Correct answer: Galvanic cell
Reason:
Following are the differences between Galvanic cell and electrolytic cell:
1. <span>Galvanic cell converts chemical energy into electrical energy , on other hand <span>electrolytic cell converts electrical energy into chemical energy.
2. In galvanic cell, </span></span><span>redox reaction is spontaneous and is responsible for the production of electrical energy. in electrolytic cell, t<span>he redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
Thus, galvanic cell </span></span><span>refers to an electrochemical cell that produces an electric current</span>
Answer:
<em>Conduction</em>
Explanation:
Conduction is heat transfer between two objects that are touching each other. When two objects touch and one has a higher temperature than the other; heat is transferred to the object with the lower temperature. ... In radiation, heat is transferred from one object to another by electromagnetic waves of energy. <em>Edit </em><em>:</em> <em>Please </em><em>mark </em><em>brainliest</em><em> </em><em>if </em><em>it </em><em>helped,</em><em> </em><em>thanks.</em>
Answer:
The temperature is 288, 88K
Explanation:
We use the formula PV= nRT:
T= PV/nR
T= 0,987 atm x12 L/0,50 mol x 0,082 l atm/K mol
<em>T=288,88K</em>
volume of H₂O = 7.2 L
Explanation:
The combustion reaction of methane (CH₄):
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Now we calculate the number of moles of methane using the following formula:
number of moles = volume / 22.4 (L/mole)
number of moles of CH₄ = 3.6 / 22.4
number of moles of CH₄ = 0.16 moles
Taking in account the chemical reaction, we devise the following reasoning:
if 1 mole of CH₄ produce 2 moles of H₂O
then 0.16 moles of CH₄ produce X moles of H₂O
X = (0.16 × 2) / 1 = 0.32 moles of H₂O
And now we can calculate the volume of water (H₂O) produced by the reaction:
number of moles = volume / 22.4 (L/mole)
volume = number of moles × 22.4 (L/mole)
volume of H₂O = 0.32 × 22.4
volume of H₂O = 7.2 L
