Naturally occurring zirconium exists are five isotopes. axe with a mass of 89.905 u(51.45%); Zr with a mass of 90.906 u (11.22%)
Anton [14]
Isotope 1: 89.905 * 51.45 = 4625.61225 / 100 = 46.2561225
Isotope 2: 90.906 * 11.22 = 1019.96532 / 100 = 10.1996532
Isotope 3: 91.905 * 17.15 = 1576.17175 / 100 = 15.7617075
Isotope 4: 93.906 * 17.38 = 1632.08628 / 100 = 16.3208628
Isotope 5: 95.908 * 2.08 = 268.5424 / 100 = 2.685424

46.2561225 + 10.1996532 +  15.7617075 + 16.3208628 + 2.685424 = 91.22377
actual mass Zr = about 91.22

A solution is made by mixing 34.5 g of sugar with 75.0 g of water. What is the mass percent of sugar in this solution?
lubasha [3.4K]

the mass percent of sugar in this solution is 46%.

Answer:

Solution given:

mass of solute=34.5g

mass of solvent=75g

mass percent=\frac{mass\:of\:solute}{mass\:of \:solvent}*100\%

=\bold{\frac{34.5}{75.0}*100\%=46\%}

Read the following chemical equation: Ti + 2Cl2 → TiCl4 Which statement best identifies and describes the reducing agent in the
goldenfox [79]

Answer: Ti is the reducing agent because it changes from 0 to +4 oxidation state.

Explanation:

  • Firstly, we need to identify the reducing agent and the oxidizing agent.
  • The reducing agent: is the agent that has been oxidized via losing electrons.
  • The oxidizing agent: is the agent that has been reduced via gaining electrons.
  • Here, Ti losses 4 electrons and its oxidation state is changed from 0 to +4 and Cl₂  gains one electron  and its oxidation state is changed from 0 to -1.
  • So, Ti is the reducing agent because its oxidation state changes from  0 to +4.
  • Cl₂ is the oxidizing agent because its oxidation state changes from 0 to -1.
  • Thus, The right answer is Ti is the reducing agent because it changes from 0 to +4 oxidation state.
