Answer:
v2 = 100 Ml OR 0.1 Liters
Explanation:
(400 Ml) (10 atm) = (v2) (40 atm)
4000 = 40v2
100 Ml = v2
Liters = ml / 1000
Liters = 100 / 1000
Liters = 0.1
Answer:
Time take to deposit Ni is 259.02 sec.
Explanation:
Given:
Current
A
Faraday constant

Molar mass of Ni

Mass of Ni
g
First find the no. moles in Ni solution,
Moles of Ni 
mol
From the below reaction,
⇆ 
Above reaction shows "1 mol of
requires 2 mol of electron to form 1 mol of
"
So for finding charge flow in this reaction we write,

Charge flow
C
For finding time of reaction,

Where
charge flow


sec
Therefore, time take to deposit Ni is 259.02 sec.
Answer is: both reactions are exothermic.
<span>In exothermic reactions, heat is released and enthalpy of reaction is less than zero (as it show second chemical reaction).
According to Le Chatelier's principle when the reaction
is <span>exothermic heat is included as a
product (as it show first chemical reaction).</span></span>
Answer:

Explanation:
Given
485 L
Required
Determine the measurement not equal to 485L

<em>From standard unit of conversion;</em>
1 KL = 1000 L
<em>Multiply both sides by 485</em>


<em>Divide both sides by 1000</em>

---- This is equivalent
---------------------------------------------------------------------------------------------

<em>From standard unit of conversion;</em>
1000 mL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form

Hence;
is not equivalent to 485L
---------------------------------------------------------------------------------------------

<em>From standard unit of conversion;</em>
100 cL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form
---- This is equivalent
---------------------------------------------------------------------------------------------
μL
<em>From standard unit of conversion;</em>
1000000 μL = 1 L
<em>Multiply both sides by 485</em>


Convert to standard form
---- This is equivalent
From the list of given options;
is not equivalent to 485L
