Alkanes are non-polar: not soluble in water

alcohol is polar: soluble in water

The polarity of alcohols is affected by the -OH (hydroxyl) group, more OH, more polar, while non-polarity of alcohols is influenced by the carbon chain. the longer the carbon chain, the lower the polarity, the lower the solubility

butane : alkane: not soluble

1-2, ethanediol: alcohol: has 2 OH

Butanol has a longer carbon chain than ethanol

So the order of solubility in water (from largest to smallest)

1-2, ethanediol, ethanol, butanol, butane

bogdanovich [222]

The correct option is B.

Carbon is an element with an atomic number of 6. Each atom of carbon is made up of electron, proton and neutron. Carbon has six protons and six neutrons in its atom but its number of neutrons differ. This is because carbon exhibit isotopy. The isotopes of carbon are: carbon 12, carbon 13 and carbon 14. Carbon 12 has 6 neutrons, carbon 13 has 7 neutrons and carbon 14 has 8 neutrons.

2 2. The energy stored in a substance that can be released when the substance reacts. A. Mechanical Energy B. Thermal Energy C.

vichka [17]

Answer:

C. Chemical Energy

Explanation:

The energy that stored in the substance or in compounds is called chemical energy which released when the substance reacts.

A substance is made up of atoms and molecules and chemical energy is present in those atoms or molecules. When a chemical reaction takes place, these energy released from atoms and molecules.

Chemical energy can be released in the form of thermal energy (heat) and mechanical energy (working ability).

Hence, the correct answer is "C. Chemical Energy".
