Answer:
Please help!!!
When a piston with a volume of 35 mL is heated from 298 K to 596 Kit
expands. Assuming the pressure on the piston remains constant, determine
the new volume of the cylinder. (round to the nearest whole number)
no
Explanation:
n0? = °^° hhaa jk
Answer:
i think protons and neutrons
Explanation:
im not sure tho
Answer:
1.01 V
Explanation:
From Nernst equation;
Ecell= E°cell- 0.0592/n log Q
Where;
Ecell= observed emf of the cell
E°cell= standard emf of the cell
n= number of moles of electrons transferred
Q= reaction quotient
Q= [Ag^+]^3/[MnO4^-] [H^+]^4
Q= [0.01]^3/[1.20] [1.50]^4
Q= 1.65×10^-7
Ecell= 0.88 - 0.0592/3 log 1.65×10^-7
Ecell= 0.88 - [0.0197×(-6.78)]
Ecell= 0.88 + 0.134
Ecell= 1.01 V
<span>m1v1=m2v2
m2=(m1v1)/v2
Where m is the molarities and v is the volumes
m2=(0.500*25.0)/48.5
m2=12.5/48.5
m2=0.256 M
so it will be A: 0.256 M</span>
