a) ionic and covalent bonding​

Answers

Answer:

Ionic bonds - an intramolecular force exist in a nonmetal and metal compounds such as NaCl. The Na donate 1 electon to Cl to complete its octet rule.

Covalent bond - an intramolecular force exist in a nonmetal and nonmetal compounds such as bonds O2, Cl2, CO2, sugar, proteins and most of organic compounds and biomolecules by sharing electrons to bond.

There are two types of covalent bonds: polar and nonpolar. Polar bond is a bond between two different nonmetal atoms of different electronegativities. While nonpolar bond is a bond between the same atom or two differenct atoms of the same electronegativities (if there is). Their electronegativities pull will cancel so that their overall polarity is zero.

Answer:

10.99s

Explanation:

Given parameters:

Speed of the fly = 9.1m/s

Distance flown = 100m

Unknown:

Time taken to fly this distance = ?

Solution:

Speed is distance divided by the time;

  Mathematically;

            Speed  = [tex]\frac{distance}{time}[/tex]  

             Time  = [tex]\frac{distance}{speed }[/tex]  

Insert the parameters and solve;

        Time  = [tex]\frac{100}{9.1}[/tex]   = 10.99s

how can you test a sample of soil for acidity or alkalinity​

Answers

Answer:

Scoop a soil sample into a fresh container, add 1/2 cup of water, and mix. Then, add 1/2 cup of baking soda. If the soil bubbles or fizzes, the soil is acidic. The reaction you're seeing is the result of acidic soil coming into contact with an alkaline substance (baking soda).

Explanation:

[tex]% yield = 100.\frac{actual yield}{theoretical yield}[/tex]% [tex]yield[/tex] = [tex]100. \frac{actual \ yield}{theoretical \ yield}[/tex]

Actual yield = % yield.(theoretical yield) / 100

Answers

Answer:

Explanation:

Polar solute dissolve in polar solvent and non polar solute dissolve in non polar solvent. Therefore the order of solubility is calcium bromide> calcium chloride>calcium bicarbonate>calcium carbonate.

What is solubility?

Solubility shows the extent of solubility of a solute in solvent to make a solution. Solute is substances that is present in small amount. solvent is a substance that is present in large amount. Its SI unit is gram per liter or g/L.

Bond strength affect the solubility of a solute in solvent. weaker the bond strength is, more the solubility is. The weaker bond can be easily broken by water molecule

Calcium bromide is more soluble than calcium chloride as the bond strength in calcium bromide is weaker than calcium chloride. Calcium bicarbonate is more soluble than calcium carbonate.

Therefore the order of solubility is calcium bromide> calcium chloride>calcium bicarbonate>calcium carbonate.

Answers

Answer:

B

Explanation:

I did it

Neither physical not chemical changes alter the atomic structure of a substance. The correct option is b.

What are chemical changes?

When one chemical substance is transformed into one or more different substances, such as when iron becomes rust, a chemical change occurs.

Chemical changes occur as a result of chemical reactions, and the resulting substances have different properties due to the different arrangements of their atoms and molecules.

Physical changes affect a chemical substance's form but not its chemical composition.

Physical changes can be used to separate mixtures into their component compounds, but not to separate compounds into chemical elements or simpler compounds.

Physical or chemical changes have no effect on a substance's atomic structure.

Thus, the correct option is b.

Benzoic acid, C6H5COOH, is another derivative of benzene. The pH of an aqueous solution of benzoic acid at 298 K is 2.95. Determine the concentration of hydroxide ions in the solution,

Answers

Answer:

[OH⁻] = 8.91x10⁻¹²M

Explanation:

In aqueous solutions, the [OH] and [H⁺] are associated in the equation of hydrolisis of water:

1x10⁻¹⁴ = [OH⁻] [H⁺]

With pH, we can solve for [H⁺] and obtain, the [OH⁻] using this equation:

pH = -log [H⁺]

[H⁺]= 10^-pH

[H⁺] = 1.122x10⁻³M

1x10⁻¹⁴ = [OH⁻] [1.122x10⁻³M]

[OH⁻] = 8.91x10⁻¹²M
