B. No since rusting is a chemical change it does not follow the law of conservation of mass.
Answer:
hope this helps you
Explanation:
Example 1: A 20 kg object has a velocity of 4.5 m/s in the positive x direction. ... What is the momentum of a 3000 kg truck traveling at 25 m/s? 2. A 1500 kg ferryboat has a momentum of 25000 kg∙m/s. ... *A 0.01 kg bullet has a speed of 700 m/s before it strikes a 0.95 kg wooden block ... We will be going outside so please.
volume is mass divide by density
100/0.8= 125mL
Answer:
[H₂] = 13 M
[N₂] = 12 M
Explanation:
Let´s consider the following reaction at equilibrium.
3 H₂(g) + N₂(g) ⇄ 2 NH₃(g)
To find out the initial concentrations we will use an ICE chart. We recognize 3 stages: Initial, Change and Equilibrium and complete each row with the concentration or change in concentration. We will use letters for the unknown data.
3 H₂(g) + N₂(g) ⇄ 2 NH₃(g)
I a b 0
C -3x -x +2x
E a - 3x b - x 2x
We know that,
[NH₃] = 2x = 5.1 M ⇒ x = 2.6 M
Then,
[H₂] = 5.6 M = a - 3x ⇒ a = 13 M
[N₂] = 9.3 M = b - x ⇒ b = 12 M
