Answer:
C
Explanation:
1atm=760torr
X=250torr
Cross multiply
760torrX=250torr*atm
Divide both sides by 760torr
X=250torr*atm/760torr
X=0.32895atm
X=0.329atm
Option C is collect
Answer:
A lot of people rejected it outright. Christians were persecuted and killed for their beliefs, and there were no cars, etc for easy transportation. Most people had to walk everywhere since horses and the like were only for the rich and royal. Hope this helps, please give me brainliest :)

Answer:
devices that move a robot's joints
Explanation:
Decreases
Explanation:
The molecules lose potential energy during chemical reactions.
In a chemical reactions, bonds are broken for new ones to be formed. The process of breaking and forming bonds diminishes the potential energy of a bond.
Potential energy is the energy at rest in a body.
In chemicals, potential energy is constituted by the chemical energy stored within the bonds.
When chemical reactions occur, the energy is released often in the form of heat energy. There is always a decrease in potential energy when chemicals reacts together.

Reaction involved in present electrochemical cell,
At Anode: Zn → Zn^2+ + 2e^2-
At cathode: Zn^2+ + 2e^2- → Zn
Net Reaction: Zn + Zn^2+ ('x' m) → Zn^2+(0.1 m) + Zn
Number of electrons involved in present electrochemical cell = n = 2
According to Nernst equation for electrochemical cell,
Ecell = -2.303
= 0.014
Given: T =
, F = 96500 C, R = gas constant = 8.314J/K.mol, [Zn^2+]R = 0.1 m , Ecell = 0.014 v
∴ 0.014 = - 2.303
∴ log
=
= -2.1117
∴ log x = log(0.1) + 2.1117
∴x = 13.09 m
