Over an interval of 3.00 s the average rate of change of the concentration of C was measured to be 0.0840 M/s. What is the final

concentration of D at the end of this same interval if its concentration was initially 3.000 M?

Answer:

Final Concentration = 3.252M

Explanation:

Let's bring out the data mentioned in the question.

Time, t = 3s

Rate = 0.0840 M/s

Initial Concentration = 3M

Final Concentration = x

The formular relating these parameters is;

Rate = ΔConcentration / ΔTime

Upon solving for ΔConcentration, we have;

ΔConcentration = Rate * ΔTime

ΔConcentration = 0.0840 * 3

ΔConcentration = 0.252

But ΔConcentration = Final Concentration - Initial Concentration

Hence,

Final Concentration = ΔConcentration + Initial Concentration

Final Concentration = 0.252 + 3

Final Concentration = 3.252M

State one type of additional information that could be used to determine if these three species are closely related.
Luda [366]

Answer:

Study the bone structure of limbs.

Explanation:

Study the bone structure of limbs can be used to find out the relatedness and relationship among three species because the pattern of bones structure is similar but the structure is different from one another due to different environmental conditions. This study provides important and useful information whether the three species are closely related or not. If they have similar bone structure than we can say that there are more chances that they are closely related to each other.

A 62.6-gram piece of heated limestone is placed into 75.0 grams of water at 23.1°C. The limestone and the water come to a final
VMariaS [17]
M₁ = mass of water = 75 g
T₁ = initial temperature of water = 23.1 °C
c₁ = specific heat of water = 4.186 J/g°C

m₂ = mass of limestone = 62.6 g
T₂ = initial temperature of limestone = ?
c₂ = specific heat of limestone = 0.921 J/g°C

T = equilibrium temperature = 51.9 °C
using conservation of heat
Heat lost by limestone = heat gained by water
m₂c₂(T₂ - T) = m₁c₁(T - T₁)
inserting the values
(62.6) (0.921) (T₂ - 51.9) = (75) (4.186) (51.9 - 23.1)
T₂ = 208.73 °C
in three significant figures
T₂ = 209 °C
