Hydrochloric acid and sodium hydroxide neutralise each other and the pH resulting solution will be 7.
Scientists are able to understand Earth's interior by studying seismic waves. These are waves of energy that travel through Earth, and they move similarly to other types of waves, like sound waves, light waves, and water waves.
Moles of Oxygen they took in : C. 2.42
<h3>Further explanation</h3>
The gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 l.atm / mol K
T = temperature, Kelvin
P=1000 kPa
V = 6 L
T = 298 K
moles of Oxygen :
