Answers

The volume = 6.71 L

Further explanation

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

V₁=7 L

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

Element 3 is a metal and Element 1 is a metalloid. Element 2 is the same element as Element 3. Element 1 has very similar chemical properties as Element 4. Element 2 has very similar chemical properties as Element 4.​

Answers

Answer:

The correct option is "Element 2 has very similar chemical properties as Element 4"

Explanation:

Both element 2 and element 4 have the same number of valence electrons; meaning they will be found in the same group (group 1) of the periodic table. Elements in the same group of the periodic table exhibit similar chemical properties. For confirmation, element 2 is sodium (based on the atomic number of 11 provided) while element 4 is rubidium (based on the atomic number of 37 provided) - the two elements are found in group 1 of the periodic table.

NOTE: Number of protons is the same as atomic number

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.

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.

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.

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.

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

Hey There!_____________________________________Answer:

[tex]\huge\boxed{Option D}[/tex]

Solution:

a liquid mixture in which the the solute which is in a smaller proportion is uniformly distributed within the the solvent which is the major component is called a solution.

_____________________________________Option AStirring the substance together vigorously:

It increases the rate of reaction,  because when we stir the solute in the solution, the mixed solute particles are distributed more further than when they are left stationary, making the environment (which surrounds the solute) less concentrated by the dissolved solute thus the rate increases and more solute is mixed.

Option BDissolving the reacting substance in water:

No, A reacting substances  in water are those which can react with water that are Ionic metal. Water is made of ions [tex]H^+ and OH^-[/tex]. Substances(solute), they mix or dissolve more because Solutes ions interact with the ions of a water(solvent), thus breaking the bonds between the solute and then ions of solute form bond with the ions of water. Thus the rate increases in water.

Option CIncreasing the temperature increases the rate of reaction:

No, because by the increase in temperature, the kinetic energy of more  molecules of a substance increase which results in reaching the threshold energy(minimum energy required by the molecules to change into product) of more molecules. So less molecules are left with low energy.

Option DDecreasing the temperature decrease the rate of reaction.

Yes, the rate of reaction decreases because  the molecules are slower and collide less. Less molecules make the effective collisions due to which the kinetic energy of molecules is less, so less molecules make up to the threshold energy. So decrease in temperature lowers the rate of the reaction.
