Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of
Hey there!
Sucrose is C₁₂H₂₂O₁₁.
Find molar mass of sucrose:
C: 12 x 12.01 = 144.12
H: 22 x 1.008 = 22.176
O: 16 x 11 = 176
--------------------------------
342.296 grams
That is the mass of one mole of sucrose.
We have 0.0287.
342.296 x 0.0287 = 9.82
The mass of 0.0287 moles of sucrose is 9.82 grams.
Hope this helps!
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bond. No but they can be compounds
Answer:
Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. ... Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.
