Answer:
2 MOLES OF GLUCOSE
Explanation:
How many Moles of glucose are produced from 12 moles of CO2 in photosynthesis?
6CO2 +6H20-------------->C6H12O6 -+ 6O20
(IN THE PRESENCE OF CHLOROPHYLL AND UV FROM )
)
6 MOLES OF CO2 MAKE 1 MOLE OF GLUCOSE
12 MOLES THEN MAKE 2 MOLES OF GLUCOSE
In the photosynthesis process, plants can use 12 moles of carbon dioxide to form 2 moles of glucose.
What is photosynthesis?It is the process by which green plants and some other organisms convert light energy into chemical energy.
Let's consider the balanced equation for the synthesis of glucose through photosynthesis.
6 CO₂ + 6 H₂O ⇒ C₆H₁₂O₆ + 6 O₂
The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1. The moles of glucose formed from 12 moles of carbon dioxide are:
12 mol CO₂ (1 mol C₆H₁₂O₆/6 mol CO₂) = 2 mol C₆H₁₂O₆
In the photosynthesis process, plants can use 12 moles of carbon dioxide to form 2 moles of glucose.

(100 POINTS!!!!) In one to two sentences, describe the process by which the ionic compound, LiCl, would dissolve in the polar solvent, CH3COCH3
Answer:
LICL as an Ionic compounds has covalent ability and they are soluble in polar solvent such as CH3COCH3 but they are insoluble in non-polar solvents. Due to their polarity, CH3COCH3 will decreases the electrostatic forces of attraction thereby resulting in free ions in aqueous solution.
Water is the known as a polar solvent that can dissolve an ionic compounds very easy and as a polar solvent, the arrangement of oxygen and hydrogen atoms in water is in bent shape.
Ionic compounds like LICL that is very polar is soluble in the polar solvent water.
Polar solvents like CH3COCH3 will dissolve polar and ionic solutes because of the attraction of the opposite charges on the solvent and solute particles.

How many atoms can be found in a sample of 75g of silicon
Answer:
[tex]\boxed {\boxed {\sf 1.6 \times 10^{24} \ atoms \ Si}}[/tex]
Explanation:
We are asked to find how many atoms are in a sample of 75 grams of silicon.
1. Convert Grams to MolesFirst, we must convert grams to moles using the molar mass. This is the mass of 1 mole of a substance. The molar mass is found on the Periodic Table because it is equal to the atomic mass, but the units are grams per mole instead of atomic mass units.
Look up the molar mass of silicon.
Si: 28.085 g/molWe convert using dimensional analysis, so we must set up a conversion factor.
[tex]\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]
We are converting 75 grams of silicon to moles, so we multiply by this value.
[tex]75 \ g \ Si*\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]
Flip the conversion factor so the units of grams of silicon cancel.
[tex]75 \ g \ Si*\frac {1 \ mol \ Si}{28.085 \ g \ Si}[/tex]
[tex]75 *\frac {1 \ mol \ Si}{28.085 }[/tex]
[tex]\frac {75}{28.085} \ mol \ Si[/tex]
[tex]2.670464661 \ mol \ Si[/tex]
2. Convert Moles to AtomsNext, we convert moles to atoms using Avogadro's Number, or 6.022 ×10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this problem, the particles are atoms of silicon.
Set up another conversion factor, this time with Avogadro's Number.
[tex]\frac {6.022 \times 10^{23} \ atoms \ Si}{1 \ mol \ Si}[/tex]
Multiply by the number of moles we found.
[tex]2.670464661 \ mol \ Si*\frac {6.022 \times 10^{23} \ atoms \ Si}{1 \ mol \ Si}[/tex]
The units of moles of silicon cancel.
[tex]2.670464661 *\frac {6.022 \times 10^{23} \ atoms \ Si}{1 }[/tex]
[tex]2.670464661 * {6.022 \times 10^{23} \ atoms \ Si}[/tex]
[tex]1.60815382 \times 10^{24} \ atoms \ Si[/tex]
The original value of grams (75) has 2 significant figures, so our answer must have the same. For the number we found, that is the tenths place. The 0 in the hundredths place tells us to leave the 6 in the tenths place.

