Alexus [3.1K]3 years ago
4 0

Answer: D) All of the above

Explanation:

The sources of errors in the kinetic experiment are depends upon the tools, due to some personal errors and also due to some methodological problem. As, experimental error during kinetic study is due to the difficulty to characterize the experimental errors depend on reaction conditions. The behavior of the experimental errors are depend on specific feature of the experiment systems.

Calculate the percentage of calcium in calcium chlorate
givi [52]

Answer:

19.4%

Explanation:

Calcium Chlorate is Ca(ClO3)2

Now calculate the molar mass of Ca(ClO3)2

Ca = 40.1

Cl = 35.5

O = 16.0

But they are two chlorine atoms and six oxygen atoms. So you do this:

40.1 + 35.5(2) + 16.0(6) = 207.1 grams

Now find the molar mass of just calcium.

There is only one calcium atom.

So you do this.

40.1(1) = 40.1

Now divide the molar mass of calcium by the molar mass of calcium chlorate.

40.1 / 207.1 = 0.1936

0.1936 rounds to 0.194

Now multiply 0.194 * 100 and you will get 19.4

So the final answer is 19.4%.

Hope it helped!

How many moles of hypomanganous acid, H3MnO4, are contained in 22.912 g?
harkovskaia [24]

Answer:

0.188mol

Explanation:

Using the formula as follows:

mole = mass/molar mass

Molar mass of hypomanganous acid, H3MnO4 = 1(3) + 55 + 16(4)

= 3 + 55 + 64

= 122g/mol

Mass of H3MnO4 is given as 22.912 g

Hence;

moles = 22.912 ÷ 122

number of moles = 0.188mol
