Why is Carbon so important to living things?

Back

Carbon is essential because it forms molecules easily, can create various shapes, and is a fundamental component of all living organisms.

Front

What property of water helps to moderate earth's temperature?

Back

Specific heat capacity allows water to absorb and release heat without significant temperature changes, helping to stabilize the climate.

Front

Which of the following is an organic compound? H2O, C6H12O6, NH2, OH

Back

C6H12O6 (glucose) is an organic compound because it contains carbon.

Front

What makes a molecule polar?

Back

A molecule is polar due to the unequal sharing of valence electrons, resulting in a distribution of charge.

Front

CO2 has _____ bonds between the Carbon and 2 Oxygens.

Back

CO2 has covalent bonds between the Carbon and the two Oxygen atoms.

Front

Define an organic compound.

Back

An organic compound is a chemical compound that contains carbon and is typically found in living organisms.

Front

What is the significance of water's cohesion property?

Back

Cohesion allows water molecules to stick together, which is crucial for processes like water transport in plants.

Front

Explain the term 'specific heat capacity'.

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.
