Which of the following is an acid-base neutralization reaction? (1 point)

GuDViN [60]

It would be NaOH + HCl → NaCl + H2O

NaOH is sodium hydroxide, which is a strong base. HCl is hydrochloric acid, which is a strong acid.

You have a strong base and a strong acid on the left side, however, at the result side, you end up with NaCl + H2O. Sodium chloride is simply table salt and H2O is just water, thus it has been neutralized.

3. A student carries out the clay-catalyzed dehydration of cyclohexanol starting with 10 moles of cyclohexanol and obtains 500 m

IrinaK [193]

Answer:

$49.45~%$

Explanation:

In this case, we have to start with the chemical reaction:

$C_6H_1_2O~->~C_6H_1_0~+~H_2O$

So, if we start with 10 mol of cyclohexanol ( $C_6H_1_2O$ ) we will obtain 10 mol of cyclohexanol ( $C_6H_1_0$ ). So, we can calculate the grams of cyclohexanol if we calculate the molar mass:

$(6*12)+(10*1)=82~g/mol$

With this value we can calculate the grams:

$10~mol~C_6H_1_0\frac{82~g~C_6H_1_0}{1~mol~C_6H_1_0}=820~g~C_6H_1_0$

Now, we have as a product 500 mL of $C_6H_1_0$ . If we use the density value (0.811 g/mL). We can calculate the grams of product:

$500~mL\frac{0.811~g}{1~mL}=405.5~g$

Finally, with these values we can calculate the yield:

$%~=~\frac{405.5}{820}x100~=~49.45%$ %= (405.5/820)*100 = 49.45 %

See figure 1

I hope it helps!

Explain how glucose and starch are related

weeeeeb [17]

Answer:

Starch is the stored form of sugars in plants and is made up of a mixture of amylose and amylopectin (both polymers of glucose). ... The cells can then absorb the glucose. Starch is made up of glucose monomers that are joined by α 1-4 or α 1-6 glycosidic bonds.

Lonic bonds form between oppositely charged

fomenos

answer:

ionic bonds form between oppositely charged ions

explanation:

an ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal.
a covalent bond involves a pair of electrons being shared between atoms.

Which element is closely associated with the field of organic chemistry?

slega [8]

Answer:

Carbon

Explanation:

The field of organic chemistry is the field of the study of the compounds of carbon mostly with hydrogen but they can contain the presence of other atoms such as oxygen, nitrogen, sulfur even metals such as lithium. It studies the structure, properties, synthesis and reactions of these compounds. The field of organic chemistry is the field of living organisms as they are mostly are formed by organic compounds hence its name organic.
