Law of superposition

Principle of cross-cutting

Explanation:

The geologic precepts that would be used to determine the relative ages of the rock strata are the law of superposition of strata and the principle of cross-cutting.

The law of superposition of strata states that "in an undisturbed sequence of rock strata, the oldest layer is usually at the bottom and the youngest on top".
From this law we understand that the oldest layer will be at the bottom if the rock has not been disturbed.
Here the rock has been disturbed by folding and we need to unravel to fold and see how the rock sequence originally was laid.

The principle of cross-cutting states that "faults are younger than the rocks they cut through". Structures in rocks are younger than rock layers they cut through.

A fault or joint will only pass through a rock that has been formed before it occurred. Subsequent rocks will be younger than the fault.

Metals are cunductor of heat and electricity prove this statement

Grace [21]

Answer:Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

Draw the best lewis structure for h 2 co 3 and calculate the formal charge on carbon.

schepotkina [342]

The Lewis structure of Carbonic Acid (H₂CO₃) is given below. In structure it is shown that carbon has a double bond with one oxygen atom and two single bonds with hydroxyl groups.

Formal Charge;
Formal charge is caculated as,

Formal charge = # of valence e⁻ - [# of lone pair of e⁻ + 1/2 # of bonded e⁻]

Formal charge on Carbon;

Formal charge = 4 - [ 0 + 8/2]

Formal charge = 4 - [4]

Formal charge = Zero

In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements w

Karo-lina-s [1.5K]

Answer:

Theoretical yield of C = 7.9 g

Actual amount of C isolated = 5.0 g

Explanation:

Given that in the reaction, Compound A combines with Compound B t o produce Compound C and no other products, the reaction is a combination reaction. The equation of the reaction is given below:

A + B ---> C

Part A:

From the measurement of the masses of A and B present before and after the reaction, the following values were obtained:

Initial mass of A = 4.0 g

Final mass of A = 0.0 g

Mass of A used up + 4.0 - 0.0 = 4.0 g

Initial mass of B = 9.0 g

Final mass of B = 5.1 g

Mass of B used up = 9.0 - 5.1 = 3.9 g

According to the law of conservation of mass, matter can neither be created nor destroyed but can change from one form to another. Therefore, theoretical yield of C equal the sum of the masses of A and B used up.

Theoretical yield of C = 4.0 + 3.9 = 7.9 g

Part B:

Given that the percent yield is 63.0 % = 0.63

Actual amount of C isolated = 0.63 * 7.9 = 5.0 g
