I’m not sure but I think it’s 2-7-4 because the numbers should still add up to 13.(hope it helped)
Explanation:
Mike drives his car 60 km in 55minutes. What is its average speed in kilometers per hour ? A train travels 120 km in 2 hours and 30 .
Answer:
The answer to your question is Volume = 0.7 l
Explanation:
Data
Volume 1 = V1 = 0.746 l
Pressure 1 = P1 = 94.6 kPa
Volume 2 = V2 = ?
Pressure 2 = 101.33 kPa
Process
To solve this process use Boyle's law.
P1V1 = P2V2
-Solve for V2
V2 = P1V1/P2
-Substitution
V2 = (94.6 x 0.746) / 101.33
-Simplification
V2 = 70.57 / 101.33
-Result
V2 = 0.696 l ≈ 0.7 l
Sweating is your body releasing water to cool it’s self down. When doing an activity the water in ur body warms up. And is then released to stop from overheating
Answer:
D. 5.0
Explanation:
Step 1: Write the balanced equation at equilibrium
2 NO₂(g) ⇄ N₂O₄(g)
Step 2: Calculate the concentration equilibrium constant
The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
Kc = [N₂O₄]/[NO₂]² = 0.2 / 0.2² = 5
