When making a guess, you are forming a hypothesis.

A hypothesis is a statement you make based on your observations of a certain phenomenon, so it's an educated guess.

You will then carry out an experiment whose results will hopefully support your hypothesis.


Explanation:

Hypothesis is a supposition or projected clarification created on the premise of restricted proof as a place to begin for more investigation.A hypothesis may be a tentative, testable answer to a scientific question. Once a person encompasses a scientific question she is fascinated by, the person reads up to search out out what's already far-famed on the subject. Then she uses that data to make a tentative answer to her scientific question. Typically folks discuss with the tentative answer as "an educated guess."

Consider a situation in which 211 g
Stella [2.4K]

Answer:

3.00 mol

Explanation:

Given data:

Mass of P₄ = 211 g

Mass of oxygen = 240 g

Moles of P₂O₅ = ?

Solution:

Chemical equation:

P₄ + 5O₂       →     2P₂O₅

Number of moles of P₄:

Number of moles = mass/ molar mass

Number of moles = 211 g / 123.88 g/mol

Number of moles = 1.7 mol

Number of moles of O₂ :

Number of moles = mass/ molar mass

Number of moles = 240 g / 32g/mol

Number of moles = 7.5 mol

Now we will compare the moles of product with reactant.

                       O₂         :         P₂O₅

                        5          :           2

                        7.5       :        2/5×7.5 = 3.00

                       P₄          :         P₂O₅

                        1           :           2

                       1.7         :       2×1.7 = 3.4 mol

Oxygen is limiting reactant so the number of moles of P₂O₅ are 3.00 mol.

Mass of P₂O₅:

Mass = number of moles × molar mass

Mass = 3 mol ×283.9 g/mol

Mass = 852 g
