa is a type of bacteria that uses enzyme nitrate reductase.

Explanation:

Sodium chloride has the highest melting point while iodine has the least melting point.

The melting points of solid substances depends on the nature of intermolecular forces that exists in the substance. The stronger the magnitude of intermolecular forces in a substance, the higher its melting point.

The order of melting points of the solids shown in question is as follows;

Sodium chloride has the highest melting points because it is an ionic substance. Among the molecular sucrose and paraffin, sucrose has a higher melting point than sucrose because it has a greater molar mass. Iodine, a molecular substance has the least molar mass and the least melting point in the list.

Answer:

Nuclear transmutation

Explanation:

The process in which an element spontaneously transforms into another isotope of the same element, or into a different element is called nuclear transumutation. It occurs when the number of protons or neutrons in the nucleus of an atom is changed.

n-propylbenzene will travel the largest distance because it interacts most effectively with the stationary phase followed by phenol and benzoic acid will travel the least distance because it interacts poorly with the mobile phase.

Thin layer chromatography involves the separation of a mixture using a stationary phase made of  silica gel on a glass plate and an appropriate mobile phase. The extent of separation is highly dependent on the magnitude of interaction between the solute and the mobile phase. and stationary phase.

The first step in thin layer chromatography is to make a thin mark at the bottom portion of the plate then spot the plate with the sample. The mobile phase is now introduced into the TLC chamber a little below the mark. The plate is now placed in the stationary phase such that the mark is above the solvent level.

The TLC chamber is now covered and enough time is allowed for separation to occur. The spots can be seen using a suitable indicator dye or with a the aid of UV light

After the  separation of a homogeneous, liquid mixture containing benzoic acid, n-propylbenzene, and phenol, provided a 4:1 hexane to ethyl acetate solution as the eluent, we can see that n-propylbenzene will travel the largest distance because it interacts most effectively with the stationary phase followed by phenol and benzoic acid will travel the least distance because it interacts poorly with the mobile phase.

Answer:

electrical forces between particles, as given by coulombs law.

Explanation:

Properties of a substance such as vapor pressure and surface tension depend on electrical forces between particles, as given by Coulomb's law.

The vapor pressure refers to how easily a liquid converts to gas while surface tension is the force that makes a liquid surface act as a stretched elastic skin.

Both vapor pressure and surface tension has a lot to do with the degree of polarity in a molecule. Usually, polar molecules have a low vapor pressure and high surface tension due to a high electrical forces between particles, as given by Coulomb's law.

PLEASE NOTE THAT THIS IS A EDUCATED GUESS.

Under Normal Conditions no reaction will be seen between Calcium ions (Ca⁺), NaCl (salt solution) and NaOH(sodium hydroxide).

In a double replacement reaction , the compounds present switch cation and anion to form new compounds.

But here in NaOH(sodium hydroxide) and NaCl (salt solution) the cation sodium ion Na⁺, of both the compounds is same so the end result will be same .

There will be no net reaction .

But if excess Sodium Hydroxide is added to the solution , we will see precipitate of NaCl , salt forming.

If Salt contained Ca⁺ ions , firstly NaCl will only combine with Ca⁺ ions in special conditions as Na⁺ ions are more reactive than Ca⁺ ions.

On addition of NaOH we would observe no change in normal conditions due to above stated reason .

In special conditions following reaction takes place ,in normal condition the reaction follows reverse direction.

Ca + 2 NaOH ← Ca(OH)₂ + 2 Na

Hence under Normal Conditions no reaction will be seen between Calcium ions , NaCl (salt solution) and NaOH(sodium hydroxide).
