Which equations shows the complete dissociation of a strong base?

Answers

Answer 1
Answer: The correct answer is the fourth option. The complete dissociation of a strong base is BOH + h20 -> B+ + OH- + H20 since this is the only base from the choices given. A base is a substance that accepts hydrogen ions.

Which
2 continents have the most obvious fit of the coastlines.
subject science

Answers

The East coastline of South America and the west coastline of Africa share the most obvious fit, it gave Wegener the first idea as evidence for the continental drift.

Two continents have the most obvious fit of the coastlines are the east coast of South America and the west coast of Africa.

Further explanation

According to the examination of a world map it reveals a striking match between the shapes of the east coast of South America and the west coast of Africa. Attached the map which shows the west coast of Africa in 1842 and also the map of the east coast of South America. According to the picture of the west coast of Africa in 1842,  we can see Sierra Leone and Freetown, where the West India Regiments arrived and departed from.

Two continents have the most obvious fit of the coastlines are the east coast of South America and the west coast of Africa, because the east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle.

Wegener discovered that their rock layers are fit just as it clearly.  All the landmasses used to be one great landmass called Pangaea. Due to plate tectonics, fire movements in the mantle of the earth, the continents are slowly through millions of years, spread farther apart.

What is conserved during a chemical reaction matter, energy, both, or niether?

Answers

Answer: Option (c) is the correct answer.

Explanation:

According to the law of conservation of energy or matter, it is stated that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Same applies to the matter that matter can be transformed from one form to another.  

Thus, we can conclude that during a chemical reaction both matter and energy is conserved.

Both energy and matter are conserved during a chemical reaction.

Further Explanation:

Chemical reaction

It is the process to convert one or more substances into different substances. Reactants are the substances that experience changes during chemical reactions whereas products are formed once the reaction is complete. The properties of products are usually different from those of reactants.

Law of conservation of mass:

According to this law, the mass of an isolated system can neither be created nor be destroyed in a chemical reaction. In other words, the mass of reactants will always be equal to the mass of products. The quantity of matter in any material is known as mass. The conservation of matter also holds good for chemical reactions.

Law of conservation of energy:

It states that the energy can neither be created nor be destroyed but can only be converted from one form to another.

Therefore both matter and energy are conserved during a chemical reaction.
