Answer:
The balloon will occupy a volume of 6.48 L
Explanation:
<u>Step 1: </u>Data given
internal pressure = 1.00 atm
volume = 4.50 L
Temperature = 20.0 °C
<u>Step 2:</u> Calculate new volume via the ideal gas law
P*V = n*R*T
(P1*V1)/ T1 = (P2*V2)/T2
⇒ with P1 = 1.00 atm
⇒ with V1 = 4.50 L
⇒ with T1 = 20.0 °C = 293 Kelvin
⇒ with P2 = 0.600 atm
⇒ with V2 = TO BE DETERMINED
⇒ with T2 = -20°C = 253 Kelvin
(1.00atm * 4.50 L)/293 Kelvin = (0.600 atm*V2) / 253 Kelvin
0.01536 = 0.00237 V2
V2 = 6.48 L
The balloon will occupy a volume of 6.48 L

The cellular macromolecules that are referred by the description above are the LIPIDS. The complement pathway system is a constituent of the natural immunity and this provides us a natural defense against infection. In the complement pathway of the immune system, the macromolecules that make this up are the lipids.
Answer and Explanation:
A chemical formula is composed by chemical symbols (in letters, which indicate the chemical elements) and subscripts (numbers). For example, let see the chemical formula for <em>carbon dioxide</em>:
CO₂
The letters C and O are the chemical symbols for the elements carbon (C) and oxygen (O). The number 2 in subscript indicates that there are 2 atoms of O per molecule. The subscript 1 is generally not indicated in chemical formulae, so it is assumed that the number of atoms of C is 1.
Summarizing, the chemical formula CO₂ indicates us that the molecule if formed by 1 atom of the element carbon (C) and 2 atoms of the element oxygen (O).
