Identify whether the following example is qualitative or quantitative data.
The length of a rod

Quantitative data

Explanation:

Qualitative data:

Qualitative data is non statistical data. It only describes the properties or characteristics without numerical values.

For example:

The color of product any reaction is its qualitative property.

state of mater is also qualitative.

Quantitative data:

Quantitative data is statistical data. It describes the properties or characteristics with numerical values.

For example:

The length of rod is quantitative data because it is always given in numbers.

The height of someone is quantitative data.

Consider another example:

The 5 g of hydrogen and 5 gram of oxygen react to form 10 gram of water which is color less. In this example amount of reactants and products are quantitative data while the color of product is qualitative data.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
