Answer:2155 J
Explanation:
Given
Change in Internal energy 
i.e. decrease in Internal Energy
Heat added to system 
According First law for a system
Thus 2155 J of work is done by system

Answer:
3.46 A
Explanation:
The force (F) exerted on a wire of a particular length (L) carrying current (I) through a magnetic field (B) at an angle (θ) to the magnetic field is given as
F = (B)(I)(L) sin θ
F = 3.13 N
B = 0.360 T
I = ?
L = 2.50 m
θ = 79°
3.13 = (0.360 × I × 2.5 × sin 79°)
0.8835 I = 3.13
I = 3.54 A
But this is the resultant current in this magnetic field.
Since the two wires are conducting current in opposite directions,
Resultant current = 7 - (current in the other wire)
Current in the other wire = 7 - 3.54 = 3.46 A
P₄ + 3O₂ ⟶ 2P₂O₃
Explanation:
A balanced equation is any equation that complies with the law of conservation of matter and mass.
The law of conservation of matter states that "in a chemical reaction, matter is neither created nor destroyed but simply rearranges. ".
This suggests that the total number of atoms on both reactant and product sides must be the same in a balanced chemical equation. Also, the same atoms are found on both sides of a chemical equation with no additional or external species.
Now let us check if the equation is conserved:
P₄ + 3O₂ ⟶ 2P₂O₃
Atoms reactant product
P 4 4
O 6 6
We see that we have equal number of atoms on both sides. The equation is balanced.
