Answer:
1. Answer: A, <em>a good sentence</em>
2. Answer: D, <em>fragment</em>
3. Answer: D, <em>fragment</em>
Explanation:
the first sentence is a complete thought, it has a subject and a verb. Both 2 and 3 are fragments, or the beginnings of sentences.
Answer:
Reaction I: Sodium + Aluminum chloride →Sodium chloride + Aluminum
Explanation:
Sodium being more reactive means that it will take the place of aluminium in whats called a displacement reaction and form.
Sodium chloride + Aluminum
Answer:
Kp for the reverse reaction is 76.9
Explanation:
Step 1: Kp at 1000 K = 0.013
Step 2: The balanced equation
2NO (g) + Br2 (g) ⇆ 2NOBr (g)
2NOBr (g) ⇆ 2NO (g) + Br2 (g)
Step 3: Calculate Kp
Kp for the reaction 2NO (g) + Br2 (g) ⇆ 2NOBr (g)
Kp = p(NOBr)²/(pBr2)*(pNO)²
Kp = 0.013
Kp for the reverse reaction 2NOBr (g) ⇆ 2NO (g) + Br2 (g)
Kp' = (pBr2)*(pNO)² /p(NOBr)²
Kp' = 1/Kp = 1/0.013 = 76.9
Kp for the reverse reaction is 76.9
Answer:
Potential
Explanation:
The higher the elevation is the higher the potential energy levels are also the ball is not moving so it is not using kinetic energy.
First you need to count the atoms of each element in the reactantsa and the products. Then use coefficients and place them in front of the compunds until the equations looks fully balanced.
