B. Physical weathering

Answer: Physical Weathering

Explanation: It is physical weathering because it is caused by natural elements causing the rock to break. It is not chemical weathering because it is not using any chemical reaction to break the rock. It is not erosion or deposition because it is still not finished with the process with breaking the rock. Think of it this way:

Step 1: Weathering - Breaks rock/stone

Step 2: Erosion - Taking the small bits of rock

Step 3: Deposition - Dropping the rock

Which of the following statements about electronegativity are true? (Select that all apply)

Answers

Answer: The question is incomplete and the options are not given but here are d options from another website.

a. Electronegativity increases as you move to the right of the periodic table.

B. Electronegativity is the ability of an atom to attract electrons.

c. A very electronegative atom easily gives up electrons.

d. Electronegativity increases with a decreased number of protons.

The correct options are

a. Electronegativity increases as you move to the right of the periodic table.

B. Electronegativity is the ability of an atom to attract electrons.

d. Electronegativity increases with a decreased number of protons.

Explanation:

This is because Electronegativity is the ability of an element to attract pair of electrons to itself.

Electronegativity increases as a result of increase in protons and when there is more electron pull.

As, the size of an element decreases, the valence electrons are attracted near to the nucleus. Therefore, there is increase in attraction between shared electron and nucleus.

When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(II) sulfate PbSO4 is reduced to lead at the cathode and oxidized to solid lead(II) oxide PbO at the anode. Suppose a current of 96.0A is fed into a car battery for 37.0 seconds. Calculate the mass of lead deposited on the cathode of the battery.

Answers

Answer: 3.73 grams

Explanation:

[tex]Q=I\times t[/tex]

where Q= quantity of electricity in coloumbs

I = current in amperes = 96.0 A

t= time in seconds = 37.0 sec

[tex]Q=96.0A\times 37.0s=3552C[/tex]

The reaction at cathode is:

[tex]Pb^{2+}+2e^-\rightarrow Pb[/tex]

[tex]96500\times 2=193000Coloumb[/tex] of electricity deposits 1 mole of  

3552 C of electricity deposits =[tex]\frac{1}{193000}\times 3552=0.018moles[/tex] of Pb

[tex]\text {mass of Pb}={\text{moles}\times {\text{Molar mass}}[/tex]

[tex]\text {mass of Pb}={0.018}\times {207.2g/mol}=3.73g[/tex]

Thus mass of lead deposited is 3.73 g

Answers

Just unit conversions here. 450 g / 0.665 g/mL ≈ 677 mL of gasoline

The area covered by the matter is called volumes. Each matter has its own volume and surface area.

The correct answer to the question is 677ml of gasoline.

The formula is used for the question is as follows:-

[tex]M = D*V[/tex]

All the data given in the question is as follows:-

M is 450gD is 0.665

After putting in the equation, the volume we get is as follows:-

[tex]\frac{450 g }{0.665} = 677mL \ of\ gasoline[/tex]

When we report the concentration of a solution we are using the moles of the entire compound.

a. True
b. False

Answers

Answer:

b. False

Explanation:

The formula to find the concentration of a solution is we simply divide the number of moles of the solute with total solution volume in liters. This gives the molar concentration of a solution. Clearly we do not use the number of moles of the entire compound but only that of solute.

Hence, we can conclude that the given statement is false.

Do all materials respond to heat in the same way? Give an example to support your answer.

Answers

Answer:

yes.

Explanation:

Energy transfer will continue until the objects are at the same temperature. There are 3 ways in which thermal energy can be transferred from one object/substance to another, or from a system to its surroundings: Conduction. Convection.

All materials do not respond to heat in the same way because every material is made up of different arrangements of atoms and different substances, and different substances respond differently when reacting with heat.

What is heat?

Heat is a form of energy that is produced by the burning of something. It is thermal energy that increases the warmth of a body or an atmosphere.

As long as the objects are not at the same temperature, energy transfer will continue. Three methods exist for transferring thermal energy from one thing or thing to another, or from a system to its surroundings: Conduction. Convection.

Thus, because each material is made up of a unique combination of atoms and substances, and because each substance reacts to heat in a unique way, no two materials react to heat in the same way.

What observations and reasoning led to the development of Hubble's Law?

Answers

Answer:

Hubble's law says that the universe is expanding outward.

Explanation:

Actually Hubble's law was discovered before the Big Bang theory was formulated. The Big Bang Theory is an attempt to explain the observations that led to Hubble's Law.Before the 1900s the theory was that the universe was eternal and self existent. The idea was that the universe was in a steady state having always existed and would always continue to exist. Albert Einstein even changed the equations in his general theory of relativity to reflect the idea of a steady state. Later he called putting in a fudge factor to result in a steady state the worse mistake of his life.

Hubble observed that most of the universe has a red shift indicating that the universe is expanding and moving away from itself. The further out that the universe is observed the faster it is moving apart.

These observations were inconsistent with a steady state universe.

The Big Bang theory extrapolated backwards. If the universe is expanding and spreading out from itself then further back in time the universe was closer together. The Theory explained Hubble's observations by the idea that at the beginning of time ( for our universe) all the matter and energy were together in one place.

This super dense ball of matter and energy then exploded outwards creating space and time as it is presently observed. The question was would the forces of gravity and black holes bring the matter and energy back together again. The answer found in 1998 was no. The rate of the expansion of the universe is increasing not slowing down and the universe will not collapse back into the super dense ball of matter that it began as.

The Big Bang Theory postulated based on the empirical evidence that our universe had a beginning and it will eventually cease to exist. The conclusion based on Hubble's observations is that matter and energy are not eternal and self existent.
