Why are buffers important to living things ?

Chemistry
1 answer:
andrew-mc [135]3 years ago
4 0

Answer:Living systems are very sensitive to pH changes.  Your blood, for example, has a pH of about 7.4.  A rise or drop greater than 0.05 would require hospitalization (alkalosis and acidosis respectively).  A rise or drop of 0.2 is fatal.  If it weren't for the blood-buffering system, then swings this high and greater would be easy to accomplish and maintaining a living system would essentially be impossible.

I hope I answer your question.

1826.5g of methanol (CH3OH), molar mass = 32.0 g/mol is added to 735 g of water, what is the molality of the methane 0.0348 m 1.
Snowcat [4.5K]

Answer:

Molality = 1.13 m

Explanation:

Molality is defined as the moles of the solute present in 1 kilogram of the solvent.

Given that:

Mass of CH_3OH = 26.5 g

Molar mass of CH_3OH = 32.04 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{26.5\ g}{32.04\ g/mol}

Moles\ of\ CH_3OH= 0.8271\ moles

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )

So, molality is:

m=\frac {0.8271\ moles}{0.735\ kg}

<u>Molality = 1.13 m</u>

I can't decide what to ship bacudeku or tododeku ​
iVinArrow [24]

Answer:

I would go with tododeku to leave room for kiribaku but that's my opinion

Just because I ship that doesn't mean i don't secretly ship bakudeku

Explanation:

Bakudeku is a hawt ship and I love it so friggen much, but kiribaku is kinda cute and it got me all mixed up. I'm in a mess as well trying to figure out a solid ship for each character. I'm procrastinating by drawing a bunch of random fanart.

A sample of Ni(CO)4, a toxic transition-metal complex, has 5.23 x 10^24 atoms of carbon. How many atoms of Ni does it contain?
miss Akunina [59]
In Ni(CO)₄ the stoichiometry of Ni to C is 1:4
for every 4 atoms of C is attached to one Ni atom.
this means that if there are 4 atoms of C - 1 atom of Ni
in 5.23 x 10²⁴ atoms of C -1/4 x 5.23 x 10²⁴ atoms of Ni
                                        = 1.3075 x 10²⁴ atoms of Ni
the number of atoms rounded off to the second decimal place = 1.31 x 10²⁴ atoms 
correct answer is E
