How much is each gallon or how far are you going is the question you should be asking
Answer:
The answer is "2.459".
Explanation:
The cell potential or emf norm = oxidation pot. of anode -oxidation pot. of cathode
When the pot oxidizer is the opposite of a red pot size it's been transformed to either the redox reaction so that anode was its higher oxide pot material that means (AL) so,
Answer:
(a) 0 J
(b) -9.5 J
(c) -18 J
Explanation:
A gas expands in volume from 26.7 to 89.3 mL at constant temperature. The change in volume is:
ΔV = 89.3 mL - 26.7 mL = 62.6 mL = 0.0626 L
The work done (w) can be calculated using the following expression.
w = - P × ΔV
where,
P is the pressure
<em>(a) against a vacuum (P = 0)</em>
w = - P × ΔV = - 0 atm × 0.0626 L = 0 atm . L = 0 J
<em>(b) against a constant pressure of 1.5 atm</em>
w = - P × ΔV = - 1.5 atm × 0.0626 L × (101.3 J/1 atm.L) = -9.5 J
<em>(c) against a constant pressure of 2.8 atm</em>
w = - P × ΔV = - 2.8 atm × 0.0626 L × (101.3 J/1 atm.L) = -18 J
Answer:
0.108
Explanation:
You use the formula Q =mco
M is mass
Q is th heat release
C is specific heat
O is the temperature change
Substitute what you have and what you get in the information in the equation then you will get your answers
