Answer:
pioneer species, soil formation, plant growth
Explanation:
The events of succession after a volcano erupted in the proper order include pioneer species being visible. The pioneer species such as algae and Moss are usually found on rocks and dead matter.
After sometime the soil starts to form through weathering activities which then gives rise to and supports the growing of plant species.

hey guys can u help me ASAP its on science
Answer:
The answer to your question is A - electrons
Explanation:
To be honest it's pretty obvious, none of the other things could possibly come with valence behind it so electrons is the only logical answer.
Answer:
A. electrons
Explanation:
The valence electrons on the valence shell which is the last layer of electrons are the same for atoms in the same column.
What is atomic mass made of?
Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
Explanation:
scientist have grouped the number of elements into
Answer:
columns and rows on the periodic table and groups based on reactivity and such like halogens,noble gases, trans metals, alkali metals, alkaline earth metals, lanthanids, actinids, metalliods, nonmetals and metals.

Which statement is true about molarity and percent by mass? (3 points)
Molarity is the amount of solute in 1L of solution while percent by mass is the ratio of the mass solute to the mass of solution multiplied by 100. Both quantities are used measure the amount of solute in solution.
What is molarity and percent by mass?The question is incomplete however, I will try to explain molarity and percent by mass.
The term molarity means the number of moles of a substance is 1 L of solution while the percent by mass is the ratio of the mass solute to the mass of solution multiplied by 100.
Both molarity and percent by mass shows the amount of solute in a solution.

How would adding the catalyst nitrogen monoxide (NO) affect this reaction?
2SO2(g) + O2(g) → 2SO3(g)
A) NO increases the rate at which SO3 molecules are formed.
B) NO reacts with SO3 to produce more SO2 molecules.
C) NO decreases collisions between the SO2 and O2 molecules.
D) NO increases the concentration of the SO2 and O2 molecules.
E) NO increases the activation energy of the SO2 and O2 molecules.
Answer: A) NO increases the rate at which [tex]SO_3[/tex] molecules are formed.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more reactant molecules can cross the energy barrier by undergoing collisions and convert to products.
[tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]
Thus NO will increase the rate of reaction by lowering the activation energy and thus the colllisions among [tex]SO_2[/tex] and [tex]O_2[/tex] molecules will incraese which in turn will lead to formatioon of more [tex]SO_3[/tex] molecules.
Answer:
A) NO increases the rate at which molecules are formed.

Match the intermolecular force with the physical property that will result
Answer:
Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase. Hope this is what your looking for!

What type of reaction will occur with the following reactants?
CaS + NaCl -->
A) double replacement
B) decomposition
C) synthesis
D) single replacement
Answer:
A) double replacement
Explanation:
Chemical equation:
NaCl +CaS → Na₂S + CaCl₂
Balanced chemical equation:
2NaCl +CaS → Na₂S + CaCl₂
The given reaction is double replacement reaction in which cation and anions of each reactant exchange with each other.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
Other options are incorrect because,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
AB → A + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Balance this equation pls
__NaCl + __CaF2→ __NaF +__CaCl2
Answer:
2NaCl + 1CaF²--------》2NaF + 1CaCl²
Answer:
2NaCl + CaF2 >>> 2NaF + CaCl2

Bats have oversized ears, which help the bats use sound waves to detect the motion of their prey. Which example of the characteristics of life is most similar?
Answer:
option B = A rat hides in its hole when it sees an approaching predator.
Explanation:
In order for any organisms, whether plants or animals to be able to keep being alive they have to develop a/some functions or abilities which is going to aid in their battle battle for survival, this concept is known as the Adaptive features of organisms.
From the question above, it can be seen that the oversized ears in bats is an adaptive features for them to get their food: as it helps them to use sound waves to detect the motion of their prey.
Unlike the bats, the rats adaptive features is to have a good running legs. This will help them to avoid getting eating by predators.

What is depicted as the yellow arrows in the following image? (Using a scientific vocabulary word we learned in class and provide its definition) Which makes a bigger current- faster moving electrons or slower moving electrons?
Answer:
Electric Current
Explanation:
The yellow arrows in the following image depict electric current. Electric current is defined as the continuous flow of electrons in an electric circuit. Electrons present in the conducting material which move from one to another atom randomly from the negative terminal through the connecting wires and back to the positive terminal.
Faster moving electrons make a bigger current because faster moving electrons collide more with each other that generates more heat which results into a higher current.
Hence, The yellow arrows in the following image depict electric current and Faster moving electrons make a bigger current.
The yellow arrow in the diagram shows the flow of electrons.
Current is defined as the flow of electrons in a circuit. The yellow arrows represents the direction of the flow of electrons in the circuit. The battery provides the potential difference that drives the flow of electrons through the wire.
Since current has to do with the movement of electrons in a circuit, the faster the movement of the electrons, the bigger the current.
