Answer:

The reference ranges for blood potassium levels are as follows : Adult/elderly: 3.5-5.0 mEq/L or 3.5-5.0 mmol/L (SI units) Child: 3.4-4.7 mEq/L. Infant: 4.1-5.3 mEq/L.

A student performs a reaction that makes aluminum oxide. According to her calculations, she should expect to make 115.2 grams. S

tiny-mole [99]

Answer:

The percentage of the student is 58.17%.

Explanation:

Expected yield of aluminum oxide = 115.2 g

Actual yield of aluminum oxide produced =66.9 g

The percentage yield is calculated by dividing actual yield by expected yield and then multiplying it with hundred.

Percentage yield:

$\frac{\text{Actual yield}}{\text{Expected yield}}\times 100$

$\% Yield=\frac{66.9 g}{115.2 g}\times 100=58.17\%$

The percentage of the student is 58.17%.

A voltaic cell is based on the reduction of ag (aq) to ag(s) and the oxidation of sn(s) to sn2 (aq).

Annette [7]

Half-reaction for the cell's anode is given below:

Anode : $\\Sn(s) \rightarrow Sn^{2+} (aq) +2e^{-}$

The anode is defined as the electrode at which electrons leave the cell and oxidation occurs, and the cathode as the electrode at which electrons enter the cell and reduction occurs. The anode is usually the positive side.

SashulF [63]

Balanced chemical reaction: 2CH₄(g) ⇄ C₂H₂(g) + 3H₂(g).

1) In a chemical reaction, chemical equilibrium is the state in which both reactants (methane CH₄) and products (ethyne C₂H₂ and hydrogen H₂) are present in concentrations which have no further tendency to change with time.

2) At equilibrium, both the forward and reverse reactions are still occurring.

3) Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products.
