Answer:

The names of all continents is Pangaea given by Alfred Wegener in 1912

Explanation:

The name Pangaea or Pangea is derived from the Greek pan that in english means Whole and Gaia that in english means Land. The idea was not new because before Wegener, other scientist have proposed the idea of a huge landmass and then the separation by continents. but Wegener was the first to use the term continental drift.

The continental drift means that the continents are moving form each other since millions of years due to the mantle convection. This theory has been replaced by tectonic plate theory.

Which action would shift this reaction away from solid calcium fluoride and toward the dissolved ions?a) adding calcium ionsb) a
Mila [183]

Answer:

c) removing fluoride ions.

Explanation:

Hello!

In this case, for this solubility product problem, it is very convenient to write the undergoing ionization reaction:

CaF_2(s)\rightleftharpoons Ca^{2+}(aq)+2F^-(aq)

In such a way, via the Le Chatelier's principle, we remember that the addition of reactants shifts the reaction towards products, adding products shifts the reaction towards reactants, removing reactants shifts the reaction towards reactants and removing products shifts the reaction towards products. In means, that the best way to shift this reaction away from solid calcium fluoride and toward the dissolved ions is c) removing fluoride ions, because it is a product and its removal favors the formation of more products.

Best regards!

Calculate the volume of a box, in cubic centimeters, which is 423 cm long, 12 cm wide, and 25 cm high. Report your answer with c
liq [111]

Answer:

130,000 cubic centimeters

Explanation:

The volume of a box is its length multiplied by its width multiplied by its height (lwh). 423 times 12 times 25 is 126,900. When multiplying, the number of significant figures is the same as the number with the least number of significant figures. The correct number of significant figures in this example is 2, so 126,900 would need to round up to 130,000 in order to have 2 significant figures.
