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!

58. What is the temperature if 30.1 g of N, in a 1.00-L container is at a pressure of 25.2 atm?
DUE TONIGHT. LINKS DONT WORK SO PLS SHOW WORK. THANK YOU SO MUCH
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

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?
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.

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
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 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.
A) The substance is in the gas phase only in "region 5".
B) The substance is in both the liquid and solid phase in "region 2"
C) The substance is only in the liquid phase in "region 3".
D) The melting point is the temperature at "region 2".

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.
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)’

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?
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

on LHS of equation,
Na = 2
H = 2
Cl =2
On RHS of equation,
Na=2
H= 2

2. 2Mg + O2 = 2MgO
on LHS of equation,
Mg = 2
O2 = 2
On RHS of equation,
