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.

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.

Explanation:

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).

Explanation:

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.

Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses”. Impulses rush along tiny fibres, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.

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).

The electrostatic forces between molecules of glycerin are the strongest.

We have 4 compounds with their respective boiling points.

The 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:

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

Answer:

HBr

Explanation:

HBr (Hydrogen Bromide) is a polar molecule because of the unequal electronegativities of Hydrogen and Bromine atoms. Bromine has a higher electronegativity than hydrogen due to which electron bonded pair gets attracted slightly more towards bromine atom making HBr a polar molecule and resulting in a net dipole moment.

Answer:

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
