- Diamond is one form of elemental carbon. An engagement ring contains a diamond weighing 1.25 carats (1 carat = 200 mg). How many atoms are present in the diamond?arrow_forwardThe element silver (Ag) has two naturally occurring isotopes: 109 Ag and 107Ag with a mass of 106.905 u. Silver consists of 51.82% 107Ag and has an average atomic mass of 107.868 u. Calculate the mass of 109Ag.arrow_forwardThese questions concern the work of J. J. Thomson: From Thomson’s work, which particles do you think he would feel are most important in the formation of compounds (chemical changes) and why? Of the remaining two subatomic particles, which do you place second in importance for forming compounds and why? Come up with three models that explain Thomson’s findings and evaluate them. To be complete you should include Thomson’s findings.arrow_forward
- When we refer to doughnuts or cookies, we often refer to 1doz of them, which corresponds to 12. Why is the dozen an inconvenient number when referring to atoms? Why is Avogadros number, 6.0221023, more convenient?arrow_forwardUse a factor derived from the relationships written in Exercise 2.43 and the factor-unit method to determine the following: a.The number of moles of beryllium in a 10.0g sample of beryllium b.The number lead atoms in a 2mol sample of lead c.The number of sodium atoms in a 50.0g sample of sodiumarrow_forwardList some properties of a substance that would lead you to believe it consists of ions. How do these properties differ from those of nonionic compounds?arrow_forward
- A cube of sodium has length 1.25 in. How many atoms are in that cube? (Note: dNa=0.968g/cm3.)arrow_forwardIn Section 1.1 of the text, the concept of a chemical reaction was introduced with the example of the decomposition of water, represented as follows: Use ideas from Dalton's atomic theory to explain how the above representation illustrates the law of conservation of mass.arrow_forwardThe element europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 u and 153Eu has a mass of 152.9209 u. The average atomic mass of europium is 151.96 u. Calculate the relative abundance of the two europium isotopes.arrow_forward
