For the galvanic (voltaic) cell fe(s) + mn²⁺(aq) ⟶ fe²⁺(aq) + mn(s) (e° = 0.77 v at 25°c), what is [fe²⁺] if [mn²⁺] = 0.050 m an

Nuetrik [128]

The concentration of Iron in the galvanic (voltaic) cell Fe(s) + Mn²⁺(aq) ⟶ Fe²⁺(aq) + Mn(s) is 0.02297 M.

<h3>What is the Nernst Equation?</h3>

The Nernst equation enables us to identify the cell potential(voltage) in presence of non-standard conditions in a galvanic cell. It can be expressed by using the formula:

$\mathbf{E_{cell} = E_o - \dfrac{0.059}{n} \times log \dfrac{[Fe^+]}{[Mn^{2+}]}}$

where;

n = Number of electrons = 2
$\mathbf{E_o}$ = Initial voltage = 0.77 V
$\mathbf{E_{cell}}$ = Cell voltage = 0.78 V
$\mathbf{[Mn^{2+}]}$ = Manganese concentration = 0.050 M

Replacing the values into the above equation, we have:

$\mathbf{0.78 = 0.77 - \dfrac{0.059}{2} \times log \dfrac{[Fe^{2+}]}{[0.050]}}$

$\mathbf{0.78 -0.77= -0.0296\times log \dfrac{[Fe^{2+}]}{[0.050]}}$

$\mathbf{log^{-1} (-0.3378) = \dfrac{[Fe^{2+}]}{[0.050]}}$

$\mathbf{Fe^{2+} = (0.4594\times 0.050 )\ M}$

$\mathbf{Fe^{2+} =0.02297 \ M }$

The nurse assesses a postpartum woman's perineum and notices that her lochial discharge is moderate in amount and red. The nurse

Zarrin [17]

The type of lochia that the nurse would record the moderate discharge from the lochial is Lochia Rubra.

<h3>What is a lochia Rubra?</h3>

This is one of the stages in the condition known as lochia. It is considered the first stage and doesn't come with too heavy a flow.

Instead, the flow will be moderate and red and will eventually become light after about 4 days.

If someone ran over a dog could they die if they neck breaks

bixtya [17]

Explanation:

it depends on which part he ran over. dogs are said to be of high strength, any action of inadequate pressure or power would not necessarily be fatal. if the right amount of energy is used at the right spot, for example an artery running through the neck ( like the carotid artery) or something. but since the dog apparently vanished, we could make out that it is not exactly dead

Considering the different metrics available, a recovery time objective (RTO) is the period following a disaster that an individual IT system may remain offline.

<h3>What is recovery time objective?</h3>

The recovery time objective (RTO) is the maximum tolerable length of time that a computer, system, network or application can be down after a failure or disaster occurs.

Thus, considering the different metrics available, a recovery time objective (RTO) is the period following a disaster that an individual IT system may remain offline.
