Answer:
Robert Boyle discovered Boyle’s law, which Denotes that the volume and pressure of a gas are proportionally related. He dispelled the four-element theory of Aristotle, which states that everything is made up of earth, water, air, and fire. He also dispelled the three-principle theory of Paracelsus.
Explanation:
Answer:
Temperature was independent
Reaction rate is dependent
Other factors are constant
n=PV/RT
convert:
740 torr to atm (1 atm=760 torr)
50 degree celsius to kelvin ( degree celsus +273= kelvin)
n=(0.9737 atm)(12.5L)÷(0.08206 L atm mol ⁻¹k⁻¹) (323 K)
n=0.4592 mols×22.4 L/1 mol. (22.4 L STP= 1 mol)
=10.286 L at STP
it could be this
Answer:
Sand: 28°C, 27°C, 26°C
Potting soil: 33°C, 29°C, 31°C
Mixture: 29°C, 29°C, 22.5°C.
Explanation:
Reaction is NaHCO3 + HCL = H2CO3 + NaCl
the ratios are 1:1
the 8 moles of HCl are in excess
so if you use 4 moles of NaHCO3 then you will obtain 4 moles of carbonic acid
