Answer:

B) Because modern corals live in warm, shallow seas, we can infer the same

environment existed during the Devonian period, where the Kimberleys are

today

Explanation:

Based on the law of Uniformitarianism we can infer the environment that existed during the formation of the Devonian limestone and the Barrier Reef today.

Since the process that occurs in times past are still occurring today, the depositional environment must have been the same.
The limestone in Kimberly suggests that they must have formed under warm, shallow sea very similar to that of the Barrier reef today.
This interpretation is only made possible by the law of uniformitarianism.

How many grams of sodium chloride are contained in 250.0 g of a 15% NaCl solution?

kramer

Given concentration of NaCl=15%

Means ,

In every 100g of Solution 15g of NaCl is present .

Now

Given mass=250g

So ,

$\\ \Large\sf\longmapsto 250\times 15\%$

$\\ \Large\sf\longmapsto 250\times \dfrac{15}{100}$

$\\ \Large\sf\longmapsto 37.5g$

<u>37.5g of NaCl present in 250g of solution.</u>

The octet rule states that atoms will gain, lose, or share valence electrons to get a full outer shell (orbital). Explain in you

bezimeni [28]

Answer:

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

At equilibrium, ________. At equilibrium, ________. all chemical reactions have ceased the rate constants of the forward and rev

balandron [24]

Answer:

<em>At equilibrium, the rate of the forward, and the reverse reactions are equal.</em>

Explanation:

In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.

NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.
