The principle of conservation of mass asserts that mass cannot be created or eliminated. Given that element A has a mass of 2 g/mol and element B has a mass of 3 g/mol, the total mass of compound AB equals the combined molar masses: 2 g/mol + 3 g/mol results in 5 g/mol for AB. As for A2B3, the calculation is as follows: A2 has 2 multiplied by 2, yielding 4 g/mol, while B3 equals 3 multiplied by 3, which gives 9 g/mol. Consequently, A2B3 amounts to 13 g/mol.
Hello! Your inquiry seeks to identify the environmental factor resulting in diminished genetic diversity within a tuna population. The accurate response is B: An increase in pollution.
I think the state change illustrated in the diagram is deposition.
Deposition is the transformation of gases into solids without transitioning through a liquid phase. It is the reverse process of sublimation.
A key distinction between gases and solids lies in the spacing of molecules; gases have large spaces between molecules, whereas solids have very minimal spacing, resulting in solids being more densely packed. This is illustrated in the diagram showing the transition from gases to solids.
