"calculate the h+ in a solution that has a ph of 8.73"
alexdok [17]
The  H+   in  a  solution  that  has  a Ph  of  8.73   is   calculate    as  follows

Ph is always =   -  log  (H+)

H+  =    10^-Ph

H+  is  therefore  =  10 ^-  8.73
H+  =  1.86  x10^-9  M

The volume of a bubble that starts at the bottom of a lake at 4.55°C increases by a factor of 8.00 as it rises to the surface wh
Masja [62]

Answer:

The depth of the lake is 67.164 meters.

Explanation:

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas in bubble= ?

P_2 = final pressure of gas = 0.980 atm

V_1 = initial volume of gas = V

V_2 = final volume of gas = 8.00 × V

T_1 = initial temperature of gas = 4.55^oC=273.15+4.55=277.7 K

T_2 = final temperature of gas = 18.05^oC=273.15+18.05=291.2 K

Now put all the given values in the above equation, we get:

\frac{P_1\times V}{277.7 K}=\frac{0.980 atm\times 8.00\times V}{291.2 K}

P_1=7.476 atm

pressure of the gas in bubble initially is equal to the sum of final pressure and pressure exerted by water at depth h.

P_1=P_2+h\rho\times g

Where :

\rho = density of water = 1.00 g /cm^3=1000 g/m^3

g = acceleration due gravity = 9.8 m/s^2

7.476 atm=0.980 atm +h\rho\times g

6.496 atm=h\rho\times g

6.496 \times 101325 Pa=h\1000 g/m^3\times 9.8 m/s^2

h = 67.164 m

The depth of the lake is 67.164 meters.

What type of metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges?.
Mariulka [41]

Hydrothermal metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges

Hydrothermal metamorphism is most common along mid-ocean ridge spreading centers, where warm seawater percolates through hot, cracked basalt. Metamorphism of basalt occurs as a result of chemical interactions between hot saltwater and basalt. On continents, crustal rocks can be metamorphosed by invading, hot fluids associated with igneous intrusions, resulting in hydrothermal metamorphism.

The interaction of a rock with a high-temperature fluid of changing composition results in hydrothermal metamorphism. The compositional mismatch between an existing rock and the entering fluid causes a series of metamorphic and metasomatic processes.

Hydrothermal metamorphism changes Mg-Fe-rich hydrous minerals like talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals. Hydrothermal metamorphism is frequently responsible for the formation of rich ore deposits.
