The statement of the combined gas law for a fixed amount of gas is,
PV/T = constant
Here, the units of pressure and volume must be consistent and the temperature must be the absolute temperature (Kelvin or Rankine).
0.65 atm is equivalent to 494 mmHg
Using the equation:
(755 x 500) / (27 + 273) = (494 x V) / (-33 + 273)
V = 3396 ml = 3.4 liters
I think that this would be the excretory system.
The Digestive systems breaks down food into nutrients the body can use
The respiratory system brings in oxygen and removes carbon dioxide
The excretory system removes waste products from the body
The nervous system controls all other systems and processes information
According to Henderson–Hasselbalch Equation,
pH = pKa + log [Lactate] / [Lactic Acid]
As,
Ka of Lactic Acid = 1.38 × 10⁻⁴
pKa = -log Ka
pKa = -log 1.38 × 10⁻⁴
pKa = 3.86
So,
pH = 3.86 + log [0.10] / [0.13]
pH = 4.74 + log 0.769
pH = 4.74 - 0.11
pH = 4.63
Answer:
Pb(s), Sn(s), Cu(s), Fe(s), Al(s)
Explanation:
The specific heat (Cp) of a substance is defined as the heat required per unit of mass to raise the temperature in 1°C.
Thus, the substance with the larger Cp will need more energy to reach a temperature and vice versa.
Based on this information, the fastest metal to reach 80°C will be Pb -lowest Cp-, then Sn, Cu, Fe and Al.
From 1 to 5:
<em>Pb(s), Sn(s), Cu(s), Fe(s), Al(s)</em>
