Answer:

A) long distance and long travel time.

Explanation:

Sedimentary rocks are the rocks which are created by the accumulation or the deposition of minute particles as well as subsequent cementation of the  mineral or the organic particles on floor of the bodies of the water at the  surface of the Earth.

Sediment Maturity is the duration of the time that sediments have been in sedimentary cycle. <u>Texturally, mature sediments are that which are well rounded, (the process of rounding for the sediments increases with the transport distance as well as the time) as well as well sorted (the process of sorting for the sediments gets better as the larger clasts are astray and the smaller clasts are carried away , which also means the sediments travel longer distance).</u>

The ionization of pure water forms _____.
Evgesh-ka [11]

Answer: The ionization of pure water forms <u><em>hydroxide and hydronium ions.</em></u>

Explanation:

Ionization is a reaction in the pure water in which water breaks down into its constituting ions that hydronium ion and hydroxide ions.

H_2O+H_2O\rightleftharpoons H_3O^++OH^-

One molecule of water looses its proton to form hydroxide ion and l=the lost protons get associated with another water molecule to form hydronium ion.

An orbital of an atom is defined as the most probable location of(1) an electron (2) a neutron (3) a positron (4) a proton
Montano1993 [528]

Answer: option (1) an electron.


Justification:


1) The plum pudding model of the atom conceived by the scientist J.J. Thompson, described the atom as a solid sphere positively charged with the electrons (particles negatively charged) embedded.


2) The next model of the atom, developed by the scientist Ernest Rutherford, depicted the atom a mostly empty space with a small dense positively charged nucleous and the electrons surrounding it.


3) Then, Niels Bhor came out with the model of electrons in fixed orbits around the nucleous, just like the planets orbit the Sun. So, the path followed by the electrons were orbits.


4) The quantum model of the atom did not place the electrons in fixed orbits around the nucleous but in regions around the nucleous. Those regions were named orbitals. And they are regions were it is most probable to find the electron, since it is not possible to tell the exact position of an electron.


As per this model, the electron has a wave function associated. The scientist Schrodinger developed the wave equation which predicts the location of the electron as a probability.


The orbitals are those regions were it is most likely to find the electron. Those regions are thought as clouds of electrons.

What is solubility in chemistry?
svet-max [94.6K]

Answer:

Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.

If you measure the mass of a liquid is 11.50 g and its volume as 9.03 ml how many significant figures should its density value h
MAXImum [283]

To get a result with the best degree of precision, the number of significant figures should be equal to the smallest number of significant figures of the given numbers. In this case, the smallest is 3 as given by the number 9.03 mL.

Therefore density is:

<span>11.50 g / 9.03 mL = 1.27 g/mL</span>
