No material is truly homogeneous at the atomic level because atomic structures and arrangements can vary due to imperfections, defects, and variations in composition. Even within a seemingly uniform material, the distribution of atoms can exhibit fluctuations, such as in grain boundaries or the presence of impurities. Additionally, quantum mechanical effects can lead to variations in atomic behavior and interactions, further contributing to inhomogeneity. Thus, at the atomic scale, materials exhibit a complex and dynamic nature that prevents true homogeneity.
Visible particles would be heterogeneous elements of a mixture. A truly homogeneous mixture would have no visible particles. However, you could still have an approximately homogeneous mixture with visible particles, evenly distributed throughout the mixture.
No, a cement sidewalk is not a homogeneous mixture because it is made up of different components like cement, sand, gravel, and water that are not uniformly distributed throughout the material. It is more accurately described as a heterogeneous mixture.
A river is heterogeneous, because it has several different substances, such as broadly silt and fish (if you're thinking about it like that) or it is also contained, H20, O2, substances like that so either way it is heterogeneous.
It depends on how picky you want to be. Yes, having the same number of nucleons they have practically the same atomic mass. No, because they don't have exactly the same atomic mass due to differences in the nuclear binding energy (and hence aren't truly "isobars", even though that's what they're called). (NB: this usage of "isobar" is from nuclear chemistry and means "nuclei with the same number of nucleons." It's not the meteorological isobar, which is something quite different and wouldn't make any sense in the context of the question.)
No the word truly is an adverb. You can easily spot most adverbs as they end in -ly.

The answer to whether your father's house is truly a house of prayer depends on the level of reverence and devotion to prayer that is practiced there.
No, I am not. Included in me is also the inability to perceive things that do not have material existence (and so do not truly exist), such as other peoples' thoughts.
That is a question of opinion. And my opinion is yes as I truly believe it saved around a million lives.
The genetic material that viruses have is RNA. Viruses are unable to truly carry out the processes associated with holding their own DNA.
If you pass the exams, you understand the material. If you fail the exams, you don't understand it.
Learning comprehension is the ability to understand what is being learned. There is a difference between hearing or reading and truly understanding the material.
You can put pillow stuffing, cotton balls, or another soft, light material.
A river is heterogeneous, because it has several different substances, such as broadly silt and fish (if you're thinking about it like that) or it is also contained, H20, O2, substances like that so either way it is heterogeneous.
The type of material you use for the project doesn't matter; what truly counts is how well you execute it.
