I think it would be D. atoms because they are very tiny but still take up space
Answer:
Option D: Carbohydrates
Explanation:
Carbohydrates are a group of macromolecules that are a vital energy source for the cell, provide structural support to many organisms, and can be found on the surface of the cell as receptors or for cell recognition.
Many minerals may become cements; the most common is silica (generally quartz), but calcite and other carbonates, iron oxides, barite, anhydrite, zeolites, and clay minerals do as well.
Answer:
4 L
Explanation:
using general gas equation formula (in blue pen in attached image),
P1 = 1 atm
V1 = 2.5 L
T1 = 25°C
P2 = 0.5 atm
V2 = x
T2 = 20°C
making V2 subject of the formula (in red pen in attached image),
V2 = 1*2.5*20/25*0.5
= 50/12.5
= 4 L
have a great day!!!
