Explain why it is important to assume that the rate of radioactive decay aka radioactivity will remain constant over time?

Answer and Explanation:

It's very important to assume that the rate of radioactive decay will remain constant over time to make scientists' lives easier when calculating the ages of fossils, compounds, etc.

If the rate changes, it would be extremely challenging for people to figure out the relative ages of rock strata, fossils, or other substances with radioactive elements in them. This is a fundamental assumption in order to be able to use radioactive dating.

Hope this helps!

A voltaic cell spontaneously converts1) electrical energy to chemical energy(2) chemical energy to electrical energy(3) electric
Varvara68 [4.7K]
A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2". Actually voltaic cell is an electrochemical cell that converts the chemical contained within it by the process of chemical reaction to produce electrical energy. The voltaic cell contains an anode and a cathode. Anode is an electrode where the oxidation occurs and cathode is the electrode where reduction occurs. The oxidation and the reduction part occurs in two separate parts of the cell known as half-cell.

A mixture initially contains AA, BB, and CC in the following concentrations: [A][A]A_1 = 0.550 MM , [B][B]B_1 = 1.40 MM , and [C
Alex787 [66]

Answer:

The value of the equilibrium constant KC is 1.244

Explanation:

A mixture initially contains A, B, and C in the following concentrations: [A] = 0.550 M, [B] = 1.40 M, and [C] = 0.600 M. The following reaction occurs and equilibrium is established: A+2B<->C

At equilibrium, [A] = 0.430 M and [C] = 0.720 M. Calculate the value of the equilibrium constant, Kc

Step 1: The balanced equation

A+2B<->C

Step 2: The initial concentrations

[A] = 0.550 M

[B]= 1.40 M

[C] = 0.600 M

Step 3: The concentraions at equilibrium

[A] = 0.550 -X = 0.430 M

[B]= 1.40 -2X M

[C] = 0.600 + X = 0.720 M

X = 0.120 M

[A] = 0.550 - 0.120 = 0.430 M

[B]= 1.40 -2*0.120 =  1.16 M

[C] = 0.600 + 0.120 = 0.720 M

Step 4: Calculate Kc

Kc = [C] / [A][B]²

Kc = 0.720 / (0.430*1.16²)

Kc = 1.244

The value of the equilibrium constant KC is 1.244
