You have two pure substances that you cannot identify each sample is solid at room temperature describe at least five steps in the appropriate sequence that you would take to be able to identify the substances
Answer:
Explanation:
If we have two solid samples, in order to identify what they are a series of ordered steps have to be performed.
1) The first thing to do is to observe the sample. If there is color it may indicate the presence of certain anions: for example if the sample is purple, it can be because of the presence of the permanganate ion (MnO₄⁻), if it is yellow it can be chromate ion (CrO₄⁻), if it is orange it can be the dichromate Cr₂O₇²⁻), etcetera. If the color of the sample is white we have no indication whatsoever.
2) Then we can use certain reactants to precipitate the cations of the sample. For example, we can add first HCN 3N to our sample. If there is precipitation, it means that the cations Ag⁺ or Pb²⁺ are present. If not, there are other cations and we must use a different reactant to precipitate them.
3) We then add H₂S to the sample (not adding it per se, but generating it heating thioacetamide with water). If we see a black precipitate, it can be because of the cations Pb²⁺, Bi³⁺ or Cu²⁺. If we see a yellow precipitate, it corresponds to Cd²⁺. If we do not see a precipitate, we need to add other reactant.
4) We add NaOH to the sample. If we see precipitate, it can be because of the the ions Fe³⁺, Ni²⁺, Co²⁺ or Mn²⁺.
5) We observe the color of this precipitate. If it is brown is Fe(OH)₃, if it is green is Ni(OH)₂, if it is pink is Co(OH)₂, and if it is white is Mn(OH)₂.
Se toma la muestra problema o alícuota y se añade HCl 2N. Con este reactivo precipitan los cationes del Grupo I ( Plata (I), Plomo (II) y Mercurio (I)): AgCl, PbCl2 y Hg2Cl2. Sobre el mismo embudo se añade agua de ebullición, quedando en el papel de filtro el AgCl y el Hg2Cl2; el Pb2+ puede identificar añadiendo KI, que origina un precipitado de PbI2 que se disuelve en caliente, que sirve para identificarlo mediante la llamada lluvia de oro.1
Sobre el mismo papel de filtro se añade NH3 2N. En el papel de filtro si existe Hg22+ y se forma una mancha blanca, gris o negro, que es una mezcla de HgClNH2 y Hg0. En la disolución se forman Ag(NH3)2+, que se puede identificar con KI dando un precipitado de AgI amarillo claro.

What do you know about deserts, grasslands, or tundra biomes?
Answer:
this is what i do when i bored :P
Explanation:
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sámi word тӯндар meaning "uplands", "treeless mountain tract".

Can you explain the atomic reactions that occur in nuclear fusion?
Can you explain what a photon is and how it is made?
How does this impact life on Earth?
Answer:
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.
The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum,
photons are in light so yeah

Which of the following is not a natural cause of extinction?
a.competition due to overpopulation
b.introduction of non-native species
c.catastrophic events
d.disease
Answer:
Introduction of Non-native species would be the answer. ( B )
Explanation:
Now let's break it down.
A. Competition due to overpopulation
Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.
B. Introduction of Non- native species.
So what does it mean by Non-native species?
It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.
C. Catastrophic Events
Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.
D. Disease
This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.
So, the Answer would be B.
HOPE THIS ANSWER HELPED :)Among the given options, the one that is a natural cause of extinction would be:
b). Introduction of non-native species.
'Non-native species' are described as the species that are introduced to an ecosystem different from its native habitat.
These species are severe threat to the existing ecosystem of the new habitat including plants, animals, aquatic life, etc. where they've been shifted.
Thus, it is not a natural cause as these species are not naturally introduced but the humans introduce them.
They turn so dominating to get their food and other things that it lead not only harmful but also lead to the extinction of the native species.
Hence, option b is the correct answer.

which of the following happens to a cell in hypotonic solution
A- The cell gains water and expands
B- The cell stays the same
C- The cell loses water and shrivels
D- Water moves out of the cell
Answer:
In a hypotonic solution, the solute concentration is lower than inside the cell. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies
Hypotonic solutions have lower solute concentrations than cells. If water keeps entering the cell, it can strain the membrane until the cell bursts and dies. Therefore, option (A) is correct.
What is hypotonic solution?In comparison to another solution, a hypotonic solution will have a lower solute concentration because of its composition. Without another solution to compare it to, it is impossible to determine whether a solution is hypotonic, isotonic, or hypertonic. A solution is said to be hypotonic when it has a relatively low concentration of solutes in comparison to another solution.
As a consequence of this, the solute concentration is lower in a hypotonic solution than it is inside of the cell. If the water continues to enter the cell, it has the potential to stretch the cell membrane to the point where the cell lyses and dies as a result of the rupture.

John lives on a part of Earth where the angle of the sun's rays are very high, and the latitude is low. Which temperatures
does John experience quite often? (1 point)
A. high temperatures
B. moderate temperatures
C. low temperatures
D. temperatures that are sometimes very high and sometimes low
Answer:
The correct option is A
Explanation:
Since the angle of the sun rays are high where John lives, it shows his area is exposed to high radiation of sunlight which is a pointer to high temperature. The question also says his area's latitude is low. Low latitude are those areas close to the equator whose areas are typically warmer than those who live close to the poles. Hence, it can be said that John often experiences high temperature based on the description above.
John often experiences high temperatures (Option A).
The angle of solar radiation is directly associated with the temperature and the localization on the Earth.In regions of low latitude near to the Equator, the angle of the solar radiation is nearly perpendicular or closer to a 90˚ angle and temperatures are warmer.Conversely, in regions of high latitude and near the poles, the angle of solar radiation is smaller and temperatures are colder.In conclusion, John often experiences high temperatures (Option A).

what are two organisms in the food web that have a predator-prey relationship? i need examples
Answer:
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
What do you mean by predator-prey relationship?In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.
Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.
The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.
