A ---->gamma ray

Explanation:

Gamma rays have the highest frequencies among all electromagnetic waves and therefore have the shortest wavelengths.

The IUPAC name for the compound shown is 3-ethyl-2,2-dimethylpentane.

International Union of Pure and Applied Chemistry is referred to as IUPAC. The terminology for naming organic compounds has been provided by IUPAC. The root name, prefix, and suffix are the three components that make up an IUPAC name.

There are five carbon atoms in the longest chain. Consequently, pent is the structure's root name. Choose the longest chain where the substituents are represented by the fewest numbers.

On the longest chain, three substituents are present. It consists of one ethyl group and two methyl groups. One ethyl group and two methyl groups are substituted at C-2 and C-3, respectively. Therefore, 3-ethyl-2,2-dimethyl will be the prefix. Alkane makes up the functional group. Therefore, the suffix is ane.

This ends up naming the compound as 3-ethyl-2,2-dimethylpentane.

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

Explanation:

Answer:

F= m x a

force = mass x acceleration

Explanation:

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.

Answer: They have eight outer electrons.

Explanation: They don't need any more electrons to be added to them and can't give out any electrons to other groups. They have a complete outer shell.

Answer:

See explanation

Explanation:

The p orbital is threefold degenerate. This implies that the p-sublevel is composed of three orbitals; px, py and pz.

According to Hund's rule, electrons occur singly when filling degenerate orbitals before pairing takes place. Since the three orbitals are degenerate, any of px, py or pz may be first filled.

If one lobe of any of the px, py or pz is first filled, the next electron must go into the next degenerate orbital. When all are filled, pairing of electron spins may now begin.

Based on Hund's rule the electron is most like to be found in Px, Py or Pz, and it will fill them singly before paring.

The P-orbital has three sub-orbitals or degenerate orbitals such as Px, Py and Pz which an electron occupy at a time before paring.

The maximum electron in P-orbital is 6 electrons, each degenerate orbital will contain maximum of 2 electrons.

According to Hund's rule, electron will fill the degenerate or sub-orbitals singly first before paring.

Thus, we can conclude that based on Hund's rule the electron is most like to be found in Px, Py or Pz, and it will fill them singly before paring.

Answer:

Savanna regions have two distinct seasons - a wet season and a dry season. There is very little rain in the dry season. In the wet season vegetation grows, including lush green grasses and wooded areas.

Savannas are grasslands found in Africa, Australia, South America, and India. The climate is warm or hot. Savannas experience both dry and rainy seasons. Each year, savannas receive about 20 to 50 inches of rain in a span of six to eight months. The other months are dryer. There’s also a threat of wildfires because of the severe dryness during these months. Grasslands are true to their name because their vegetation is mostly grass. Savannas are home to a wide range of animals, including different species of beetles and insects, which many creatures consume. Squirrels, mice, elephants, gazelles, and antelopes are the plant-eating animals that live in the savanna. Hyenas, lions, and leopards are some of the meat-eating animals in these areas. Some of the nonliving components of the system include very porous soil that allows water to drain easily.

Gas law: Combined law, P1 value: 1.82 atm, P2 value: 2.35 atm, T1 value: 293 K, T2 value: 380 K, Kelvin temperature when pressure is increased: 380 K.

The combined gas law is a gas law that combines Boyle's law, Charles's law, and Gay-Lussac's law into one equation. It relates the pressure, volume, and temperature of a fixed amount of gas.

To solve this problem, we will use the combined gas law:

(P1 * V1)/T1 = (P2 * V2)/T2

where P1 is the initial pressure, V1 is the initial volume (constant), T1 is the initial temperature, P2 is the final pressure, V2 is the final volume (constant), and T2 is the final temperature (what we need to find).

The value for V1 and V2 are constant and are not given in the problem statement, but we can assume they are the same since the amount of gas and volume are constant.

Therefore, we can simplify the equation as:

P1/T1 = P2/T2

To find the value of T2, we can rearrange the equation as:

T2 = (P2 * T1)/P1

Now, let's plug in the given values:

P1 = 1.82 atm

T1 = 293 K

P2 = 2.35 atm

T2 = (2.35 * 293)/1.82

T2 = 380 K

Therefore, the gas in the tire will have a temperature of 380 K when the pressure is increased to 2.35 atm.

Answer: A, metals tend to have lower ionization energies than nonmetals

Explanation:

Got it right on the quiz

positron emission and electron capture both occur in specific radioactive decays and are associated with unstable nuclei. They play a crucial role in balancing the ratio of protons to neutrons in a nucleus, leading to more stable configurations.

Positrons and electrons are both subatomic particles with opposite charges. Positrons have a positive charge (+1), while electrons have a negative charge (-1). They have the same mass, which is approximately 9.1 x 10^-31 kilograms.

However, positrons and electrons differ in their origins. Positrons are the antiparticles of electrons, meaning they have the same mass but opposite charge. Positrons are typically produced in certain radioactive decays, while electrons are ubiquitous in atoms and play a fundamental role in chemical reactions.

Positron emission occurs when a proton inside an unstable nucleus is converted into a neutron, releasing a positron and a neutrino. This process reduces the atomic number by one while maintaining the mass number. The positron is ejected from the nucleus, carrying away the positive charge.

The positron can cause transmutations by colliding with an electron in the vicinity. The collision results in the annihilation of both particles, converting their masses into energy in the form of gamma rays. This annihilation process contributes to medical imaging techniques like PET scans.

Electron capture happens when an unstable nucleus captures an electron from its electron cloud. The captured electron combines with a proton in the nucleus, resulting in the formation of a neutron and a neutrino. This process also reduces the atomic number by one while preserving the mass number.

Electron capture causes transmutations by changing the composition of the nucleus. By capturing an electron, the number of protons decreases, transforming the element into another one with a lower atomic number.

Positron emissions and electron capture both result in the reduction of atomic number by one. However, positron emission involves the release of a positron from the nucleus, while electron capture involves the capture of an electron by the nucleus. The overall effect is the same—a decrease in atomic number.

Furthermore, positron emission and electron capture both occur in specific radioactive decays and are associated with unstable nuclei. They play a crucial role in balancing the ratio of protons to neutrons in a nucleus, leading to more stable configurations.