The partial pressure of CO2 gas in a bottle of carbonated water is 4.60 atm at 25 ºC. How much CO2 gas (in g) will be released from 1.1 L of the carbonated water when the partial pressure of CO2 is lowered to 1.28 atm? At 25 ºC, the Henry’s law constant for CO2 dissolved in water is 1.65 x 103 atm, and the density of water is 1.0 g/cm3.
If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.
The partial pressure of CO₂ gas in a bottle of carbonated water is 4.60 atm at 25 ºC. We can calculate the concentration of CO₂ using Henry's law.
[tex]C = k \times P = \frac{1.65 \times 10^{-3} M }{atm} \times 4.60 atm = 7.59 \times 10^{-3} M[/tex]
We can calculate the mass of CO₂ in 1.1 L considering its molar mass is 44.01 g/mol.
[tex]\frac{7.59 \times 10^{-3} mol}{L} \times 1.1 L \times \frac{44.01 g}{mol} = 0.367 g[/tex]
Now, we will repeat the same procedure for a partial pressure of 1.28 atm.
[tex]C = k \times P = \frac{1.65 \times 10^{-3} M }{atm} \times 1.28 atm = 2.11 \times 10^{-3} M[/tex]
[tex]\frac{2.11 \times 10^{-3} mol}{L} \times 1.1 L \times \frac{44.01 g}{mol} = 0.102 g[/tex]
The mass of CO₂ released will be equal to the difference in the masses at the different pressures.
[tex]m = 0.367 g - 0.102 g = 0.265 g[/tex]
If the partial pressure of CO₂ in a bottle of carbonated water decreases from 4.60 atm to 1.28 atm, the mass of CO₂ released is 0.265 g.

Suppose you are performing a precipitation titration to study the K sp of zinc(II) iodate, Z n ( I O 3 ) 2 . The literature value of K sp is 3.9 × 10 − 6 . If you use 0.200 M K I O 3 as the titrant, what concentration of I O 3 − (in M) do you predict will be needed to start precipitation in a 0.229 M solution of Z n ( N O 3 ) 2 ?
The predicted concentration of IO₃⁻ needed to start the precipitation titration is 1.703 × 10⁻⁷ M
The dissociation of zinc (II) iodate can be expressed as:
[tex]\mathbf{Zn (IO_3)_2 \to Zn^{2+} + 2IO_3^-}[/tex]
Given that the solubility product constant Ksp value = 3.9 × 10⁻⁶
For the above dissociation,
[tex]\mathbf{Ksp = [Zn^{2+ }] [IO_3^-]^2}[/tex]
Since [tex]\mathbf{ [Zn^{2+ }] = [Zn(NO_3)_2] = 0.229 \ M}[/tex]
∴
[tex]\mathbf{3.9\times 10^{-8} =(0.229) \times [IO_3^-]^2}[/tex]
[tex]\mathbf{ [IO_3^-]^2 = \dfrac{3.9\times 10^{-8} }{(0.229)}}[/tex]
[tex]\mathbf{ [IO_3^-]^2 = 1.703 \times 10^{-7} \ M}[/tex]
Therefore, we can conclude that the initial predicted concentration of IO₃⁻ needed to start the precipitation titration is 1.703 × 10⁻⁷ M

Under an O2(g) pressure of 1.00 atm, 28.31 mL of O2(g) dissolves in 1.00 L H2O at 25 °C. What will be the molarity of O2 in the saturated solution at 25 °C when the O2 pressure is 4.47 atm? Assume that the solution volume remains at 1.00 L.
In the first case, the molarity of oxygen gas is 0.0012 mol/L. In the second case, the molarity of oxygen gas is 0.0052 mol/L .
We have to obtain the number of moles of oxygen as follows;
P = 1.00 atm
V = 28.31 mL or 0.02831 L
n = ?
R = 0.082 atm LK-1mol-1
T = 25 °C + 273 = 298 K
n = PV/RT
n= 1.00 atm × 0.02831 L/ 0.082 atm LK-1mol-1 × 298 K
n = 0.0012 moles
Molarity = Number of moles/Volume = 0.0012 moles/1.00 L = 0.0012 mol/L
For the second case;
P = 4.47 atm
V = 28.31 mL or 0.02831 L
n = ?
R = 0.082 atm LK-1mol-1
T = 25 °C + 273 = 298 K
n = PV/RT
n = 4.47 atm × 0.02831 L/0.082 atm LK-1mol-1 × 298 K
n = 0.1265/24.436
n = 0.0052 moles
Molarity of oxygen = 0.0052 moles/1.00 L = 0.0052 mol/L
