Answer:

1,2-pentadiene < 1,4-pentadiene < cis-1,3-pentadiene < trans-1,3-pentadiene

Explanation:

1,3-pentadiene have two double bonds which are in conjugation, due to which delocalization occur. Delocalization of electrons more provide stability to 1,3-pentadiene as compared to 1,4-pentadiene and 1,2-pentadiene.

Among cis form and trans form of 1,3-pentadiene, trans form is more stable beacuse of less steric hindrance.

1,2-pentadiene is an example of cumulated diene. 1,4-pentadiene is an isolated diene. Cumulated dienes are less stable as two double bonds are present on the same carbon which leads to high electron density.

So, 1,2-pentadiene will be the least stable.

Order of dienes from least stable to most stable is as follows:

1,2-pentadiene < 1,4-pentadiene < cis-1,3-pentadiene < trans-1,3-pentadiene

If 18 mL of methanol is used to make an aqueous solution that is 15% methanol by volume, how many mL of solution is produced?

Yuri [45]

Answer:

120.0 mL.

Explanation:

As it is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles after dilution.

We suppose that the initial W% of methanol is 100.0 %

∴ (W%V) before dilution = (W%V) after dilution.

W% before dilution = 100.0 %, V before dilution = 18.0 mL.

W% after dilution = 15.0 %, V after dilution = ??? mL.

∴ V after dilution = (W%V) before dilution/W% after dilution = (100.0 %)(18.0 mL)/(15.0%) = 120.0 mL.

How many grams is 5.8 moles of hydrochloric acid (HCI)? Answer to the nearest 0.01 g.

Anvisha [2.4K]

Answer:

211.47 grams

Explanation:

We need to set up a dimensional analysis to solve this problem by converting from moles to grams.

First, find the molar mass of HCl. Since the molar mass of H (hydrogen) is 1.01 g/mol and the molar mass of Cl (chlorine) is 35.45 g/mol, then the molar mass of HCl is:

1.01 + 35.45 = 36.46 g/mol

We have 5.8 moles of HCl, so multiply by its molar mass:

(5.8 mol) * (36.46 g/mol) = 211.468 ≈ 211.47 g

The answer is thus 211.47 grams.

Where is energy stored in a carbon-based molecule like glucose? responses the space between atoms the space between atoms the hy

Alik [6]

Food is made up of organic (carbon-containing) molecules that contain chemical bonds between their atoms that act as energy storage units. In addition to using the energy in food to fuel life processes, organisms construct larger organic molecules, such as proteins, DNA, and fats (lipids), using the atoms from food molecules.

What is glucose ?

The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
