Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie

One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.

if one species of rabbit, the gene for brown fur ( B) is dominant, while the gene for black fur ( b) is recessive. One rabbit has the dominant allele for brown fur and the recessive allele for black fur. Another rabbit has two recessive alleles. If the two rabbits have offspring, what are the odds of one of the offspring having brown fur?

Answers

Answer:

1/2

Explanation:

According to this question, the gene coding for fur color in rabbits contains two alleles viz: alelle for brown fur ( B) is dominant, while the allele for black fur ( b) is recessive. This means that an heterozygous rabbit (Bb) will have brown fur.

Based on the question, one rabbit has the dominant allele for brown fur and the recessive allele for black fur i.e genotype Bb, another rabbit has two recessive alleles i.e. genotype bb. If these two rabbits cross i.e. Bb × bb, the proportion of the offsprings produces will have Bb, Bb, bb and bb genotype.

Bb is dominant, hence, 1/2 of the offsprings will be brown furred.

Why do lunar and solar eclipses not happen every month?
-Eclipses only occur during full and new moons.
-Earth rotates around its axis faster than the moon.
-The moon and Earth only travel through the penumbras.
-The moon’s axis does not always align with Earth’s shadow.

Answers

Answer:

i think its the last one

Answer: The moon’s axis does not always align with the Earth’s shadow.

The moon does rotate around the Earth every month but that doesn’t mean it can get a shadow every time due to the moon’s tilted path around the Earth.

We apply the same amount of energy to 10.0-g samples of aluminum, iron, and silver which begin at the same temperature. Rank the metals from highest to lowest temperature after the heat is applied

Answers

Answer:

Ag > Fe > Al

Explanation:

The values of the specific heat capacity of the elements are given as;

Aluminum = 0.897 J/g*K  

Iron=0.449 J/g*K  

Silver=0.235 J/g*K

Specific heat capacity basically refers to how much heat is required to change the temperature of a unit mass of a substance by a degree. Elements with high specific heat capacity would require higher energy compared to elements with lower values,

Aluminium (Al) has the highest specific heat capacity, hence it wold require more energy to cause a change in temperature. Aluminium would be the lowest.

Silver (Ag) has the lowest specific heat capacity hence it would require less energy to cause a change in temperature. Silver wold be the highest.

The middle would be iron (Fe).

The rank is given as;

Ag > Fe > Al

How can the gravitational potential energy of an object be changed?

Answers

Answer:

Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).

b. Correctly identify and draw the location of the central atom and surrounding atoms. (2pt)
c. Correctly draw the total amount and location of the electrons on the lewis structure. (2pt) ​

Answers

Answer:

For CH3Br, there are a total of 14 valence electrons. Hydrogen always goes on the outside, and since Carbon is less electronegative than Bromine, we'll put the Carbon in the center and the Bromine on top. We have 14 valence electrons for the CH3Br Lewis structure. Put two between atoms to form chemical bonds.

Teresa creates an experiment Washington states to read colored substances together in a container in observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after 8 minutes. What does this represent about the type of change happening in the container

Answers

The question is incomplete, the complete question is;

Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container? A chemical change started immediately and finished at eight minutes. A non-chemical change started immediately and finished at eight minutes. A chemical change occurred at four minutes. A non-chemical change occurred at four minutes.

Answer:

A chemical change started immediately and finished at eight minutes.

Explanation:

A chemical change is one in which a new substance is formed. One of the indicators that a chemical change has occurred is the change in the color of the system from red to blue.

The question clearly stated that the change occurred gradually. This means that the reaction must have started immediately the substances were mixed and went on to conclusion after eight minutes when the complete blue color appears.

A sealed can of soda contain a pressure of 1.15 atm at 23°C. What is the new pressure at 79 °C? Report your answer to the hundredths place (two decimal places) You do NOT need units in your answer

Answers

Answer:

P₂ = 1.37

Explanation:

Given data:

Initial pressure = 1.15 atm

Initial temperature = 23°C (23+273= 296 K)

Final pressure = ?

Final temperature = 79°C (79+273=352 K)

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.15 atm / 296 K = P₂/352 K

P₂ = 1.15 atm × 352 K / 296 K

P₂ = 404.8 atm. K /296 K

P₂ = 1.37 atm

2 H2 + 2Cl2 > 2 HCl
H2 + Cl2 > 2HCl
H2 + Cl2 > HCl

Answers

Answer:

H₂ + Cl₂ → 2HCl

Explanation:

The equation that is balanced and follows the law of conservation of mass is:

 H₂ + Cl₂ → 2HCl

Based on the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but they combine with one another".

It suggests that the number of species on both sides of the expression must be the same.

 For the given reaction:

        H₂ + Cl₂ → 2HCl

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options: True False

Answers

Answer:

True

Explanation:

The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.

Electromagnetic waves are waves that do not require a material medium for their propagation. They are able to pass through vacuums and mediums with particles at constant speed. It is mechanical waves whose speed is medium dependent. Mechanical waves have varying speed based on the mediums they move through.
