Answer:

When electrons are removed from an object, it becomes positively charged

Hatshy [7]3 years ago

An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.

1. Yes because the ocean takes in the carbon dioxide from the air. This causes more acid in the water, this makes it hard to make shells and skeletons for the seal life that need them.

2.No because it isn't harmful unless it builds up. But there is people who work to clean and limit the chances of build-up.


Hope this helps :)

The standard enthalpy of formation of BrCl(g) is 14.7 kJmol-1 . The standard enthalpies for the atomization of Br2(l) and Cl2(g)
natita [175]

Explanation:

Equation of the reaction:

Br2(l) + Cl2(g) --> 2BrCl(g)

The enthalpy change for this reaction will be equal to twice the standard enthalpy change of formation for bromine monochloride, BrCl.

The standard enthalpy change of formation for a compound,

ΔH°f, is the change in enthalpy when one mole of that compound is formed from its constituent elements in their standard state at a pressure of 1 atm.

This means that the standard enthalpy change of formation will correspond to the change in enthalpy associated with this reaction

1/2Br2(g) + 1/2Cl2(g) → BrCl(g)

Here, ΔH°rxn = ΔH°f

This means that the enthalpy change for this reaction will be twice the value of ΔH°f = 2 moles BrCl

Using Hess' law,

ΔH°f = total energy of reactant - total energy of product

= (1/2 * (+112) + 1/2 * (+121)) - 14.7

= 101.8 kJ/mol

ΔH°rxn = 101.8 kJ/mol.

What chemical process is responsible for the smell of vinegar in an old bottle of aspirin?
Oliga [24]

Chemical process is responsible for the smell of vinegar in an old bottle of aspirin is Hydrolysis of ester i.e. Aspirin.

Aspirin reacts with water leading to the formation of Acetic acid which is a Carboxylic acid derivative.

Aspirin on Hydrolysis forms Acetic acid and Salicylic acid.

The reaction shows up as a fizz when aspirin is added in water.

Aspirin is called Acetyl Salicylic acid and it helps to reduce:

  • Inflammation
  • Pain
  • Fever
  • Headache
  • Arthritis
  • Muscle pain
  • Tooth pain

Acetic acid or Ethanoic acid is a colorless liquid. It is an important carboxylic acid. It smells like vinegar.

Acetic acid is used for production of following:

  • Vinyl Acetate
  • Insecticides
  • Rubber
  • Acetic anhydride

Salicylic acid is a bitter compound which is colorless. It reduces acne and opens up the skin pores.
