Answer:
P = 1.21atm
Explanation:
Using PV = nRT, moles of both syringes is:
Moles CO:
n = PV / RT
n = 1.5atm*0.610L / 0.082atmL/molK*310K
n = 0.0360 moles
Moles N₂:
n = PV / RT
n = 3.5atm*0.520L / 0.082atmL/molK*325K
n = 0.0683 moles.
As in the container you mix both gases, moles in the container are:
n = 0.0360 + 0.0683 = <em>0.1043 moles</em>
Conditions of the container are:
V = 2.00L; T = 273.15K + 10°C = 283.15K; n = 0.1043 moles.
Thus, pressure is:
P = nRT / V
P = 0.1043mol*0.082atmL/molK*283.15K / 2.00L
<h3>P = 1.21atm</h3>

Answer:
b. Lithium
Explanation:
<u>Lithium-ion batteries (LIB) is a rechargeable battery</u>. It was first proposed by M stanley Whittingham in 1970s. These kind of batteries are commonly used in electrical vehicles and portable electronics. It also have military , naval and aerospace applications.
<u>
In LIB, the lithium ions move from the negatively charged electrode to the positively charged electrode during the discharge process and move in the reverse direction when the during the charging process.</u> The battery uses an intercalated lithium compound is used to form anode and graphite is used to form cathode.
<u>Thus, Lithium is oxidized/reduced in a lithium ion battery.</u>
PH is a simplified observation of the acidity of a solution, defined as the -log [H+] (negative logarithm of the hydrogen concentration).
-log[10^-4] = 4
The pH of this solution is 4.
