Answer:
As the electrons flow through the wire, <em>electric current </em>is generated around the wire.
Explanation:
The rate of flow of charged particles in a given time is termed as the flow of current. Mostly the charge carriers are termed as electrons in a conductor. So the flow of electrons or movement of charged particles in a given time is the generation of electric current in that current. As the ratio of charge to time at which the charge is moving from one point to another is termed as the current flow in that time.
Thus, in the present case of electrons flowing in that wire will lead to generating of electric current in the opposite direction around the wire.

Answer:
P = 14.1 atm
Explanation:
Given data:
Mass of methane = 64 g
pressure exerted by water vapors = ?
Volume of engine = 24.0 L
Temperature = 515 K
Solution:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O + energy
Number of moles of methane:
Number of moles = mass / molar mass
number of moles = 64 g/ 16 g/mol
Number of moles = 4 mol
Now we will compare the moles of water vapors and methane.
CH₄ : H₂O
1 : 2
4 : 2/1×4 = 8 mol
Pressure of water vapors:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
P = 8 mol × 0.0821 atm.L/mol.K× 515 K / 24.0 L
P = 338.25 atm.L/ / 24.0 L
P = 14.1 atm
Answer: 0.0000332mol
Explanation: 1mole of CCl4 contains 6.02x10^23 molecules.
Therefore, X mol of CCl4 will contain 2 x 10^19 molecules i.e
Xmol of CCl4 = 2 x 10^19/ 6.02x10^23 = 0.0000332mol
