<h2> Interconversion of energy.</h2>

Explanation:

Carbon moves from plants and animals to soils in the form of cycle.
When we take in oxygen we release carbon dioxide gas $(CO_{2})$ into the atmosphere.
Animals and plants give carbon dioxide gas through the process called respiration and transpiration.
From fossil fuels carbon moves in the atmosphere.
The fuels like wood or coal when burned releases carbon dioxide into the atmosphere.
The Matter is conserved in the carbon cycle as carbon absorbs energy and then it releases the same amount of energy.
Carbon changes from one form to another, but the total amount of carbon remains the same.

Which form of asexual reproduction describes the process of a cell dividing to

stepan [7]

Answer:A

Explanation:Binary Fission, meaning ‘getting divided into half’ is a type of asexual reproduction where a single living cell grows twice its size and then splits to form two identical daughter cells, each carrying a copy of the parent cell’s genetic material. Examples of cells that use binary fission for division

In order for fission reactions to be successful, they must be self-perpetuating, meaning they must be able to keep themselves go

aleksandrvk [35]

Answer:

Option C is correct.

The minimum amount of material that is needed for a fission reaction to keep going is called the critical mass.

Explanation:

Nuclear fission is the term used to describe the breakdown of the nucleus of a parent isotope into daughter nuclei.

Normally, the initial energy supplied for nuclear fission is the energy to initiate the first breakdown of the first set of radioactive isotopes that breakdown. Once that happens, the energy released from the first breakdown is enough to drive further breakdown of numerous isotopas in a manner that leads to more energy generation.

But, for this to be able to be sustained and not fizzle out, a particular amount of radioactive material to undergo nuclear fission must be present. This particular amount is termed 'critical mass'

What mass of limestone (in kg) would be required to completely neutralize a 15.5 billion-liter lake that is 1.7×10^−5 M in H2SO4

Alinara [238K]

The complete balanced chemical reactions are:

<span>So we see that 1 mole of CaCO3 is needed for 2 moles of HNO3 and similarly to 1 mole of H2SO4.
</span>The number of moles can be calculated as the product of volume and molarity, so:

moles H2SO4 = 1.7×10^−5 M * (15.5 x 10^9 L) = 263,500 mol H2SO4

moles HNO3 = 8.9×10^−6 M * (15.5 x 10^9 L) = 137,950 mol HNO3

So the total moles of CaCO3 required is:

moles CaCO3 = 263,500 mol * 1 + 137,950 mol * (1/2)

moles CaCO3 = 332,475 mol

The molar mass of CaCO3 is 100.086 g/mol, so the mass is:

mass CaCO3 = 332,475 mol * 100.086 g/mol

mass CaCO3 = 33,276,092.85 g = 33.3 x 10^3 kg
