Answer:

The volume of displaced fluid is equivalent to the volume of an object fully immersed in a fluid.

Answer:

Answer is C

Explanation:

C - A molecule with hydrogen bonded to O, N, or F

A molecule with hydrogen bonded to O, N, or F can experience hydrogen bonding. Therefore, the correct option is option C.

A hydrogen atom is attracted to another electronegative atom in a neighbouring molecule when it is connected to a strongly electronegative atom (O, N, or F). This attraction is more powerful than the usual dipole-dipole interactions between polar molecules.

The enormous electronegativity differential between hydrogen and the highly electronegative atom causes hydrogen bonding. The electronegative atom attracts the shared electrons in the covalent link, causing the hydrogen atom to gain a partial positive charge.

Answer:

Metal.

Explanation:

Metal has the smallest iconic radius in the alkaline earth metal.

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.

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.

Correct on EDGE

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

             Reactant side              Product side

H                  2                                   2

Cl                  2                                   2

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.

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).

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

Answer:

When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
