Answer:
The answer to your question is Stoichiometry
Explanation:
Stoichiometry is a very important branch of inorganic chemistry that is used to calculate the amount of reactants or products necessary in a chemical reaction so we can get the highest yield.
In stoichiometry, we must know the balanced chemical reaction and we can work with the mass in grams or moles.
For the whole set of problems, always remember the Avogadro’s
number is 6.023*10^23 units per mole of a substance. Units could be atoms,
molecules or formula units.
The first question asks for the number of molecules of NaNO3.
The molar mass of NaNO3 is 85 grams per mole. So,
<span>150g NaNO3(1mole NaNO3/85 grams NaNO3)(6.023*10^23
molecules/1mole NaNO3)=1.063*10^24 molecules of NaNO3</span>
<span>5.7*10^46 molecules of NaNO3(1mole NaNO3/6.023*10^23
molecules)(85 grams NaNO3/1mole NaNO3) = 8.044*10^24 grams NaNO3</span>
For the molar mass of water, we have 18.02grams per mole.
301 moles H2O(18.02 grams H2O/1
mole H2O) = 5424.02 grams H2O
For the molar mass of sulfuric
acid, we have 98.08 grams per mole.
25g H2SO4(I mole H2SO4/98.08g H2SO4) =
0.2549 mole H2SO4
For the molar mass of Ca(OH)2,
we have 74.1 grams per mole.
252gCa(OH)2(1mol/74.1g)(6.023*10^23/1mol)
= 2.048*10^24 molecules of Ca(OH)2
For the molar mass of calcium,
we have 40 grams of Ca per mole.
6.7*10^35 atoms Ca(1 mole
Ca/6.023*10^23 atoms)(40g Ca/1mol Ca) = <span>4.45*10^13 grams Ca</span>
The "molecule a" referred to ATP in the equation.
So, option A is correct one.
The equation is given as,
→ 
The above equation indicates the respiration activities in the plants.
The aerobic respiration takes place in the Mitochondria and which requires oxygen and glucose and produces carbon dioxide , water and energy.
The energy is in the form of ATP. The pull form of ATP is adenosine triphosphate. The ATP is also called energy carrier because it found in the cells of the all living organism and this molecule carries energy.
