Answer:

Sodium ions - Na⁺ - cation

Potassium ions - K⁺ cation

Chloride ions - Cl⁻ anion

Magnesium ions - Mg²⁺ cation

Calcium ions - Ca²⁺ cation

Phosphate ions - P³⁻ anion

Iron ions - Fe²⁺ cation

Zinc ions - Zn⁺ cation

Explanation:

Following is a list of 8 common but essential ions in the cells and fluids of human bodies:

1. Sodium ions helps in regulation and control the level of body fluids

2. Potassium ions help regulate cellular functions

3. Calcium ions are essential for building and maintaining strength bones and teeth. and have role in blood clotting, muscle contraction, and the transmission of nerve signals to cells.

4. Chloride ions are the main anions found outside body cells. They acts as counterions

5. Magnesium ions present in the bones

6. Phosphate ions present in body fluids act as the counterions.

7. Iron

8. Zinc

Acetaldehyde (CH3CHO) undergoes a Wolf-Kishner reaction, which is the addition of hydrazine (H2NNH2) with subsequent addition of

Anarel [89]

Answer:

Reduced, alkane

Explanation:

Wolf-Kishner reaction is a type of reduction reaction in which aldehydes and ketones are reduced to their corresponding alkane in the presence of a base.

This reaction occurs at high temperature.

Alkane formed has a same number of carbon as aldehyde and ketone.

If acetaldehyde undergoes a Wolf-Kishner reaction in the presence of base and heat, then ethane is formed. Nitrogen is formed as a byproduct.

Here, acetaldehyde is reduced to form ethane.

So, acetaldehyde undergoes a Wolf-Kishner reaction, which is the addition of hydrazine with subsequent addition of a base and heat. In this reaction, the aldehyde is reduced, resulting in alkane product.

It is known that 32g of oxygen takes up 24 litres of space at 25oC. Calculate the volume of oxygen that is needed to react compl

Gwar [14]

6 L of oxygen (O₂)

Explanation:

We have the following chemical reaction:

2 Mg + O₂ → 2 MgO

Now we calculate the number of moles of magnesium:

number of moles = mass / molar weight

number of moles of Mg = 12 / 24 = 0.5 moles

Taking in account the chemical reaction we devise the following reasoning:

if 2 moles of Mg react with 1 mole of O₂

then 0.5 moles of Mg react with X moles of O₂

X = (0.5 × 1) / 2 = 0.25 mole of O₂

mass = number of moles × molar weight

mass of O₂ = 0.25 × 32 = 8 g

Knowing the information given by the problem that 32 g of O₂ takes up 24 liters of space, we devise the following reasoning:

if 32 g of O₂ takes up 24 liters of space

then 8 g of O₂ takes up Y liters of space

Y = (8 × 24) / 32 = 6 L of O₂

Describe one possible economic impact of redox reactions. How might that impact be diminished?

Alex777 [14]

Redox reaction has a great economic impact. many product that we use in our daily lives are made using redox reaction. some of which are electroplating, that we use in our watches. and redox reaction also caused the rusting of irons, so buildings will rust and become brittle
