Answer:
This question is asking whether the statement is TRUE OR FALSE
THE ANSWER IS TRUE
Explanation:
A concept, as rightly defined, is the general idea of an entity, which can include objects, events, animals, or people based on common features, traits, or characteristics. Hence, the CONCEPT of something refers to a a generalized idea about that particular thing.
A concept in other words is our thought about something i.e. how we conceive or think that thing to be. Concept is a phenomenon of the "MIND" since it is abstract and cannot be seen. Based on this, the definition given in the question is TRUE.
Answer:
Mass released = 8.6 g
Explanation:
Given data:
Initial number of moles nitrogen= 0.950 mol
Initial volume = 25.5 L
Final mass of nitrogen released = ?
Final volume = 17.3 L
Solution:
Formula:
V₁/n₁ = V₂/n₂
25.5 L / 0.950 mol = 17.3 L/n₂
n₂ = 17.3 L× 0.950 mol/25.5 L
n₂ = 16.435 L.mol /25.5 L
n₂ = 0.644 mol
Initial mass of nitrogen:
Mass = number of moles × molar mass
Mass = 0.950 mol × 28 g/mol
Mass = 26.6 g
Final mass of nitrogen:
Mass = number of moles × molar mass
Mass = 0.644 mol × 28 g/mol
Mass = 18.0 g
Mass released = initial mass - final mass
Mass released = 26.6 g - 18.0 g
Mass released = 8.6 g
