Explanation:
be it’s a Chemical change not a physical change
Two liquids when combined to form a solid substance is an example of chemical change as rearrangement of atoms takes place in the process.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

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.

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.

How many Hydrogen atoms are present in this chemical equation: 3HCl
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

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.

The formula for calculating density, D, is D=M/V, where M represents mass and V represents volume.
For liquids, volume is often given in cubic centimeters (cc), which is the same as cm 3. If the density of an unknown liquid is 1.6 g/cc, what is the mass of 800 cc of the unknown liquid in grams (g)?
0.002 g
1.6 g
500 g
1280 g
Answer:
The answer is; D
Explanation:
Density 1.6g/cc means that every 1(one) cubic centimeter of the liquid has a mass of 1.6 grams.
Then, what about 800 cubic centimeters – how much mass, in grams, will it have ?
= 1.6 * 800 = 1280 g
What is the self-feeders for Paramecia?
Write your response below
Answer:
Paramecium (also Paramoecium, is a genus of unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds. Because some species are readily cultivated and easily induced to conjugate and divide, it has been widely used in classrooms and laboratories to study biological processes. Its usefulness as a model organism has caused one ciliate researcher to characterize it as the "white rat" of the phylum Ciliophora.

Which element(s) is/are not balanced in this equation?
Which best explains why metal cooking utensils often have a plastic coating on their handles? Plastic melts less easily and lasts longer than metal. Plastic reduces the transfer of thermal energy to hands holding the utensils. Plastic molds more easily into shapes like long, thin handles. Plastic increases the rate of conduction from the utensil to the food.
answer quickly, please
Metal cooking utensils often have a plastic coating on their handles because it reduces the transfer of thermal energy to the hands holding the utensils. Therefore, option (B) is correct.
What is thermal energy?Thermal energy can be produced in a substance when an increase in temperature causes atoms to move at a higher speed and result they collide with each other. The energy generated from the temperature of the heated material is called thermal energy.
Thermal Energy is due to the random motion of molecules in a system and is directly proportional to the temperature. The greater the temperature the greater the movement of molecules and the greater the thermal energy of the system.
The thermal conductivity of metal does show a variation with an increase in temperature. As metal utensils have high conductivity for thermal energy therefore plastic handles are used to prevent the transfer the thermal energy.
