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.

Based on the scientific sources you found, did you think one person’s points were more scientifically valid than the other’s

DanielleElmas [232]

What is research? Depending on who you ask, you will likely get very different answers to this seemingly innocuous question. Some people will say that they routinely research different online websites to find the best place to buy goods or services they want. Television news channels supposedly conduct research in the form of viewer polls on topics of public interest such as forthcoming elections or government-funded projects. Undergraduate students research the Internet to find the information they need to complete assigned projects or term papers. Graduate students working on research projects for a professor may see research as collecting or analyzing data related to their project. Businesses and consultants research different potential solutions to remedy organizational problems such as a supply chain bottleneck or to identify customer purchase patterns. However, none of the above can be considered “scientific research” unless: (1) it contributes to a body of science, and (2) it follows the scientific method. This chapter will examine what these terms mean
