how does dipping an iron bucket in Molten zinc protect it?​

Answers

Answer:

It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc. The zinc protects its base metal by corroding before iron.

Explanation:

Answer:

It protects it from corrosion.

Explanation:

Zinc protects iron and steel from the relentless forces of corrosion. Galvanizing iron and steel by dipping them in molten zinc creates an alloy that can, in the right environmental conditions, protect the iron or steel beneath it for 100 years or more.

A 10.150g sample of a compound known to contain phosphorus and oxygen yields 5.717 g of oxygen. Find the empirical formula of the compound

Answers

Answer: The empirical formula is [tex]P_2O_5[/tex]

Explanation:

Mass of O = 5.717 g

Mass of P= (10.150-5.717) g = 4.433 g  

Step 1 : convert given masses into moles.

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{5.717g}{16g/mole}=0.357moles[/tex]

Moles of P=[tex]\frac{\text{ given mass of P}}{\text{ molar mass of P}}= \frac{4.433g}{31g/mole}=0.143moles[/tex]  

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For O = [tex]\frac{0.357}{0.143}=2.5[/tex]  

For P =[tex]\frac{0.143}{0.143}=1[/tex]

The ratio is to be converted to whole number

Thus whole number ratio of O : P = [tex]2.5\times 2:1\times 2=5: 2[/tex]

Hence the empirical formula is [tex]P_2O_5[/tex]

A gas has an initial volume of 15 L. If the temperature increases from 330 K to 450 K, what is the new volume.

Answers

Answer:

20.(45)L or about 20.4545L

Explanation:

PV = nRT

Where:

P - pressure

V - volume

n - number of particle moles

R - a constant

T - temperature in K

We can assume the P and n (and definitely R) stay the same, so we infer that

[tex]V_1 = \frac{nRT_1}{P} = 15L\\V_2 = \frac{nRT_2}{P}\\V_1 / V_2 = \frac{nRT_1}{P} / \frac{nRT_2}{P} = \frac{T_1}{T_2}\\\\15L / V_2 = \frac{330K}{450K} = \frac{11}{15}\\\\V_2 = 15L \cdot \frac{15}{11} = 20.(45)L[/tex]

Which of these cannot be
a source of centripetal force?
A. mass
B. friction
C. electric force
D. gravity

Answers

Answer:

D. Gravity

Explanation:

Gravity cannot be a source of centripetal force. Gravity is the force of attraction from between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface; “gravitation cannot be held responsible for people falling in love” with Albert Einstein.

It manner that is serious and solemn. A solemn and dignified feeling.

Therefore, the correct answer is d. gravity.

A. mass

Mass never provides any force. It is what forces act on. Friction acts as a centripetal force on roads when you’re turning in a circle. Gravity acts as a centripetal force for things like satellites and rockets that orbit Earth and other planets. I’m less familiar with electric force, but I’m sure it can work as centripetal force too. Mass is the only option here that isn’t even a force.

Answer:

A. 650 moles of sulphur.

B. 30 g of FeS₂

Explanation:

The balanced equation for the reaction is given below:

Fe + 2S —> FeS₂

From the balanced equation above,

1 mole of Fe reacted with 2 moles of S to produce 1 mole of FeS₂.

A. Determination of the mole of sulphur needed for the reaction.

From the balanced equation above,

2 moles of S reacted to produce 1 mole of FeS₂.

Therefore, Xmol of S will react to produce 325 moles of FeS₂ i.e

Xmol of S = 2 × 325

Xmol of S = 650 moles

Thus, 650 moles of sulphur are needed for the reaction.

B. Determination of the mass of FeS₂ produced by the reaction of 0.5 mole of sulphur.

From the balanced equation above,

2 moles of S reacted to produce 1 mole of FeS₂.

Therefore, 0.5 mole of S will react to produce = (0.5 × 1)/2 = 0.25 mole of FeS₂.

Finally, we shall determine the mass of 0.25 mole of FeS₂. This can be obtained as follow:

Mole of FeS₂ = 0.25 mole

Molar mass of FeS₂ = 56 + (32×2)

= 56 + 64

= 120 g/mol

Mass of FeS₂ =?

Mass = mole × molar mass

Mass of FeS₂ = 0.25 × 120

Mass of FeS₂ = 30 g

Thus, 30 g of FeS₂ were obtained from the reaction.

Answers

Answer:

8.8g of ammonium chloride would be undissolved.

The solubility of ammonium chloride at 80°C is: 65.6g / 100mL

As the solubility is 65.6g / 100mL, in 200g = 200mL the solubility will be:

65.6g * 2 =

131.2g / 200g

That means the water at this temperature will dissolve 131.2g of ammonium chloride. As were placed 140g, the mass that will be undissolved is:

1)Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays.

2)The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point.

3)When the object is located at the focal point, no image is formed. As discussed earlier in Lesson 3, light rays from the same point on the object will reflect off the mirror and neither converge nor diverge.

What is refraction of sound wave ?

An important case in which sound waves change form or spread out is called refraction. This phenomenon affects the bending of a sound wave owing to changes in the wave's speed.

Refraction is the reason ocean waves near a shore parallel to the beach and why glass lenses can be used to focus light waves.
