What is geological evolution?

Geological evolution is the process of gradual change and events in antiquity that include the steps to create the Earth.

At first, there was extreme volcanism, later the planet cooled to create the crust. Also, condensed water vapor formed the oceans and seas.

The geological history of Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy).

Geological evolution studies the shape of the globe, how it formed, and the relationships of the different eras and the matter that changed during them.

Therefore, An example of geologic evolution is a gradual change in the size of continents.

A 50.00 L sample of gas collected in the upper atmosphere at a pressure of 18.30 torr is compressed into a volume of 0.1500 L. What is the final pressure?

Answers

Answer:

the ans is in the picture with the steps  

(hope it helps can i plz have brainlist :D hehe)

Explanation:

The concept Boyles law is used here to determine the final pressure of the gas. Boyle's law was put forward by the Anglo-Irish chemist Robert Boyle in the year 1662. The final pressure of the gas is  7.66 atm.

What is Boyles law?

At constant temperature, the volume of a given mass of gas is inversely proportional to its pressure. It can also be explained as at constant temperature, the product of pressure and volume of a given mass of gas is constant.

A straight line graph is obtained when pressure is plotted against the inverse of the volume.

Mathematically the law can be expressed as:

V∝ 1/P

PV = k (Constant)

Here 'V' is the volume and 'P' is the pressure of the gas.

For two different gases, the equation is given as:

P₁V₁ = P₂V₂

P₂ = P₁V₁ / V₂

1 torr = 0.00131 atm

P₁ = 0.023 atm

0.023 × 50.00  / 0.1500 = 7.66 atm

Thus the final pressure is 7.66 atm.

Calculate the volume in mL of 53.2 g of .251M solution of HCl.
Show work please

Answers

Answer:

5.813 mL

Explanation:

You need to use the formula : vol = mass / molar mass x molarity

the molar mass of HCl is 36.46 and the problem gives you the rest of the equation

0.251M x 36.46 = 9.151

53.2g / 9.151 = 5.813 mL

An elastic band with a spring constant of 62 N/m is extended by 0.15 m. What is the force applied to the rubber band?

Answers

Answer:

the force applied to the rubber band is -9.3N

Explanation:

The computation of the force applied to the rubber band is shown below;

We know that

Force in newtons = Spring constant × amount of extension

F = -k × x

where

-k = 62 N/m

And, x = 0.15m

So, the force applied is

= -62N/m × 0.15m

= -9.3N

hence, the force applied to the rubber band is -9.3N

the force applied to the rubber band is -9.3N

NaCl is made from 1 Na and 1 Cl. If I have 45.978 grams of Na, how many grams of NaCl can I make? (You will have to convert to moles of Na first!)
explain answer​

Answers

Answer:

116.88 g

Explanation:

Step 1: Write the balanced equation for the synthesis of NaCl

Na + 1/2 Cl₂ ⇒ NaCl

Step 2: Calculate the moles corresponding to 45.978 g of Na

The molar mass of Na is 22.990 g/mol.

45.978 g × 1 mol/22.990 g = 1.9999 mol

Step 3: Calculate the number of moles of NaCl formed from 1.9999 moles of Na

The molar ratio of Na to NaCl is 1:1. The moles of NaCl formed are 1/1 × 1.9999 mol  = 1.9999 mol.

Step 4: Calculate the mass corresponding to 1.9999 moles of NaCl

The molar mass of NaCl is 58.443 g/mol.

1.9999 mol × 58.443 g/mol = 116.88 g

44 mL of H2CrO4 is needed to neutralize 176mL of a 10M solution of Pd(OH)4. What is the molarity of this solution?

Answers

Answer: The molarity of this solution is 2.5 M.

Explanation:

Given : [tex]V_1 = 44 mL[/tex],           [tex]V_2 = 176 mL[/tex]

[tex]M_1 = 10 M[/tex]

Therefore, the value of molarity of the solution is calculated using following formula.

[tex]M_1 \times V_1 = M_2 \times V_2[/tex]

Substitute the values into above formula as follows.

[tex]M_1 \times V_1 = M_2 \times V_2\\10 M \times 44 mL = M_2 \times 176 mL\\M_2 = \frac{10 M \times 44 mL}{176 mL}\\= 2.5 M[/tex]

Hence, molarity of the solution is 2.5 M.

Calculate the number of water (H2O) molecules produced from the decomposition of 75.50 grams of Iron (III) hydroxide (Fe(OH)3).

Answers

Answer: [tex]6.38\times 10^{23}[/tex] molecules of water are produced.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Fe(OH)_3=\frac{75.50g}{106.8g/mol}=0.707moles[/tex]

The balanced chemical reaction is:

[tex]2Fe(OH)_3\rightarrow Fe_2O_3+3H_2O[/tex]  

According to stoichiometry :

2 moles of [tex]Fe_2O_3[/tex] produce = 3 moles of [tex]H_2O[/tex]

Thus 0.707 moles of [tex]Fe_2O_3[/tex] will produce=[tex]\frac{3}{2}\times 0.707=1.06moles[/tex]  of [tex]H_2O[/tex]  

According to avogadro's law, 1 mole of every substance contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

Thus 1.06 moles of [tex]H_2O[/tex] contains = [tex]\frac{6.023\times 10^{23}}{1}\times 1.06=6.38\times 10^{23}[/tex] molecules

How is pascals law used in the brakes of a car?

I’m giving 67 points!

Answers

Answer:

A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid. With that said; in a hydraulic brake system, if the piston in the master cylinder(the part your foot pushes on) is one inch square area and you push with 100 pounds, then 100 pounds per square inch is transmitted to all parts of the hydraulic system. Now if the brake caliper piston(the part that pushes against the brake pad) is 2 square inches then there will be a total of 200 lbs of force being applied by the wheel cylinder, because each square inch has 100 pounds pushing on it. This is basically how cars brake systems are designed in order to reduce the amount of force required by the driver.

Btw if u want to give 67 points u must multiply that by 2 since two people answer and they get half of 67.    Im still happy with my 34 though!
