The results of photosynthesis are used by cellular respiration, and photosynthesis first uses the results of cellular respiration.
Enthalpy of photosynthesis and cellular respiration:In the mitochondria, cellular respiration combines oxygen and glucose to produce ATP, along with water and carbon dioxide. Sunlight energy is used during photosynthesis to create glucose and separate oxygen from carbon dioxide and water. Globally, the exchange of carbon dioxide and oxygen during photosynthesis or cellular respiration serves to maintain stable levels of oxygen and carbon dioxide in the atmosphere.
Cellular Respiration: [tex]C_6H_1_2O_6+ 6O_2[/tex] → [tex]6CO_2 + 6H_2O[/tex]
Because CO₂ and H₂O are less energetic than the reactants, most notably glucose, the reaction is exothermic and has a negative enthalpy (ΔH < 0). This also makes sense because breathing causes glucose to be converted to energy.
Photosynthesis: [tex]6CO_2 + 6H_2O[/tex]→ [tex]C_6H_1_2O_6+ 6O_2[/tex]
The enthalpy change for the photosynthesis reaction is +2814 kJ/mol.

Perform the following operationand express the answer inscientific notation.7.00x10^5 - 5.00x10^4
Taking into account the scientific notation, the result of the subtraction is 6.5×10⁵.
Scientific notationFirst, remember that scientific notation is a quick way to represent a number using powers of base ten.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Subtraction in scientific notationYou want to subtract two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is 5.
Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 5.00×10⁴=0.500×10⁵
Taking the quantities to the same exponent, all you have to do is subtract what was previously called the number "a". In this case:
7.00×10⁵ - 0.500×10⁵= (7.00- 0.500)×10⁵= 6.5×10⁵
Finally, the result of the subtraction is 6.5×10⁵.

A cylinder with a movable piston contains 2.00 g of helium, He , at room temperature. More helium was added to the cylinder and the volume was adjusted so that the gas pressure remained the same. How many grams of helium were added to the cylinder if the volume was changed from 2.00 L to 3.90 L
Heya....
Here's your answer.....
PV = nRT... R is a constant...
so PV/nT = constant...
P1V1 / n1T1 = P2V2 / n2T2...P is constant.T is constant.. so
V1 / n1 = V2 / n2
since n = mass / mw
V1 / (mass 1 / mw) = V2 / (mass 2 / mw)
and since molecular mass = constant
V1 / mass 1 = V2 / mass 2
mass 2 = V2 x mass 1 / V1 = 2.90L x 2.00 g / 2.00 L = 2.9 g
mass 2 - mass 1 = 2.90 g - 2.00 g = 0.90 g
ie.. 0.90 g of He was added.

While working in a pharmaceutical laboratory, you need to prepare 1.50 L of a 2.20-M NaCl solution. What mass of NaCl would be required to prepare this solution
193 grams of NaCl are needed to make 1.50 L of a 2.20-M NaCl solution.
Calculation of the mass of NaCl required:
The only thing we need to know is that a solution's molarity informs us of the exact amount of moles of solute that are contained in 1 L of a solution.
In this situation, a NaCl (sodium chloride) solution with a 2.20-M concentration will have 2.20 moles of the solute (sodium chloride) in every 1 L of the solution.

The pH of the solution is determined by the hydrogen ion concentration. The pH of the solution with 1.5 M ammonia and 0.50 M hydrochloric acid is 8.77.
What is pH?The potential of the hydrogen ion in the solution is called pH which determines the basicity and acidity of the solution.
Given,
The molar concentration of 500 mL ammonia = 1.5 M
The molar concentration of 500 mL hydrochloric acid = 0.50 M
Kb (NH₃) = 1. 8 x 10⁻⁵
First, pOH is calculated as,
pOH = pKb + log [NH₃][HCl]
= - log 1. 8 x 10⁻⁵ + log [1.5][0.50]
= - log 1. 8 x 10⁻⁵ + log [3]
= 4.744 + 0.477
= 5.221

Which best explains why the trend in noble gas boiling points increases down the group?.
The atoms become larger, the intermolecular forces between the atoms become stronger and more energy is needed to overcome these forces. Hence, the boiling point of noble gases increases down the group.
What are noble gases?
Group 18 of the modern periodic table consists of noble gases. Helium, neon, argon, krypton, xenon, and radon are noble gases. These gases are monoatomic and chemically inert under normal conditions and because of this they are also called inert gases. These gases are present in very small quantities in the atmosphere, and so they are also called rare gases.Trends in Physical Properties of Noble Gases:
Atomic Radii (Atomic size): As we move down the group from helium to radon the atomic size of Noble Gasses keeps on increasing. This is because when going down the group, the number of occupied shells with valence electrons increases.Boiling and Melting Points: As we move down the group, the boiling and melting point of the Noble Gasses increases due to the following reason:When moving down in the group, the atomic radius increases which results in the formation of a strong Van Der Waals force of attraction between the atoms.As to overcome the interatomic force of attraction which becomes stronger, it also requires more energy during melting and boiling.Density: All elements of group 18 have low densities. When going down the group, density increases as the atomic mass keeps on increasing.Ionization Energy: In the periodic table, As we move down the group the first ionization energy keeps on decreasing.Ionization Potential: When going down the group, the atomic radii increases which increases the attractive force and ultimately results in the increase of polarity and decrease in the ionization potential.
