What type of intermolecular force happens with a polar covalent molecule when dipoles are created due to un-equal sharing of ele

ctrons?
Physics

Semmy [17]4 years ago
5 0

Answer:

Dipole-dipole interaction force

Explanation:

When one of the constituent atom of the covalent bonding is at least 1.5 times more electronegative than the other atom sharing the electron in the covalent bond then the shared pair of electrons are shifted towards the more electronegative atom developing a partial negative charge on it and similarly develops an equal partial positive charge on the other atom involved in the covalent bond.

  • This happens in water molecules and the resulting dipole is the cause of hydrogen bonding between two molecules of water. Hydrogen bond also exists in (HF) hydrogen fluoride molecules.

Goryan [66]

Answer: The chemical energy of reactants is greater than the chemical energy of products.

Explanation: In the given reaction

C_2H_6\rightarrow C_2H_4 + H_2 +137 kJ

It can be seen that the energy has been released. Thus we can say that reactants have converted to products by release of energy. Thus energy of products is less as compared to energy of reactants as some of the energy has been released.

Based on all we know about the terrestrial worlds, what single factor appears to play the most important role in a terrestrial p
Archy [21]

Based on all we know about the terrestrial worlds, the  single factor appears to play the most important role in a terrestrial planet's geological destiny is size size of terrestrial planet .

According to the question

Terrestrial Planets:

They belongs to a class of planets that are like the earth

Geological destiny :

Geology is biological destiny: Whatever minerals land or are deposited in a place determine what or who can make a living there millions of years later

Based on all we know about the terrestrial worlds, what single factor appears to play the most important role in a terrestrial planet's geological destiny

i.e

The size of terrestrial planet is one of the factors to play the most important role in a terrestrial planet's geological destiny  

which determines how long the planet can retain internal heat, which drives geological activity because  Smaller worlds cool off faster and harden earlier .

Hence, Based on all we know about the terrestrial worlds, the  single factor appears to play the most important role in a terrestrial planet's geological destiny is size size of terrestrial planet .

Nine-year-old Dakoda realizes that the quantity of water in a glass remains the same, even when the water is poured into a diffe
Archy [21]

Answer:

Conservation

Explanation:

She has observation conservation because If the temperature of the liquids stays constant and the container is insulated and not heat or cool the liquid much would not change the density of the liquid very much so that it's original volume could remain constant.

The interesting thing is not that the child assumes the taller glass holds more liquid but that they fail to understand conservation: the fact that the water from one glass is going to be the same amount after being poured into any other container. It's as if they did not realize the water came from the same glass.

A battery produces less electrical energy than the total amount of chemical energy contained in its reactive substances. Which s
labwork [276]

Answer:

The energy conversion does not fully occur due to various energy losses.

Explanation:

There are many different types of batteries, but all have three basic components: positive electrode (cathode, or "positive terminal"), negative electrode (anode or "negative terminal"), and electrolyte.

Charging a battery forces ions from  cathode to  anode;  the battery reverses the flow. Over a period of time, this process wears out  cathode, which results in reduced capacity.

Also there can be heat loss inside the system as well which is produced by the conversion from chemical energy.

Hence the chemical energy does not fully convert to electrical energy.
