Answer:
30.84atm
Explanation:
Using the ideal gas formula:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821Latm/molK)
T = temperature (K)
According to the provided information in this question,
P = ?
V = 2.3 L
n = 3 mol
T = 15°C = 15 + 273 = 288K
Using PV= nRT
P = nRT/V
P = (3 × 0.0821 × 288) ÷ 2.3
P = 70.9344 ÷ 2.3
P = 30.84atm
-1.1 Volt
this is called a standard Zinc-Copper cell potential
<u>Given that </u>–
<u>We know that</u> –
Then –
Now the number of moles of KOH need to ensure that concentration of Hydroxide anions is equal to –
Volume of the solution contains the need number of moles of Hydroxide anions –

Answer:
A chemical reaction is a rearrangement of atoms which turn one or more compounds into new compounds. Equations and models may describe all of the chemical reactions. ... If atoms detach from each other and recombine into various types of atoms, we conclude that there has been a chemical reaction.
