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 1

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!

Answers

Answer:

C. Boiling Point

Explanation:

A to B represents heat being added to the substance in a solid state, making B to C the melting point. C to D represents heat being added to the substance in a liquid state, making D to E the boiling point as the liquid is converted to a gas.

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

Tetrachloroethene, C2C14 is a solvent used in many dry cleaning processes.
Write the empirical formula for tetrachloroethene.

Answers

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.

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.

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

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.

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

Insects belong to the class Insecta, and arachnids to the class Arachnida; both classes fall under the Arthropoda phylum, along with crustaceans (crabs, lobster and shrimp). All arthropods have an exoskeleton and jointed legs. They have segmented bodies and appendages, which are divided into different segments. Arachnids belong to an even larger group of animals called “arthropods” which also include insects and crustaceans (lobster, crabs, shrimp, and barnacles).
