Explanation:
Mass of one atom of water = Mass of 1 mole / Avogadro's number
Mass of one atom of water = 18g/mol / 6.022×10²³molecules
Mass of one atom of water = 2.989 × 10^-23 g
Mass of glucose = 180(one molecule)
Mass of 100 molecules of glucose = 180×100 =18000
The correct answer would be option 3. I order for a single displacement to occur there must be a single element and one compound. From then, the single element will then swap places with one of the elements in the compound (or in this case single circle and combined circles). Hope this helped!
Answer:
the total density of the mixture = 3.415 x 10^3 g/mL
Explanation:
given:
density of a substance is 3.4 x 10^3 g/mL
Mixing it with another substance increases the density by 1.5 x 10^1 times.
find:
What is the density of the mixture?
-------------------------------------------------
let density (a) = 3.4 x 10^3 g/mL
density(b) = 1.5 x 10^1 g/mL
since there is no specific density provided for the mixture, we then add both to increase the density,
total density = density(a) + density(b)
total density = 3.4 x 10^3 g/mL + 1.5 x 10^1 g/mL
total density = 3.415 x 10^3 g/mL
therefore,
the total density of the mixture = 3.415 x 10^3 g/mL
Answer:
C
Explanation:
Lime water turns cloudy when it reacts Carbon dioxide
Answer:
Explanation:
Part two of Dalton's theory had to be modified after mass spectrometry experiments demonstrated that atoms of the same element can have different masses because the number of neutrons can vary for different isotopes of the same element. ... Scientists have even developed the technology to see the world on an atomic level!
hoped i helped you :)
