I believe the Correct answer would be A

Answer:

The Rutherford atomic model stated that an atom is mostly an empty space that consist of nucleus and electrons, where nucleus is positively charged and electrons are negatively charged.

But Rutherford atomic model missed to add the quantum mechanics or energy level for electrons. Rutherford was unable to make understand the planetary movement of electrons around nucleus and later Bohr's model explained it.

Hence,  Rutherford's model of the atom missed to explain the planetary movement of electrons around nucleus.

Answer: gravitational energy

Explanation: If you have a book on a table and it might fall, its using gravitational energy because its depending on gravity to choose rather it will fall or just balance. It also depends on how high the object is off the ground

Answer:

Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is very different from that of covalent and ionic bonds. ... In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.

A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte until the reaction is complete

Answer:

D

Explanation:

Answer:

3.02x10²⁴

Explanation:

To solve this problem we need to use Avogadro's number: It is the number of units (usually atoms or molecules, in this case it's trucks) contained in one mol: 6.023x10²³.

We multiply the given number of moles times Avogadro's number:

5 * 6.023x10²³ = 3.02x10²⁴

So five moles of trucks would be 3.02x10²⁴ trucks.

This question is incomplete, but it can be answered based on general knowledge of the topic. The answer is RED

Explanation:

This question is describing a gene that codes for color. The allele for red color is R while that of white is r, however, these two alleles exhibit incomplete dominance to form an intermediate phenotype that is PINK (Rr).

Since the heterozygous is pink color, it will take two red alleles to make a plant phenotypically red i.e RR. Note that, genotype "rr" will be white.

Answer:

1. Covalent Bond

2. Ionic Bond

Explanation:

Covalent bonds are defined as the bond in which sharing of electrons takes place between atoms. The sharing of electrons is in equal number so that it form a stable balance of attraction and repulsion between atoms. In the given example of CO2 (first image) oxygen is sharing equal number of electrons with carbon to form a stable bond called covalent bond.

Ionic bonds are formed when valence electrons are transferred to other atoms and form oppositely charged ions. In ionic bond formation, the atoms that gain electrons become negatively charged and the atoms that loses electrons become positively charged. In the given example of Ca Cl2, Ca is also giving its 2 valence electrons to each Cl and there is no stable balance of attraction and repulsion between atoms.

Hence, the correct answer is:

1. Covalent Bond

2. Ionic Bond

Answer:

The speed will be 42 m/s

Explanation:

Wavelength is the minimum distance between two points on the wave that are in the same state of vibration. In other words, in a periodic wave the wavelength is the physical distance between two points from which the wave repeats.

Frequency (f) is the measure of the number of cycles or repetitions of the wave per unit of time. That is, it is the number of vibrations that occur in a unit of time. That is, how many peaks or valleys are repeated in a unit of time. If the unit of time is one second then the frequency is measured in Hertz (Hz).

The wavelength (λ) and the frequency (f) are two inversely proportional parameters and related by the propagation speed. The speed of propagation is the speed with which the wave travels, it is represented by the letter "v". The equation that links these three parameters is v = f * λ.

In this case:

Replacing:

v= 14 Hz* 3 m

Solving:

v= 42 m/s

The speed will be 42 m/s
