<span>a. True The body's pH level is critical to the functioning of the bodies cells. A pH in the range of 7.35 to 7.45 is considered "normal", although a large number of doctors get nervous if the pH is towards the outer edges of that range. If your pH gets down to 6.9, you'll be a coma. At 6.8, you're dead. And if the pH goes up to 7.8, you're also dead.</span>

Question 1
OLga [1]

Answer: 7 atm

Explanation:

According to Dalton's Law, the total pressure is the sum of all the individual gas pressures

Hence, Ptotal = P1 + P2 + P3

Since, Gas A = 2 atm

Gas B = 1 atm

Gas B = 4 atm

Ptotal = (2 + 1 + 4) atm

Ptotal= 7 atm

Thus, the total pressure of the gas mixture is 7 atmosphere.

Another chemistry question i’m not good at this at all:( has me stressed
adoni [48]

Answer:

Average atomic mass = 15.86 amu.

Explanation:

Given data:

Number of atoms of Z-16.000 amu = 205

Number of atoms of Z-14.000 amu = 15

Average atomic mass  = ?

Solution:

Total number of atoms = 205 + 15 = 220

Percentage of Z-16.000 = 205/220 ×100 = 93.18%

Percentage of Z-14.000 = 15/220 ×100 = 6.82 %

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (93.18×16.000)+(6.82×14.000) /100

Average atomic mass =  1490.88 + 95.48 / 100

Average atomic mass =  1586.36 / 100

Average atomic mass = 15.86 amu.
