Photosinthisises equation is carbon dioxide + water ⇒ glucose (suger) + water
the light is needed to react with the CO² to create the oxygen needded<span />
The volume of the balloon when the mass of oxygen gas is decreased to 50g is 50L.
We will use the ideal gas equation-
<u>PV=nRT</u>
P=Pressure
V=volume
n=no. of moles
T=temperature
In this question temperature and pressure will remains constant then the above equation can be rewritten as-

where V1= initial volume of the balloon
V2= volume of the balloon when the mass of oxygen gas is decreased to 50g
now, substitute the values in the above equation-
100/3.12=V2/1.56
hence, the volume of the balloon when the mass of oxygen gas is decreased to 50g is 50L.

Answer: a, b, d
Explanation:Physical property are measurable (or perceived) property of something observable without having to change the composition or identity of that thing.
Examples of physical properties in the context included in the question are the following: • Temperature • Solubility • Resistivity • Conductivity • Density
Answer:
Cell
Explanation: An atom is smaller, but isn't a living organism, so the second smallest would be cell.
