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.

Explanation:

explain why the pressure in a sealed container of gas decreases when heat is added to the system?

when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!

IT DOES NOT DECREASE

PV =nrT

IF THE O THEVOLUME IS FIXED (REIN A SEALED CONTAINER) AND THE  NUMBER OF MOLES n is FIXED, THEN THE PRESSURE IS DIRECTLY PROPORTIONAL THE TEMPERATURE

Explanation:

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.

Explanation:

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).

Answer:

elements with low first ionization energies and positive or slightly negative electron affinities generally form cations.

hope it is helpful:)

Answer:

True.

Explanation:

In metallic bonds, nuclei of metal atoms line up uniformly and the electrons are delocalized (spread out evenly). Since this allows electrons to move around freely, and electricity is created by the flow of electrons, metals can conduct electricity.

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.
