Answer: Bacteria, some insects, and fungal species are the decomposers of the dead and decaying matter.
Explanation:
The decomposers are the organisms which act and feed on the dead and decaying organic matter so as to obtain energy from it and degrade it to the simple forms that can be utilized by the plants. Bacteria, some insects and fungi that live in the soil and on the decaying matter. The fungi for example decay on the lignin present in the wood so helps in wood decomposition of trees. If the decomposer like fungi are absent the wood mass will not decompose and it will remain as waste and can be used by the plants in the form of nutrients.

what are particles that differ in number between isotopes
Answer:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?
Answer:
1 mole is equal to 1 moles NaOH, or 39.99711 grams.
Explanation:
Hope this helps have a nice day :)
The statement of the mass of sodium hydroxide (NaOH) is "130 g."
What is mass?A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.
In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.
Mole to gram conversion factor,
[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]
Mass of NaOH comes out to be,
[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]
= 129.99 g
= 130 g
Hence the correct answer is 130 g.

How many valence electrons are there in Se atom?
Answer:
4 valence electrons
Despite the fact that the word silicon has a ubiquitous affiliation with all things electronic, Si itself is not a good electrical conductor. It has 4 valence electrons, meaning that filling its outer shell it can form a very strong lattice with 4 neighboring Si atoms-with no un-bonded electrons remaining
Answer:
The numer of valence electrons is defined as the number of electrons present in the outer most shell of the atom.So, in the case if selenium, there are 6.
Which radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time?
Pu-239
FR-229
Fe-53
P-32
Answer:pu-239
Explanation:
Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time
Disposal of radioactive nuclear waste is often regarded as a problem.
The waste sources are:
Nuclear power reactors Bomb-related nuclear materialDisposal of bomb-grade plutonium is often difficult.
The longer lived isotopes are:
Plutonium-239 whose t1/2 is 24,110 years, Plutonium-240 whose t1/2 is 6,540 years, Curium-245 whose t1/2 is 8,500 years. etc.The storage of the longer lived elements is through containment for the next several thousand of years.
