Answers

Answer 1
Answer:

Electrolytes are defined as those compounds which can dissociates generating ions in solution or melt, it gains the ability to conduct electricity.

What is electrolytes?

An electrolyte is just a chemical substance that conducts electricity either melted or mixed into a solution by forming ions. Sodium chloride is an example of an electrolyte. Any molten or dissolved chemical substance that ionizes and conducts electricity.

What is solution?

A solution is a homogenous mixture of two components, usually a solute and a solvent. A solution can be found in any of the three states of matter: liquid, solid, or gas. The solute and solvent are the two components that make up the solution.

A certain batch of fireflies were observed to "flash" at the rate of 13.0 times per minute at 25°C, and at the lower rate of 5.0 times a minute at a temperature of 15°C. Assume that the flashing is the result of an overall chemical reaction that has a single rate limiting step with the highest activation energy. Use this data to estimate the activation energy for this slowest step. You can assume that the concentrations of "reactants" in the fireflies do not depend on temperature.

Answers

Answer:

Ea=  1.8 x 10⁵ J

Explanation:

Use the Arrehenius equation to obtain the activation energy by comparing them at the two temperatures as follows:

k = A e^-Ea/RT     where k = rate constant

                                        A = Arrhenius constant

                                        Ea = activation energy

                                        T = temperature in degrees K

since we know the constants k₁ and k₂

k₁ = A e^ -Ea/RT₁  and K₂ = A e - Ea/RT₂

dividing them side by side:

k₁ = A e^ -Ea/RT₁  /  A e - Ea/RT₂

ln k₁/k₂ =  Ea/R (1/T₂ - 1/T₁ )

We have to be careful with what we call T₁ an T ₂ and be consistent then with k₁ and k₂. Lets use T₁ = 25 ºC =( 273 + 25 ) K = 298 K

so k₁ = 13.0 times/min

and likewise for k₂ = 5.0 times/min ( T = 273 + 15 ) K = 288 K

ln ( 13.0/ 5.0 ) = Ea/ 8.314 j//k ( 1/288K - 1/298K ) =

ln (2.60) x 8.314 = Ea ( 1.2 x 10 ⁻⁴)   Ea = 1.8 x 10⁵ J

Water (2510 g ) is heated until it just begins to boil. If the water absorbs 5.09×105 J of heat in the process, what was the initial temperature of the water?

Answers

Ans: Initial temperature of water = 51.5 C

Given:

Mass of water (m) = 2510 g

Heat absorbed by water (q) = 5.09*10⁵ J

Final temperature of water = boiling point = T2 = 100 C

To determine:

The initial temperature, T1

Explanation:

Heat absorbed by water is given as:

q = mc(T2-T1)

c = specific heat of water = 4.18 J/gC

5.09*10⁵ = 2510 g*4.18 J/gC *(100-T1)

T1 = 51.5 C

Answers

The combination of chemical reactions through which an organism builds up or breaks down materials as it carries out its life processes is called metabolism.


Its main purpose is to convert food to energy.



Explanation:


Metabolism can even confer with the add of all chemical reactions that occur in living organisms, together with digestion and therefore the transport of drugs into and between totally different cells, during which case the set of reactions among the cells is named intermediator metabolism or intermediate metabolism.

Half life worksheet answer key 1. How long does it take a 100.00g sample of As-81 to decay to 6.25g?

Answers

The half life of As-81 is 33 seconds;
6.25 g = 100 × (1/2)^n, where n is the number of half lives
(1/2)^n = 0.0625
        n = 4
Thus, the time taken = 33 ×4 = 132 seconds
Therefore, it takes 132 seconds or 2 mins 12 seconds for it to decay to 6.25 g

Answer:

132 seconds ( 2 Minutes 12 seconds).

Explanation:

Half life is basically the time it takes for a compound to decay to half of it's original mass.

In this problem, the compound is As. The half life of As-81 is 33 seconds. This means it takes 33 seconds for 100 g of As-81 to decay to 50g. The question however id to find the time it takes for it to decay to 6.25g.

We find how many half life's it would take,

100 --> 50 (First half life)

50 --> 25  (Second half life)

25 --> 12.5 (Third half life)

12.5 --> 6.25 (Fourth half life)

This means the total time is 4 * 33 (Half life) = 132 seconds ( 2 Minutes 12 seconds).
