A(g) + B(g) → 3C(g)
This is because the volume of gas after reaction is greater than that before the reaction (because there are more moles in the product than in the reactants) so the system's boundary will have to expand in order to maintain constant pressure; this means that the system will do work on its surroundings.
Answer:
τ = - (8.1 N-m) i - (10.8 N-m) j - (8.1 N-m) k
Explanation:
Given
r = (0 m) i + (0.9 m) j - (1.2 m) k
F = (9 N) i + (0 N) j - (9 N) k
We can apply
τ = r x F
τ = ((0 m) i + (0.9 m) j - (1.2 m) k) x ((9 N) i + (0 N) j - (9 N) k)
⇒ τ = - (8.1 N-m) i - (10.8 N-m) j - (8.1 N-m) k
Decomposition. The compound element is breaking down into 2H2 and O2.
Answer:
B, C, and D
Explanation:
A is the only one in which two components are being combined. The point is to separate the mixture, so that is the only one that would not apply.
Create and use more electricity then previously used before. A lot of power is created by burning fossil fuels, the burning of them will be increased so more is needed to give power to everyone.
