As pressure decreases so does boiling point. One reason astronauts wear space suits in space is because of the decreased pressur
PilotLPTM [1.2K]
First, we need to be aware that our blood is also  a form of liquid.
So, when the astronaut is placed in within the environment that has decreased pressure,  the temperature inside the astronaut's body will definitely increase but it won't cause the boiling effect like in water (it won't even break the arteries). But it could endanger the astronaut's life because it makes the blood unable to circulate properly due to unstable blood pressure

What could happen to the amount of greenhouse gases in the atmosphere if oceans continue to warm? How could this impact global c
My name is Ann [436]

The solubility of gas in water is inversely proportional to the temperature. That means cool waters can hold more gases than hot waters. So when the oceans continue to warm all the green--houses gases present in oceanic waters will be released into to the atmosphere. This would further lead to the heating up of the planet. The global climate would keep changing and the temperature of the planet would increase further. Therefore, when the oceans continue to warm the amount of green-house gases  cannot be sequestered by the oceans (as the temperatures are high) and so this would further enhance the greenhouse effect.

What is the net charge of the peptide arg-ala-phe-leu at ph 8?
adell [148]
The structure of this oligopeptide is attached:

It consists of arginine - alanine - phenylalanine and leucine

From the picture we can see that N terminus charge is +1
Also Arginine is considered as basic amino acid with charge +1
C terminus charge is -1

At pH = 8, the whose pKa are less than pH will be deprotonated and the net charge will be +1 

So the net charge of this oligopeptide is +1 at pH = 8

What is the gram formula mass of Ca3(PO4)2
Georgia [21]
Mass Molar of Ca_{3} (PO_4)_2
Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of Ca_{3} (PO_4)_2 = 120 + 62 + 128 = 310 g/mol

Therefore: <span>What is the gram formula mass of Ca3(PO4)2 ?
</span>Answer: 310 grams
