Answer:
6H20 represents six molecules of water
Answer:
1.2*10^24 molecules of CF4
Explanation:
the molar mass of cf4 is 88.0043 g/mol
176/88.0043 = 2 moles of CF4
Then multiply by avogadro's number (6.022*10^23) to get the number of molecules
2*6.022*10^23 = 1.2*10^24 molecules of CF4
Answer:
You should know that density is the relation between, mass and volume as it is described in this equation: d = m/v. As the mass doesn't change in each piece, you will see that volume is less than the original, that's why each piece is 1/3 the density of the original bar or, you can also see, that you have increase by 3, the density original.
Explanation:
Answer : The halogen group of non metals and metalloids these regions will exhibit the trend of having positive and negative oxidation numbers. They are placed on right side of the modern periodic table. The trend of having two oxidation states where one is positive and other is negative in the Groups 13 to 16 of the modern periodic table which contains one or more metalloids, in addition to metals, nonmetals, or both.
