How many Moles of glucose are produced from 12 moles of CO2 in photosynthesis?
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.

ssignment (1) Nitrobenzene has a dipole moment of 4.2 x 10-9 esu cm while phenol has a value of only 1.7 x 10-8 esu cm. However, nitrobenzene is soluble only to the extent of 0.0155mole/kg in water while phenol is soluble to the extent of 0.95mole/kgat 20C. explain this phenomenon.
Phenol can form hydrogen bonds with water since it contains O-H group but nitrobenzene can not form hydrogen bonds with water.
Polar molecules tend to be soluble in water. The greater the dipole moment, the greater the polarity of the compound. We can see that Nitrobenzene has a dipole moment of 4.2 x 10-9 esu cm while phenol has a dipole moment of 1.7 x 10-8 esu cm.
Now, It is confusing to observe that the solubility of Nitrobenzene in water is far less than that of phenol despite its higher dipole moment. The reason for this observation is that, phenol can form hydrogen bonds with water since it contains O-H group but nitrobenzene can not form hydrogen bonds with water.
Therefore, phenol is more soluble in pure water as a solvent compared to nitorbenzene.

Which of the following two combinations are correct?
Answer:
D
Explanation:
Copper has a more positive reduction potential than Hydrogen and is below Hydrogen in the reactivity series. So it can't displace H+ from diluted acids. Therefore Cu doesn't form Cu salt and a gas
Fe, Zn and Mg are above Hydrogen in the electrochemical series and can displace Hydrogen as follows
Fe(s) + 2HCl(aq) ----> FeCl2 +H2 (g)
Mg(s) + 2HCl(aq) ----> MgCl2 (aq) +H2 (g)
So iii is wrong
Zn(s) +2HCl(aq) ----> ZnCl2(aq) +H2 (g)

A. C6H1206(s) + O2(g) → H2O(1) + CO2(9)
B. C6H1206(s) + 602(9) — 6H20() + 6C02(9)
C. CH2O(s) + O2(g) → H20(1) + CO2(9)
D. CH1206(s) + O2(g) – 12H20(1) + 6C02(9)

B. C6H1206(s) + 602(9) → 6H20(l) + 6C02(9)
Explanation:
You can see that it's balanced;
C6H1206(s) + 602(g) → 6H20(l) + 6C02(g)
C ⇒ 6 C ⇒ 6
H ⇒ 12 H ⇒ 6 x 2 = 12
O ⇒ 6 + (6 x 2) = 18 O ⇒ 6 + (6 x 2) = 18

Indicate how CaCO3 neutralizes soil acidity. In other words, indicate how calcium carbonate chemically removes hydrogen from soil solution.
Answer:
Soil acidity can be corrected easily by liming the soil, or adding basic materials to neutralize the acid present. ... As lime dissolves in the soil, calcium (Ca) moves to the surface of soil particles, replacing the acidity. The acidity reacts with the carbonate (CO3) to form carbon dioxide (CO2) and water (H2O).

In which substance are the electrostatic forces between molecules the strongest?
(1 point)
- propane
- turpentine
- glycerin
- acetone
The electrostatic forces between molecules of glycerin are the strongest.
We have 4 compounds with their respective boiling points.
acetone 56 °C turpentine 160 °C propane -43 °C glycerin 290 °CThe boiling point is the temperature at which a substance passes from the liquid state to the gaseous state.
A high boiling point indicates that the intermolecular forces are strong, so more energy is needed to separate the molecules in the vaporization.
Thus, glycerin, with the highest boiling point, is expected to have the strongest electrostatic forces between their molecules.
The electrostatic forces between molecules of glycerin are the strongest.

Explanation:
Hydrogen fusion creates _____ and lots of energy.
Explanation:
Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides extremely long confinement times that reach the conditions needed for fusion energy production. Proposed fusion reactors generally use hydrogen isotopes such as deuterium and tritium (and especially a mixture of the two), which react more easily than hydrogen to allow them to reach the Lawson criterion requirements with less extreme conditions. Most designs aim to heat their fuel to around 100 million degrees, which presents a major challenge in producing a successful design.
As a source of power, nuclear fusion is expected to have many advantages over fission. These include reduced radioactivity in operation and little high-level nuclear waste, ample fuel supplies, and increased safety. However, the necessary combination of temperature, pressure, and duration has proven to be difficult to produce in a practical and economical manner. Research into fusion reactors began in the 1940s, but to date, no design has produced more fusion power output than the electrical power input.[1] A second issue that affects common reactions is managing neutrons that are released during the reaction, which over time degrade many common materials used within the reaction chamber.
Fusion researchers have investigated various confinement concepts. The early emphasis was on three main systems: z-pinch, stellarator, and magnetic mirror. The current leading designs are the tokamak and inertial confinement (ICF) by laser. Both designs are under research at very large scales, most notably the ITER tokamak in
Diamond has a macromolecular structure and iodine is a simple covalent molecule. Use your knowledge of structure and bonding to explain why diamond has a higher melting point than iodine.
Answer:
Diamond is covalently bonded and has a giant covalent structure. Covalent bonds require lots of energy to break as they are strong so diamond has the highest melting point. Iodine has only weak intermolecular forces (instantaneous dipole-dipole interactions or London forces) whereas hydrogen fluoride has a permanent dipole and can hydrogen bond (as well as having London forces).

Answer:
i k ow its not the exact anwser but ih ope this helps
Explanation:
Energy plays a key role in chemical processes. According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy required to break bonds is larger than the energy evolved on making new bonds, and the net result is the absorption of energy. Such a reaction is said to be endothermic if the energy is in the form of heat. The opposite of endothermic is exothermic; in an exothermic reaction, energy as heat is evolved. The more general terms exoergic (energy evolved) and endoergic (energy required) are used when forms of energy other than heat are involved.
A great many common reactions are exothermic. The formation of compounds from the constituent elements is almost always exothermic. Formation of water from molecular hydrogen and oxygen and the formation of a metal oxide such as calcium oxide (CaO) from calcium metal and oxygen gas are examples. Among widely recognizable exothermic reactions is the combustion of fuels (such as the reaction of methane with oxygen mentioned previously).
