Answer:

The principle of faunal succession state "Specific groups of organisms have followed one another in a definite sequence through the Earth's history."

Explanation:

Faunal succession basically means is that the fossils of the flora and fauna of different eras can be found in a specific order and never in the same strata. This allows the geologists to determine the time sequence and also to identify the various strata by dating the fossils that are found in each of them. The older version of fossils are found beneath the fossils of modified versions. For example fossils of simple feathers that cannot support flight are found to be succeeded by fossils of more complex feathers.

How many moles of hydrogen molecules (h2) are present in 9 x 1023 molecules of hydrogen?

Marta_Voda [28]

Hello

So the molar mass of a Hydrogen molecule is 2. If you have 10 grams of Hydrogen molecules, you have 5 moles of Hydrogen molecules (10 moles of Hydrogen atoms). Avogadro's number is 6.0225x10^23. This means that one mole of a substance has that many particles.

Have a nice day

Which net ionic equation best represents the reaction that occurs when an aqueous solution of barium chloride is mixed with an a

vovangra [49]

Answer : The net ionic equation will be:

$Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)$

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

$BaCl_2(aq)+Li_2SO_4(aq)\rightarrow 2LiCl(aq)+BaSO_4(s)$
