URGENT : how do the electrostatic forces between electrons influence their orbital spin?

Answers


Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

Which of the following properties of an unknown substance would allow it to be classified as a pure substance ?
A- can be dissolved into a solution
B- has a definite composition throughout
C- combines easily with other substances
D- is made of a single element or compound

Answers

D because that’s the only one that makes sense

Pure substances typically only include one type of atom or molecule and are homogeneous in nature. The majority of these chemicals have a consistent or homogeneous makeup. Thus, option C is correct.

What is pure substance?

Elements are pure compounds that cannot be chemically broken down into less complex ones. Iron, gold, sulfur, oxygen, and oxygen are some well-known elements.

Because it cannot be converted into a more basic substance, an element is an example of a pure substance. Examples of pure substances include water, neon, and sodium chloride (NaCl) (table salt).

One element or a few related compounds make up pure substances. A kind of matter with a predictable chemical composition and physical properties is referred to as a chemical substance.

Homogeneous mixes are made up of two or more components or compounds that cannot be seen separately from one another.

Therefore, a single element or compound show properties of pure substance.

The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there were no rain? What would be the long-term effects on the plant if the drought continues? Explain your answer.

Answers

Answer:

When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.

Explanation:

The Arizona poppy is the summer herb of deserts of southwestern US and has pinnately compound leaves and large snowy flowers. This poppy appears in rainy seasons.  

Due to the drought like conditions and fast-changing climate the poppy plant has learnt to adapt to the harsh climate of Arizona and is able to carry out the process of photosynthesis.  In the case of long-term drought conditions, the process of photosynthesis slows down as plant will absorb more light. This leads to stunted growth and possible death of the plant.

2. What was the primary reason in the 1850's driving the curiosity of atoms?
1905-Einstein
1827-Brown

Answers

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.

yo someone please help meee The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.69 m on each side?

Answers

Mass=volume x density

Mass of the cube of silver is 3,449.34 kg

First find the volume of the cube in centimeters because the density is in centimeters:

0.69 * 100 = 69 centimeters

Volume = Side * Side * Side

= 0.69 x 0.69 x 0.69

= 328,509 cm³

The density of a material is calculated by the formula:

= Mass / Volume

As you have the density already and the volume, you can get the mass:

10.5 = Mass / 328,509

Mass = 10.5 * 328,509

= 3,449,344.50 grams

A kilogram is 1,000 grams so the mass in kg is:

= 3,449,344.50 / 1,000

= 3,449.3445 kilograms

A 20 kg curling stone is sliding is sliding in a positive direction at 4 m/s. A second curling stone is sliding at the same speed but in the opposite direction. What is the kinetic energy of the two stones?

Answers

Answer:

The kinetic energy of the two curling stones is 320 J

Explanation:

Given;

mass of the first curling stone, m₁ = 20 kg

velocity of the first curling stone, v₁ = 4 m/s

velocity of the second curling stone, v₂ = - 4m/s

assuming the second curling stone to have equal mass with the first stone = 20 kg

The kinetic energy of the first curling stone is given by;

K.E₁ = ¹/₂m₁v₁²

K.E₁ = ¹/₂(20)(4)²

K.E₁ = 160 J

The kinetic energy of the second stone is given by;

K.E₂ = ¹/₂m₂v₂²

K.E₂ = ¹/₂ (20) (-4)²

K.E₂ = 160 J

Thus, the kinetic energy of the two curling stones is given by;

K.E = K.E₁ + K.E₂

K.E = 160 J + 160 J

K.E = 320 J

Therefore, the kinetic energy of the two curling stones is 320 J

B. they slide past each other
C. they are packed very closely together
D.they cause the solid to have a definite volume and definite shape



I think it is d c and a I may be wrong☺️​

Answers

Answer:

Answers are C, D

Explanation:

Solid particles always stick together no matter what happens unless it is changing into a liquid. If you are talking about vibration for solid particles that only applies to thermal vibratio so not A. They do not slide past each other because they are packed very tightly together. They have a definite shape and volume because they stay together unless facing heat. Hopefully this helps you :)

pls mark brainlest ;)

The statements about the particles present in her model that are true;

C and D

They are packed very closely together ( C ) They cause the solid to have a definite volume and definite shape ( D )

Particles of solids are closely packed and this feature distinguishes a solid from other forms of matter ( liquid and gas ). Solids have a definite volume and shape due to their closely packed particles.

Vibration in solids occur when solids are under thermal pressure and from her skating activity, there was no form of thermal pressure therefore solids vibrating in place would not be included in her model.

Hence we can conclude that The statements about the particles present in her model that are true; they are packed very closely together and  They cause the solid to have a definite volume and definite shape

How do scientists determine the number of neutrons in an isotope of an atom? O They find the number of protons. 0 They add the number of electrons and protons. They divide the atomic mass by two. They subtract the atomic number from the atomic mass. ​

Answers

Answer:

The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.

The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.[2] It was coined by a Scottish doctor and writer Margaret Todd in 1913 in a suggestion to chemist Frederick Soddy.

The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.

For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.
