Which of the following are properties of compounds formed by covalent bonding? Select all that apply:

When you dissolve an covalent compound in water, the solution does not conduct electricity

Covalent compounds often have lower melting points than ionic compounds.

When you dissolve an covalent compound in water, the solution conducts electricity.

Covalent compounds form when combining two or more non-metal atoms.

Covalent compounds form when combining a two metal atoms.

Covalent compounds form when combining a metal atom with a non-metal atom.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
