Answer:

D. 5.6 g/cm^3

Explanation:

On the average seismic velocity increases with increase in depth due higher the pressure and more compaction

sand and shales in the Niger Delta Basin density–velocity relationship is

P = 0.31×V^0.25

A derivation of the original Gardner equation to calculate the average densities for sands and shales in wells.

ρ = α ×V^β

where

ρ = bulk density in g/cm3,

V = P-wave velocity,

α = 0.31 for V (m/s) and 0.23 for V(ft/s) and

β = 0.25.

Such that

ρ = 0.31 ×V^0.25

So the fastest seismic velocity will be in the densest material which is D. 5.6 g/cm3

Explain the scientific meaning and use of the word "transformation".
sladkih [1.3K]

Transformation in chemistry is scientifically used to explain the process of changing one compound to another in a chemical reaction.

<h3>What is transformation?</h3>

The word "transformation" has a very special significance in chemistry. We know that in English, to transform would simply imply to change from one form to another. This is not quite far from its meaning in the parlance of chemistry.

The word transformation is normally applied in the area of chemical reactions especially as it has to do with reaction with in organic chemistry. It has to do with the change from one molecule to another and this is of great importance in the discussion of synthetic chemistry.

As such, the word transformation in chemistry is scientifically used to explain the process of changing one compound to another in a chemical reaction.

A tank of oxygen has a volume of 1650 L. The temperature of the gas inside is 35?C. If there are 9750 moles of oxygen in the tan
Paul [167]

Answer:

2192.64 PSI.

Explanation:

  • From the general law of ideal gases:

<em>PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the container in L (V = 1650 L).

n is the no. of moles of the gas in mol (n = 9750 mol).

R is the general gas constant (R = 0.082 L.atm/mol.K).

T is the temperature of the gas in (T = 35°C + 273 = 308 K).

∴ P = nRT/V = (9750 mol)(0.082 L.atm/mol.K)(308 K)/(1650 L) = 149.2 atm.

  • <u><em>To convert from atm to PSI:</em></u>

1 atm = 14.696 PSI.

<em>∴ P = 149.2 atm x (14.696 PSI/1.0 atm) = 2192.64 PSI.</em>

When the following aqueous solutions are mixed together, a precipitate forms. Balance the net ionic equation in standard form fo
rewona [7]

<u>Answer:</u>

<u>For (a):</u> The balanced net ionic equation is 2Ag^{+}(aq)+S^{2-}(aq)\rightarrow Ag_2S(s) and the sum of coefficients is 4

<u>For (b):</u> The balanced net ionic equation is Pb^{2+}(aq)+2Cl^{-}(aq)\rightarrow PbCl_2(s) and the sum of coefficients is 4

<u>For (c):</u> The balanced net ionic equation is Ca^{2+}(aq)+CO_3^{2-}(aq)\rightarrow CaCO_3(s) and the sum of coefficients is

<u>For (d):</u> The balanced net ionic equation is Ba^{2+}(aq)+2OH^{-}(aq)\rightarrow Ba(OH)_2(s) and the sum of coefficients is 4

<u>For (e):</u> The balanced net ionic equation is Ag^{+}(aq)+Cl^{-}(aq)\rightarrow AgCl(s) and the sum of coefficients is 3

<u>Explanation:</u>

Net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.

  • For (a): Sodium sulfide and silver nitrate

The balanced molecular equation is:

Na_2S(aq)+2AgNO_3(aq)\rightarrow 2NaNO_3(aq)+Ag_2S(s)

The complete ionic equation follows:

2Na^{+}(aq)+S^{2-}(aq)+2Ag^+(aq)+2NO_3^{-}(aq)\rightarrow 2Na^+(aq)+2NO_3^-(aq)+Ag_2S(s)

As sodium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

2Ag^{+}(aq)+S^{2-}(aq)\rightarrow Ag_2S(s)

Sum of the coefficients = [2 + 1 + 1] = 4

  • For (b): Lead(II) nitrate and sodium chloride

The balanced molecular equation is:

2NaCl(aq)+Pb(NO_3)_2(aq)\rightarrow 2NaNO_3(aq)+PbCl_2(s)

The complete ionic equation follows:

2Na^{+}(aq)+2Cl^{-}(aq)+Pb^{2+}(aq)+2NO_3^{-}(aq)\rightarrow 2Na^+(aq)+2NO_3^-(aq)+PbCl_2(s)

As sodium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

Pb^{2+}(aq)+2Cl^{-}(aq)\rightarrow PbCl_2(s)

Sum of the coefficients = [2 + 1 + 1] = 4

  • For (c): Calcium nitrate and potassium carbonate

The balanced molecular equation is:

K_2CO_3(aq)+Ca(NO_3)_2(aq)\rightarrow 2KNO_3(aq)+CaCO_3(s)

The complete ionic equation follows:

2K^{+}(aq)+CO_3^{2-}(aq)+Ca^{2+}(aq)+2NO_3^{-}(aq)\rightarrow 2K^+(aq)+2NO_3^-(aq)+CaCO_3(s)

As potassium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

Ca^{2+}(aq)+CO_3^{2-}(aq)\rightarrow CaCO_3(s)

Sum of the coefficients = [1 + 1 + 1] = 3

  • For (d): Barium nitrate and sodium hydroxide

The balanced molecular equation is:

2NaOH(aq)+Ba(NO_3)_2(aq)\rightarrow 2NaNO_3(aq)+Ba(OH)_2(s)

The complete ionic equation follows:

2Na^{+}(aq)+2OH^{-}(aq)+Ba^{2+}(aq)+2NO_3^{-}(aq)\rightarrow 2Na^+(aq)+2NO_3^-(aq)+Ba(OH)_2(s)

As sodium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions

The net ionic equation follows:

Ba^{2+}(aq)+2OH^{-}(aq)\rightarrow Ba(OH)_2(s)

Sum of the coefficients = [2 + 1 + 1] = 4

  • For (e): Silver nitrate and sodium chloride

The balanced molecular equation is:

NaCl(aq)+AgNO_3(aq)\rightarrow NaNO_3(aq)+AgCl(s)

The complete ionic equation follows:

Na^{+}(aq)+Cl^{-}(aq)+Ag^{+}(aq)+NO_3^{-}(aq)\rightarrow Na^+(aq)+NO_3^-(aq)+AgCl(s)

As sodium and nitrate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

Ag^{+}(aq)+Cl^{-}(aq)\rightarrow AgCl(s)

Sum of the coefficients = [1 + 1 + 1] = 3
