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.

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!

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

The question is incomplete, the complete question is;
The levels of organizations in multicellular organisms are shown below, but they are not in the correct order. Arrange the levels of organization in order from simplest to most complex. tissues organs whole organisms organ systems
Answer:
tissues --> organs --> organ system --> whole organisms
Explanation:
The levels of organizations in multicellular organisms refers to the increasing complexity of the components of the organism.
A tissue is an aggregation of cells hence it is the lowest level of organization here.
Organs are an aggregation of tissues, this is the next higher level of organization.
Organ systems are an aggregation of organs, this is the next higher level of organization.
Whole organisms are an aggregation of organ systems. This is the highest level of organization.

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

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.

Tetrachloroethene, C2C14 is a solvent used in many dry cleaning processes.

An empirical formula presents the atoms of all the elements with the most simplified whole number ratios. In other words, divide each subscript by their greatest common factor.
The greatest common factor of 2 and 4 is 2.
2/2 = 1
4/2 = 2
So, the empirical formula for tetrachloroethene is CCl₂.
