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.

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.

First Question:

Melting is a physical process that involves the phase transition of a substance from its solid to its liquid state. Burning, on the other hand, is a chemical process that involves a substance being broken down and changed into different substances. It's still the same substance, though: water.

Second Question:

Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction. But mass+energy is always conserved. Energy cannot be created out of anything.

Answer:

c>b=a

Explanation:

It is important to note that mass does not affect the average motion/energy per molecule, but temperature does. the higher the temperature the faster the particles are. A has the same temperature as B, so they have the same amount of motion. C is warmer than A and B, so the average motion of the particles in beaker C is the largest

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

Answer:

C8H12

Explanation:

First find the molar mass

195/1.8 × 1 = 108.3 gmol-1

Then the molecular formula

Mass of C in 1 mole of compound = 88.82×108.3/100

= 96.2 g

Mass of H in 1 mol of.the compound = 108.3×11.18/100 = 12.11 g

Divide the mass by their molar masses to get no. of moles in 108.3 g of compound or 1 mole of compound

Moles of C in one Mole of compound = 96.2g/12 gmol-1 = 8 mol

Moles of H in 1 mole of compound = 12.11g/1 gmol-1 =12 mol

Since we need the molecular formula it's C8H12

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).

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

Answer:

B

Explanation:

The answer is B. All hydrocarbons are nonpolar, they are insoluble in water and they are highly flammable. Now, not all hydrocarbons have high boiling and melting point. For example, methane (CH4) has a boiling point of something clode to -161°C, and that is low. The boiling point increases when the number of carbon atoms in a compound increases, and based on methane and this theory, not all hydrocarbond have a high boiling point. This makes option B be the correct answer.

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)
