Answer:

the concentration of the solution is 2 mol/L.

Explanation:

Molarity is defined as the concentration of a solution expressed in terms number of moles of solute per liter of solution.

Mathematically Molarity is expressed as follow;

[tex]Molarity = \frac{Moles \ of \ solute}{Liters \ of \ solution} \\\\[/tex]

Given;

Volume of the solution, V = 0.45 L

Moles of the solute, n = 0.9 moles

The concentration of the solution [tex]= \frac{0.9}{0.45} = 2 \ mol/L[/tex]

Therefore, the concentration of the solution is 2 mol/L.

Answer:

mudslide

Explanation:

a mass of mud and other earthy material that is falling or has fallen down a hillside or other slope

Answer:

the outer core is important because the outer core is responsible for earth's magnetic field which protects earth from harmful particles that comes from sun and also contains some natural metal like nikle and iron.

is this much paragraph enough comment down below..

Explanation:

Have a good day!!!

Answer:

higher frequency

Explanation:

Answer:

2.96 L

Explanation:

We apply the Ideal Gases Law to determine this:

P . V = n . R . T

Firstly we need to know the pressure for the 2.25 moles

P . 1.80L = 2.25 mol . 0.082 L.atm/mol.K . 298K

(We convert T°C to T°K, 25°C + 273 = 298K)

P = (2.25 mol . 0.082 L.atm/mol.K . 298K) / 1.80L

P = 30.5 atm

So now, we apply the pressure value for the new conditions:

30.5 atm . V = 3.7 mol . 0.082 . 298K

V = (3.7 mol . 0.082 . 298K) / 30.5atm = 2.96 L

Answer:

d

Explanation:

they would all have the same volumes

Answer:

15.5g

Explanation:

"The total mass of both chemicals and the containers they are in is 15.5 g." After a chemical reaction, by conservation of mass, the total mass of the products and the two containers after reaction is the same at 15.5g.

Answer:

15.5

Explanation:

in a chemical reaction, mass is conserved

so mass after reaction = mass before reaction = 15.5 g

Answer:

The list of elements from increasing electronegativity: Calcium <  magnesium < chlorine < argon < boron.

Explanation:

In the periodic table if you move from left to right there would be an increase in the electronegativity of the elements. If you move from the bottom to the top of the groups in the periodic table the electronegativity increases and if u move to the bottom from down its decreases.

Calcium is in the 2nd group below magnesium so calcium is the least electronegative among given elements then magnesium and then chlorine as it is top of magnesium then argon, as it is right to the chlorine, and boron has the most electronegativity as it is above rest of the elements.

Answer:

when they have satisfied the octet rule naturally or through bonding to obtain full valence shells

Explanation:

Generally, most atoms of an element are unstable because they have a void in their electron shell to fill, hence, they need to react with other elements to fulfil this task of octet.

Octet rule states that atoms of elements engage in reactions to form compounds so they can have eight (8) valence electrons in their shell. Noble gases e.g argon, neon etc. are elements that have naturally satisfied this octet rule by possession of 8 valence electrons in their shell. Other elements that do not have this naturally becomes reactive and enter bonding with other atoms to obtain full valence shells.

im not 100% sure but it makes sense

Answer:

0.897

Explanation:

Answer:    1.7x10^-5

Explanation:

pH + pOH = 14

14 - pH = pOH

14 - 9.23 = 4.77

pOH =4.77

[OH-] = 10^-pOH

         = 10^-4.77

         = 1.698243x10^-5

         = 1.7x10^-5

Answer:

Gas giants.

Explanation:

Jupiter, Saturn, Uranus, and Neptune are the gas giants of our solar system.

Answer:

Examples of how the ideas can be applied to the issues and practices of hydraulic fracturing for the acquisition of shale gas are;

Reuse; The produced water in obtained from oil and gas well production are reused for fracking, drilling, and if the water is good enough, it can be used for farming

Reduce; The use of recycled brine and water in drilling and fracking process reduces the application of freshwater in the those processes and reduces pollution of natural water sources

Recycle; Recycling involves creating products from waste. In the hydraulic fracturing process approximately 13 percent of the water produced and the flowback water are recycled to be used more than once thereby reducing the net consumption of freshwater

Explanation:

In hydraulic fracturing, also known informally as fracking, is the drilling method used in oil and gas well development process that makes use of water sand and chemical injection through the well bore to open and widen cracks in the bedrock formations in the areas around the wellbore.

Answer:

protons and neutrons

Explanation:

The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
