Chemistry
2 answers:
il63 [147K]3 years ago
5 0

Answer:

The correct answer is :'The gravitational force between two objects is related mathematically to their mass and the distance between them'.

Explanation:

A scientific law is a statement which explains physical phenomena and has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations after each conduct.

A scientific law comes into picture after the acceptance of a theory which explains or exposes the reason behind any physical phenomena occurrence.

So the best example of scientific law:

The gravitational force between two objects is related mathematically to their mass and the distance between them.

Answer:

The ( Any) force is depending proportionally on the mass of an object and the distance the object has to go and due to the magnetic force the earth exerts on every object in the atmosphere, depending on where the weight center of an object on the edge of a table is, will fall on the ground.

Explanation:

And given the newtonian formulae of the vectorial agent called Force as an exponential function of space/ time then we can consider the three statements equally expressing scientific laws in different manners

Which of the following is true of the energy levels of electrons in shells?
anyanavicka [17]

Answer:

Option C is the correct. Valence electrons have a higher energy level than those in other filled shells

Explanation:

Electrons must lose energy to move from the first to the second shell. FALSE

The electrons always win energy to move from the first to the second shell.

All the electrons in an atom have similar energy levels FALSE.

They are not neccesary similar. In hydrogen these are the level energy -13.6 eV , -3.4 eV , -1.51 eV , -85 eV  and -54 eV

Electrons do not have potential energy, just kinetic energy. FALSE

They have both.

Valencia electrons are the last electrons in the last layer. They have as much energy as possible and are responsible for forming bonds with other elements.

Saponification is a chemical reaction _____. A. due to the presence of a strong organic acid. B. that results in an alcohol and
dezoksy [38]

Answer:

that results in an alcohol and a carboxylic acid.

Explanation:

Saponification is a chemical reaction process of alkaline hydrolysis of esters(R'COOR group) by which soap is obtained.

For Example, when a base such as sodium hydroxide [NaOH]  is used to hydrolyze an ester, the products are a carboxylate salt and an alcohol. Because soaps are prepared by the alkaline hydrolysis of fats and oils.

In a saponification reaction, alkaline hydrolysis of fats and oils with sodium hydroxide  yields propane-1,2,3-triol and the corresponding sodium salts of the component fatty acids.

i.e  Fat or oil + caustic alkali ⇒ Soap + propane-1,2,3-triol

As a specific example, ethyl acetate and NaOH react to form sodium acetate and ethanol:

The reaction goes to completion in the image below:

How many moles of chlorine (Cl) atoms are in a sample of 1.72 × 1022 atoms?
Ainat [17]
<span>1mole of Cl atoms contain the Avogadro's number 6x10 exp 23(10 to the power of 23)
there for xmoles of Cl atoms is contained in 1.72x1022atoms
xmoles =1.72x1022 divided by 6x10exp 23
2.93 exp -23moles(2.93 x10 to the power of -23)
