you add 6.6g of iron to 29.00ml of water and notice that the voume of iron and water together is 29.84ml what is the density of
madreJ [45]

Explanation:

1L=1000mL

1dm³=1L

1dm³=1000cm³

29.84ml-29.00ml=0.84ml

Density=mass(g)/volume(cm³)

=6.6g/(0.84cm³)

8. The rate constant for the reaction below is 6.2 x 10−5 mol L−1s−1. If the initial concentration of A is 0.0500 M, what is its
Aloiza [94]

Answer:

The concentration after 115 seconds is 0.0496 M

Explanation:

Applying integrated rate law for a first-order reaction, we will have;

[A]_t = [A]_0e^{-kt}

where;

[A]_t is the concentration at a time t

[A]_0 is the initial concentration

k is the rate constant for the reaction

t is the given time

Given;

[A]_0  = 0.05 M

k = 6.2 x 10⁻⁵ mol L⁻¹s⁻¹

t = 115 seconds

Substitute these values and solve for [A]_t

[A]_t = [A]_0e^{-kt} = (0.05)*e^{-(6.2X10^{-5}*115)}\\\\

[A]_t = (0.05)(0.9929) =0.0496 M

Therefore, the concentration after 115 seconds is 0.0496 M

The electron configuration of an element is 1s ^ 2 * 2s ^ 2 * 2p ^ 6 describe what most likely happens when an atom of this elem
MatroZZZ [7]

The atom with the electron configuration has completely filled shells and will ordinarily not react with another atom.

<h3>Electronic configurations</h3>

Atoms with completely filled shells are said to be stable and will ordinarily not react with another atom irrespective of the number of valence electrons.

The S and P orbitals in the electron configuration have been completely filled. Only atoms with partially filled shells readily react with other atoms with partially filled shells.
