When baking soda is mixed with vinegar, which type of reaction has taken place?

1 answer:

8 0

Answer:
<span>When baking soda is mixed with vinegar, a Neutralization reaction takes place.

Explanation:
The reaction of Baking sode (NaHCO</span>₃) and Vinegar (Acetic Acid) takes place in two steps.

Step 1:
In first step a Double Displacement Reaction takes place between baking soda and acetic acid.

NaHCO₃ + CH₃COOH → CH₃COONa + H₂CO₃

Step 2:
The Carbonic acid (H₂CO₃) formed in first step undergoes Decomposition Reaction as it is unstable.

H₂CO₃ → CO₂ + H₂O

What is soil? where do the water and nutrients found in the soil come from?

Liono4ka [1.6K]

Answer:

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

We get these from the plants that grow, and the animals that we eat that eat the plants. Most soils have a large supply of nutrients in them, and they get taken up by plants when plants absorb water. Soils need to be healthy to grow large quantities of plants, and animals need plants to grow strong.

Compute the percent ionic character of the interatomic bonds for the following compounds : a. TiO2 b. ZnTe c. CsCld. InSb e. MgC

sesenic [268]

Answer:

a. 63.2%

b. 11.7%

c. 73.3%

d. 0.995%

e. 55.5%

Explanation:

An ionic compound is a compound that is formed by ions, so one of the elements must donate electrons (which is the cation, the positive ion), and the other will receive these electrons (which is the anion, the negative ion).

The power of an element has to attract the electrons is called electronegativity, and so, as higher is the difference of electronegative of the elements, it is more probable that one of them will "still" the electrons and will form an ionic compound. The percent of this ionic character can be found by the Pauling's equation:

$%IC = (1 - e^{-0.25*(x_A - x_B)^2})$ *100%

Where $x_A - x_B$ is the electronegativity difference of the elements. Thus, consulting an electronegativity table:

a. $x_{Ti}$ = 1.5

$x_{O}$ = 3.5

$%IC = (1 - e^{-0.25*(3.5 - 1.5)^2})$ *100%

%IC = 63.2%

b. $x_{Zn}$ = 1.6

$x_{Te}$ = 2.1

$%IC = (1 - e^{-0.25*(2.1 - 1.6)^2})$ *100%

%IC = 11.7%

c. $x_{Cs}$ = 0.7

$x_{Cl}$ = 3.0

$%IC = (1 - e^{-0.25*(3.0 - 0.7)^2})$ *100%

%IC = 73.3%

d. $x_{In}$ = 1.7

$x_{Sb}$ = 1.9

$%IC = (1 - e^{-0.25*(1.9 - 1.7)^2})$ *100%

%IC = 0.995 %

e. $x_{Mg}$ = 1.2

$x_{Cl}$ = 3.0

$%IC = (1 - e^{-0.25*(3.0 - 1.2)^2})$ *100%

%IC = 55.5%

What is a limitation of using a chemical formula, such as C6H12O6, to represent a compound?

Kaylis [27]

The chemical formula does not show how the atoms are connected to one another.
When we write the chemical formula of any substance, we are not able to understand the spatial arrangement of that substance's atoms. This is extremely important in organic compounds, which exhibit different physical characteristics as well as different chemical characteristics due to the way their atoms are arranged in space. These isomers are known as enantiomers.
