When the protons and neutrons combine to form a nucleus, the mass that disappears
The answer is inductive reasoning.
Using specific observations to make generalizations means inductive reasoning.
Inductive reasoning is opposite to deductive reasoning, it makes generalization from specific observations. Generalization is done from specific set of observations. After generalization, conclusions are drawn from the data. Inductive reasoning has its place in scientific method.
Answer:
1.015g
Explanation:
From the question,
Mass of Al used = 0.660g
The percentage yield = 63.5%
Mass of Alum used = y
To find the mass of Alum used, do the following:
%yield = Mass of Al /Mass and Alum
65% = 0.660/y
65/100 = 0.660/y
Cross multiply
65 x y = 0.660x100
Divide both side by 65
y = (0.660x100) / 65
y = 1.015g
The mass of alum obtained is 1.015g
