Answer:
The statement describes a process involved in the evolution of Earth’s early atmosphere would be:
Cyanobacteria transformed carbon dioxide in the atmosphere into oxygen during photosynthesis
Hope it helped :3
Answer: PV = nRT
A gas at STP... This means that the temperature is 0°C and pressure is 1 atm.
R is the gas constant which is 0.08206 L*atm/(K*mol)
Rearranging for volume
V = nRT/P
The temperature and number of moles are held constant. This means that this uses Boyle's Law. (The ideal gas law could be manipulated to give us this result when T and n are held constant.)
PV = k
where k is a constant.
This means that
P₁V₁ = k = P₂V₂
P₁V₁ = P₂V₂
(1 atm) * (1 L) = (2 atm) * V₂
V₂ = 0.5 L
The new volume of the gas is 0.5 L.
Explanation:
The molarity of acetic acid is calculated as follows
find the number of moles of NaOH = molarity x volume
= 17x0.2 = 3.4 moles
write the equation for reaction
CH3COOH + NaOH = CH3COONa +H2O
since ratio is be of CH3COOH to NaOH is 1:1 the moles of CH3COOH is therefore = 3.4 moles
therefore the molarity = moles/volume
= 3.4 /10 = 0.34 M
