Answer:

Explanation:

Calculated it leads to the answer 5.6L

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

Answer:

.084 M

Explanation:

Molar mass of sucrose = 342.3

The formula to find molarity is moles of solute / liters of solution

Since we need to turn grams to moles for this equation we do 104 / 342.3 = 0.304

Now we can use the equation listed above. .304 / 3.6 = 0.084 M

Explanation:

molarity=no. of moles of solute/solution in litres

6.17M=no. of moles of solute/9.4 L

6.17×9.4=no. of moles of solute

57.9 =no. of moles of potassium fluoride KF

no. of moles=given mass /molar mass

Answer:

The only intermolecular forces present in the compound Hexane are London dispersion forces which are generally the weakest. Hexane's molecular structure proves that Dipole-Dipole forces wont exist as there aren't very polar bonds in the structure.

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.

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!

Answer:

Answer:

78878

Explanation:

Answer: B

Explanation:

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

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

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.

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.

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.

Explanation:

Answer:

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).

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
