A changing magnetic field produces an electric field with open loop field lines.

Chemistry
1 answer:
Dimas [21]4 years ago
8 0

Answer:

True

Explanation:

A changing magnetic field induces a current in a conductor. For example, if we move a bar magnet near a conductor loop, a current gets induced in it.

The densevapor iodinee heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid .
erma4kov [3.2K]

Explanation:

When iodine heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid. Reaction equation for the same is as follows.

       IF_{7} + 6H_{2}O \rightarrow H_{5}IO_{6} + 7HF

As it is given that there are 3.72 \times 10^{-2} moles of iodine heptafluoride are present. Molar mass of IF_{7} is 259.9 g/mol. Molar mass of HIO_{4} is 227.94 g/mol and molar mass of HF is 20.01 g/mol.

Now, according to the reaction equation 3.72 \times 10^{-2} M IF_{7} gives 3.72 \times 10^{-2} M H_{5}IO_{6}.

Also, the volume is given as 795 ml or 0.795 L (as 1 mL = 0.001 L).

Hence, calculate the concentration of H_{5}IO_{6} into the solution as follows.

              Concentration = \frac{\text{no. of moles}}{volume}

                                      = \frac{3.72 \times 10^{-2}}{0.795 L}

                                      = 4.7 \times 10^{-2} mol/L

or,                                   = 0.047 M

Now, as 1 mol of IF_{7} produces 7 mol HF. So, 7 \times 3.72 \times 10^{-2} = 26.04 \times 10^{-2} M HF.

Therefore, concentration of HF will be calculated as follows.

             Concentration of HF = \frac{0.2604}{0.795}

                                              = 0.33 M

Thus, we can conclude that concentration of periodic acid is 0.047 M and concentration of hydrofluoric acid is 0.33 M.

Why is it not important to accurately measure the amount of 6 M HCl you place in your eudiometer tube
MissTica

It is not important to accurately measure the amount of HCl placed in the eudiometer tube since HCl will be added in excess to react with all the moles of Mg.

In gas stoichiometry, through the method of displacement of a liquid (generally water), the gaseous byproduct is collected inside a long, thin graded glass tube called a eudiometer.

If we consider a reaction between Magnesium and Hydrochloric acid to give a product known as magnesium chloride and hydrogen gas, we can have the chemical equation represented as:

\mathbf{Mg_{(s)} + 2 HCl _{(aq)} \to MgCl_{2(aq)} + H_{2(g)}}

From the above reaction, for each mole of Magnesium taking place in the reaction, 1 mole of hydrogen gas is also produced.

Thus, we can have a prediction that HCl can always be added in excess in order for us to react to all the moles of solid magnesium, hence, it is not important to measure the moles of HCl since it will be added in excess.
