Answer:
Away from the central sulfur atom.
Explanation:
Answer:
Cr (HSO4)3
Explanation:
its molecular weight is 343.20 g/mol
its molecular formula can also be written as CrH3O12S3
molar mass of Cr (HSO4)3 can be calculated by following method;
atomic mass of Cr = 51.9961 u
atomic mass of H = 1 u
atomic mass of S = 32.065 u
atomic mass of O = 16 u
molar mass of Cr(HSO4)3 = 51.9961+ 1.00784×3 + 32.065×3 + 15.999×12
molar mass of Cr(HSO4)3 =51.9961+3.02352+96.195+ 191.988
molar mass of Cr(HSO4)3 = 343.20 g/mol
Bohr changed the model of the atom by proposing that electrons travelled in circular orbits with specific energy levels.
Answer:
True
Explanation:
Fe³⁺ is an oxidizing agent with E° = +0.77V. Zn metal is a reducing agent with E° = -0.76V. This is a "downhill" reaction, where the oxidizing agent has a higher E° than the reducing agent. Therefore, the reaction is spontaneous.
<u>Answer:</u> The mass of a solute is 35 grams
<u>Explanation:</u>
To calculate the mass percentage of solute, we use the equation:
Mass percent of solute = 10 %
Mass of solution = 350 g
Putting values in above equation, we get:
Hence, the mass of a solute is 35 grams
