Answer:
pls mark as brainliest!!!!!!
Explanation:
If you considering in smaller scale You can simply say that “There is One Hydrogen atom Binds with Cl atom”. But when we are using this chemicals in Labs.
We talking in Moles
Mole is a quantity defining unit. Which is larger than you couldn't Imagine. 1 mole of pebbles can covered whole surface of earth.
1Mole=6.022×1023
It means 1 mole of Hydrogen is containing 6.022×1023 atoms. Be aware “Be aware thats a Quantity defining factor” Then we can get actual ratio of chemical formula..
HCL “The chemical formula”
H : 1 “Above chemical formula containing 1 atom to binds with another species”
Cl : 1 “Clorin also same as Hydrogen”
Then, You can multiply Ratio of atom by Avagadro Constant which is we pre defined as 1 Mole.
For understand it simply This statement would be helpful.
1 mole containing, Avagadro number of atoms
Hope This would be helpful!
Answer:
the answer is going to be 3 because it asked how many atoms of hydrogen it never said how many number of atoms of hydrogen.
so,
HCl has 1 atom of hydrogen in ONE MOLE but there are 3 moles given so you multiply the atoms of hydrogen by 3 that is going to be your answer i.e. 3

What occurs along a convergent plate boundary?
Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

Type several paragraphs describing how a model could show effects of the rotation of Earth on day and night and the effects tilt. (4-5 paragraphs)
Answer:
The cycle of seasons is caused by Earth's tilt toward the Sun. Earth makes a complete orbit around the Sun every 365.25 days. It spins on an invisible axis that is tilted at an angle of 23.5°. The angle does not change; only the direction of the axis in relation to the Sun changes.
The north end of the axis points away from the Sun for half of year and toward the Sun for the other half. Depending on the time of year, some parts of Earth are tilted more toward the direct rays of the Sun than other parts. Parts of Earth that get more direct rays get warmer, and parts that get fewer direct rays are cooler. The difference in the amount of heat and light available at Earth’s surface determines the seasons.
Seasons vary from one part of the world to another. At different times during the year, the Northern or Southern Hemisphere is closer to the Sun. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere. Both hemispheres get similar amounts of energy from the Sun during fall and spring.
Rotation is the movement of the earth on its axis that causes day and night. The tilt of the planet is responsible for the season and the climatic changes.
What is rotation?Rotation is the movement of the planet on the axis in twenty-four hours that results in the day and night of the planet. The spinning of the planet in a counterclockwise direction results as if the sun rising and falling.
The tilt of the planet is due to revolution and the results in different seasons around the earth in one year or 365 days. The angle of the earth facing the sun plays a role in determining the season of the region.
Therefore, rotation determines day and night, while revolution determines the seasons.

Explanation: It is the tea cup because when you touch a tea cup, the energy is going into your hand. Your hand gets hot. That is thermal energy.
Answer:
i would say the tub
Explanation:
i dont have one cause it just depends on what is in the tub
Explain a situation where two different species could compete for the same abiotic resource. I really can't figure this out
Resource partition in which two species compete with themselves for same abiotic resource, they avoid competition by choosing different times for feeding.
What are the Abiotic resources?The abiotic resources are defined as the non-living element present surrounding the ecosystem, for example Sunlight, water and soil; Abiotic factors can be chemical and physical factors which include the atmosphere, the hydrosphere, and the lithosphere.
The abiotic resource include Climate is the weather conditions and temperature and plays an important role in maintaining ecosystems, even a small change in climate can change the organism life.
pH balance is the resource refers to the overall acidity or alkalinity level of the environment, for example Pure water has a pH of 7, Acidic mixtures have a pH balance of less than 7 and alkaline mixtures have a pH balance of 7 or more which shows its effects on the organism.
Light is present in an environment or ecosystem can have an impact on the organisms of the ecosystem.
Water Currents play a crucial role in regulating ecosystems which is the most important and beneficial parts of the marine ecosystem and they are important because they redistribute minerals, nutrients, heat, oxygen, and more.

_____________ stated that electrons orbit the nucleus. Question 1 options:
Bohr
Thomas
Rutherford
Democritus
Answer:
I believe it would be Bohr
Explanation:
Answer:
Bohr
Explanation: a theory of atomic structure in which the hydrogen atom (Bohr atom ) is assumed to consist of a proton as nucleus, with a single electron moving in distinct circular orbits around it, each orbit corresponding to a specific quantized energy state: the theory was extended to other atoms.
Therefor, the answer is Bohr. hopefully this helped!
