A net ionic equation is an equation where only the ions reacting to form a product is shown in the equation.

The net ionic equation of the reaction of the Fe3+ ion and sodium fluoride is shown below:

Fe3+ + 3F- ---> FeF3

When sodium fluoride is added to a solution of iron (iii) thiocyanate (red), the red colour disappears because the flouride ions displace the thiocyanate ions.

The population of a town after t years is represented by the function (t)=7248(0. 983)t. What does the value 0. 983 represent in the situation?

Answers

Answer:

Exponential function: A function is in the form of;  where a is the initial value and b is a factor which decides the exponential function increases or decreases.

If

0<b <1 , then the exponential function decreases.

b> 1,  then the exponential function increases.

Given the function:

Since this function f(t) represents the population of a town after t years.

Also, it is an exponential function.

here, b = 0.983 < 1

So, the function f(t) would be decreased by a factor of 0.983.

Therefore, the value 0.983 represents, the population of the town is 0.983 times the population of the town in the previous year.

Identify the relative molar amounts of the species in 0. 10 m kno3(aq). If the species are present in equal amounts, place them in the same box

Answers

The relative molar amounts of the given species are;

KnO₃ = 0 M

K⁺ = NO₃⁻ = 0.1 M.

H₃O⁺ = OH⁻ = 1 × 10⁻⁷  M

H₂O = 55.56 M

What is the Relative Molar Amount?

KnO₃ → K⁺ + NO₃⁻

In this dissociation, we see that 1 mole of KnO₃ produces 1 mol of K⁺ and 1 mol of NO₃⁻.

Thus, concentration of KnO₃ is 0 M while the concentration of  K⁺ and NO₃⁻ are both 0.1 M.

Now, concentrations of H₃O⁺ and OH⁻ depends solely on the autoionization of water.

Thus, concentration of H₃O⁺ is equal to concentration of OH⁻ = 1 × 10⁻⁷ M. Finally, concentration of H₂O is calculated from it's (1 g/mL) and molar mass of H₂O is 18 g/mol. Thus, concentration = (1/18) * 1000= 55.56 M
