Answer: Hewo there! your answer is Below

Soil bacteria perform recycling of soil organic matter through different processes, and as a result they produce and release into the soil inorganic molecules

Explanation:

Bacteria consume organic matter and other compounds and recycle them into substances that can be used by other organisms. Bacteria can live anywhere that has water. They are more numerous, can reproduce faster and can survive harsher conditions than any other organism on Earth.

Hope this helps you!!

Have a great day❤️❤️

Answer:

Explanation:

Protozoa and Bacteria: Protozoa are very small one-celled creatures. They play an important role in helping to make the soil better by feeding on bacteria and releasing excess nitrogen, which is really good for plants. Bacteria are among the tiniest and most numerous organisms in the soil.

How many grams of lead sulfide from when 10.0 g of lead are heated with 3.0 g of sulfur

zaharov [31]

The reaction forms 11.5 g PbS.

We have the masses of two reactants, so this is a limiting reactant problem.

We know that we will need a balanced equation with masses, moles, and molar masses of the compounds involved.

Step 1. Gather all the information in one place with molar masses above the formulas and everything else below them.

M_r: 207.2 32.06 239.28

Pb + S → PbS

Mass/g: 10.0 3.0

Step 2. Calculate the moles of each reactant

Moles of Pb = 10.0 g Pb × (1 mol Pb /207.2 g Pb) = 0.048 26 mol Pb

Moles of S = 30 g S × (1 mol S/32.06 g S) = 0.9357 mol S

Step 3. Identify the limiting reactant

Calculate the moles of PbS we can obtain from each reactant.

From Pb: Moles of PbS = 0.048 26 mol Pb × (1 mol PbS/1 mol Pb )

= 0.048 26 mol PbS

From S: Moles of S = 0.9357 mol S × (1 mol PbS/1 mol S) = 0.9357 mol PbS

Pb is the limiting reactant because it gives the smaller amount of PbS.

Step 4. Calculate the mass of PbS.

Mass = 0.048 26 mol PbS × (239.28 g PbS/1 mol PbS) = 11.5 g PbS

The reaction produces 11.5 g PbS.

Specific Heat Material Copper Aluminum Gold Pyrex Specific Heat (J/g °C) 0.385 0.902 0.129 0.75 Material Water Ice Olive Oil Air

zimovet [89]

Explanation:

It is known that the amount of heat necessary to raise the temperature of 1 gram of a substance by $1^{o}C$ is known as specific heat.

Since, q = $mC \Delta T$

So, larger is the specific heat of a substance less will be the change in its temperature.

Therefore, olive oil has less specific heat as compared to water. This means that olive oil would get hotter.

Similarly, the specific heat of gold is lesser than the given materials or metals. Hence, gold will requires less heat to rise its temperature.

As a result, water present in gold will heat readily.

As the relation between heat and specific heat is as follows.

q = $mC \Delta T$

Therefore, calculate the amount of heat required by the water as follows.

q = $mC \Delta T$

= $100 g \times 4.18 J/g^{o}C \times (100 - 20)^{o}C$

= 33440 J

or, = 33.44 kJ (as 1 kJ = 1000 J)

Thus, 33.44 kJ heat would it take to raise the temperature of 100.0 g of water from $20.0^{o}C$ to $100.0^{o}C$ .

How many energy levels does the element helium have?

Alex Ar [27]

Answer:

Element Helium have 2 energy levels.

Explanation:

HELIUM - With the symbol He and the atomic number 2, helium is a chemical element. It is a colorless , odorless, tasteless, non-toxic, inert, monatomic gas that is the first in the periodic table in the noble gas group. Of all the elements, its boiling point is the lowest.

At about 24 % of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined, it is present. In both the Sun and Jupiter, its abundance is identical to this. This is due to helium-4's very high nuclear binding energy (per nucleon) with respect to the next three elements following helium.

Hence , the answer is 2 energy levels in Helium atom.
