For this discussion, respond to the following... An electron falls through a distance d in a uniform electric field of magnitude
mars1129 [50]

The electron should experience a greater acceleration due to it's significantly smaller mass and should fall through distance "d" in a shorter amount of time.

<u>Explanation:</u>

The electron force can be expressed as F=qE. According to Newton's second law of motion force can be expressed as F=ma. This can be written as a=F/m. Substituting electric force expression for "F" in this equation, we get a=qE/m. This means acceleration is conversely proportional to mass and directly to electric field and charge. This means that proton having significantly larger mass than electron should experience smaller amount of acceleration and would take longer to fall at distance "d".

On the other hand, the electron would experience greater acceleration due to it's significantly smaller mass and would fall faster at distance "d", unlike the situation of proton.

What is bonding all about in chemistry?
Alina [70]
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

Kilauea volcano in hawaii emits 200-300 tons of sulfur dioxide into the atmosphere each day. this is an example of?
o-na [289]

Kilauea volcano in Hawaii emits 200-300 tons of sulfur dioxide into the atmosphere each day. This is an example of

  • the impact of natural processes on the earth's environment.
  • air pollution from a natural source.
  • the magnitude of the chemistry associated with the environment.

Kilauea volcano in Hawaii emits noxious compounds of sulfur dioxide and other harmful pollutants as a result of a reaction with atmospheric water vapors and oxygen.

This reaction results in acid rain and volcanic smog which pollutes the air.

Over the years, the volcano has become a potential threat to health as harmful oxides are accelerating respiratory problems and acid rain destroys crops, and also harms water supplies.

What is the enthalpy of formation (?H?f) of NaHCO3(s) from its constituent elements.
vova2212 [387]

Answer:

Enthalpy of formation = -947.68KJ/mol

Explanation:

Enthalpy of formation is the heat change when one mole of a substance is formed from its element in its standard states and in standard conditions of temperature and pressure. it may be positive or negative, if positive, it is an endothermic reaction where the heat content of the product is greater than that of the reactants, and if negative, it is exothermic reaction - where the heat content of the reactants is greater than the products. the enthalpy of formation is measured in KiloJoule/Moles (KJ/Mole).

From the value of the enthalpy of formation of NaHCO3, it shows that the reaction is exothermic, that is the formation of NaHCO3 from its constituents elements. As such, the heat content of the reactants is greater than the products.

The step by step explanation is shown in the attachment.
