There are some things such as matter, constituents, chemicals, compounds.
Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
Answer:
It helps identify trends and group elements with similar properties.
Explanation:
Arranging the elements according to the atomic mass wouldn't help us have groups and periods with predictable properties that we can have when arranging it according to atomic number. Don't forget that isotopes have different masses.
Mass of oxygen : 54 g

Conservation of mass applies to a closed system, where the masses before and after the reaction are the same
Reaction
![\tt C+O_2\rightarrow CO_2](https://tex.z-dn.net/?f=%5Ctt%20C%2BO_2%5Crightarrow%20CO_2)
mass before reaction = mass after reaction
mass C + mass O₂= mass CO₂
![\tt 18~g+mass~O_2=72~g\\\\mass~O_2=72-18=\boxed{\bold{54~g}}](https://tex.z-dn.net/?f=%5Ctt%2018~g%2Bmass~O_2%3D72~g%5C%5C%5C%5Cmass~O_2%3D72-18%3D%5Cboxed%7B%5Cbold%7B54~g%7D%7D)
Answer:
infared light.
Explanation:
Infared cameras are sensitive to wavelengths of light out side of our visible light spectrum. They are sensitive to wavelengths from about 1,000nm to 14,000 nm. Visible light ranges from about 400-700nm.
