Answer:
Explanation:
Hi there!
2Pb (no₃) -------> 2Pb + 4no₂ + o₂
Molecular mass of 4no₂ = 184g
Molecular mass of o₂ = 32g
From the reaction;
When 184 g of no₂ was formed 32 g of oxygen was formed.
When 1 g of no₂ was formed 32/184 g of oxygen was formed.
When 11.5 g of no₂ was formed (32/184)*11.5 g of oxygen was formed.
Therefore, when 11.5 g of no₂ was formed 2 g of oxygen was formed.

Binet's intelligence test measures the level of knowledge and understanding taking into account the age of the subject, increasing the difficulty and level of abstraction of the tests with age.
<h3>What is Binet's intelligence test?</h3>
It is a standardized test that measures intelligence and cognitive abilities in children and adults.
This test conceives intellectual development as the progressive acquisition of basic intellectual mechanisms, in such a way that these the levels of knowledge and understanding must correspond to their chronological age.
Therefore, we can conclude that Binet's intelligence test measures intelligence or common sense (based on the ability to understand, judge and reason correctly) corresponding to the chronological age.
