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

I’m giving 67 points!

Answers

Answer 1

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!

Explanation:

The graph is a graph of the solid, liquid, vapour phase change diagram.

In phase 1, the substance is ice which is the solid phase.

In phase 2,it undergoes melting in a forward reaction.

In phase 3, the melting from phase 2 has now changed to water which is liquid phase.

In phase 4, the substance is undergoing a forward reaction known as evaporation.

In phase 5, the evaporation from stage 4 will turn the liquid into vapour known as the gas phase.

It takes 2 g of chlorine to sanitize 1,000,000g of water. How much chlorine will it take to sanitize a 40,000-gallon pool? ( 1 gallon =3.7L; the density of water is 1.0g/ml ) Show your work

Answers

Answer:

0.1g (Gallon) of chlorine

Explanation:

Formula

1 gallon = 3.7L; the density of water is 1.0g/ml

Given

2g (gallon) of chlorine to sanitize = 1,000,000g (gallon) of water

Solve

If 2g (gallon) chlorine = 1,000,000g (gallon)

∴, ? chlorine = 40,000

The First step; set up an equation

1000000/2 = 40000/?

The Next step; divide 1 million to 2

1000000 ÷ 2 = 500000

Then, divide the result by 40000

40000 ÷ 500000 = 0.08

In the nearest unit that is 0.1

Therefore, it will take 0.1g (gallon) of chlorine to sanitize a 40,000-gallon pool.

Answer:

296

Explanation:

1 gallon = 3.7 L

40,000 gallon

= 40,000 × 3.7

= 148,000 L

1 g = 1 / 1000 L

1,000,000 g

= 1,000,000 / 1000

= 1,000 L

Let x be the amount of chlorine that will it take to sanitize a 40,000-gallon pool.

2 : 1,000 : : x : 148,000

2 / 1,000 = x / 148,000

x × 1,000 = 2 × 148,000

x = ( 2 × 148,000 ) / 1,000

= 2 × 148

x = 296 g

Therefore,

296 g of chlorine will it take to sanitize a 40,000-gallon pool.

The heat of vaporization of a liquid is 84.0 J/g. How many joules of heat would it take to completely vaporize 172 g of this liquid at its boiling point?

Answers

Answer:

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Explanation:

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to Q = m*L, where L is called the latent heat of the substance and depends on the type of phase change.

During the evaporation process, a substance goes from a liquid to a gaseous state and needs to absorb a certain amount of heat from its immediate surroundings, which results in its cooling. The heat absorbed is called the heat of vaporization.

So, it is called "heat of vaporization", the energy required to change 1 gram of substance from a liquid state to a gaseous state at the boiling point.

In this case, being:

Q=?m= 172 gL= 84 [tex]\frac{J}{g}[/tex]

and replacing in the expression Q = m*L you get:

Q=172 g*84 [tex]\frac{J}{g}[/tex]

Q=14,448 J

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

El acido nitrico se obtiene industrialmente por oxidacion de amoniaco (nh3), de acuerdo con la ecuacion: 4nh3 + 702 - h2o + hno2 + 2hno3 ¿ cuanto acido nitrico del 90% de pureza se podra obtener a partir de 1.36 kg de amoniaco?

Answers

Answer:

2800 g de ácido nítrico

Explanation:

La ecuación por la oxidación de amoniaco es:

4NH₃  +  7O₂  →  4H₂O  +  2HNO₂  +  2HNO₃

Si pensamos que el oxígeno es el reactivo limitante, trabajamos con el amoniaco. Convertimos su masa a moles:

1.36 kg = 1360 g

1360 g . 1mol  /17g = 80 moles

Si 4 moles de amoniaco pueden producir 2 moles de acido nítrico

80 moles producirán, (80 . 2)/4 = 40 moles.

Convertimos los moles a gramos:

40 mol . 63g /mol = 2520 g

Si le aplicamos la pureza

2520 g . 100/90 = 2800 g

Chemical reactions follow the law of conservation of mass. This is seen on paper as a balanced equation. Explain the law of conservation of mass and how to balance an equation.

Answers

The law of conservation of mass states that. “The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another”. According to the law of conservation of mass, the mass of the reactants must be equal to the mass of the products for a low energy thermodynamic process.

I’m pretty sure that when balancing a chemical equation no one is thinking about the conservation of mass. It’s all about counting atoms. When you have the same number of each kind of atom on either side of the arrow, then the equation is balanced. Now, that’s not to dismiss the law of conservation of mass which is verified upon closer inspection of the balanced equation.

eg CH4 + O2 → CO2 + H2O - needs balancing.

you use the idea that each type of atoim is conserved - so looking at this you can see it is not currently correct. On the LHS there are 2 O atoms and on the RHS there are 3 O atoms- the number of atoms must remain unchanged. We dont bother about their mass ( although mass is conserved)’

Answer:

2. 2Mg + O2 = 2MgO

Explanation:

make sure that the number of atoms of each element is the same on each side of the equation  

1. 2Na + 2HCl = 2NaCl =H2

on LHS of equation,

Na = 2

H = 2

Cl =2

On RHS of equation,

Na=2

H= 2

Cl =2

2. 2Mg + O2 = 2MgO

on LHS of equation,

Mg = 2

O2 = 2

On RHS of equation,

Mg = 2

O2 = 2

DUE TONIGHT. LINKS DONT WORK SO PLS SHOW WORK. THANK YOU SO MUCH

Answers

Answer:

14°C

Explanation:

In order to use the ideal gas law, you need the number of moles of N2 present.

30.1 g x (mol / 28.02 g) = 1.07 mol N2

Use the ideal gas law: PV = nRT

Now isolate for T(temperature) and plug in your other values:

T = PV / nR

T = (25.2 atm)(1.00 L) / (1.07 mol)(0.08206)

T = 287 K

T(°C) = 287 K - 273 K = 14°C

Therefore, the temperature is 14°C
