Answer:

Nearly all of the water astronauts drink and shower with comes from their urine and sweat. Storage is hard to come by aboard the International Space Station. Even if a rocket had room to ferry thousands of pounds of water and oxygen to supply a six-month mission, you'd struggle to find anywhere to stash it.

Answer:

Astronauts drink water that comes from the ambient cabin's humidity, which is eventually condensed and returned to the water supply. The water is filtered from recycled shower water, astronaut sweat and urine.

The H⁺ concentration in an aqueous solution at 25 °C is 9.1 × 10⁻⁴. What is [OH⁻]?

Vinvika [58]

Steps:-

First we calculate pH then pOH then [OH-]

$\\ \tt\rightarrowtail pH=-log[H^+]$

$\\ \tt\rightarrowtail pH=-log[9.1\times 10^{-4}]$

$\\ \tt\rightarrowtail pH=-log9.1-log10^{-4})$

$\\ \tt\rightarrowtail pH=0.95+4$

$\\ \tt\rightarrowtail pH=4.95$

Now

$\\ \tt\rightarrowtail pH+pOH=14$

$\\ \tt\rightarrowtail pOH=14-4.95$

$\\ \tt\rightarrowtail pOH=9.05$

$\\ \tt\rightarrowtail -log[OH^-]=9.05$

$\\ \tt\rightarrowtail log[OH^-]=-9.05$

$\\ \tt\rightarrowtail OH^-=10^{-9.05}$

$\\ \tt\rightarrowtail OH^-=8.91\times 10^{-4}$

professor190 [17]

Answer:

<u> Translation:</u>

Classify the following elements into metals, nonmetals, metalloids, or gases, noble : fluorine, sulfur, nitrogen, chlorine, magnesium, helium, sodium, bromine, silicon, tellurium.

Metals: magnesium and sodium.
Nonmetals: fluorine, chlorine, bromine, sulfur and nitrogen.
Metalloids: silicon and tellurium.
Noble gases: helium.

Explanation:

Metals: They occupy the left and central areas of the Periodic Table; therefore, they constitute a majority group of the elements.

Nonmetals: They are located in the upper right region of the Periodic Table.

Within the Periodic Table, the metalloids lie diagonally from boron to polonium. Items above on the right are nonmetals, and items below on the left are metals.

The noble gases are located in group 18 of the Periodic Table.
