Answer:
A) 1.68 L
Explanation:
- Charles’ Law states that: at constant pressure, the volume is directly proportional to the temperature of the gas.
- It can be expressed as: V₁T₂ = V₂T₁,
V₁ = 1.2 L, T₁ = 175.0 K, V₂ = ??? L, T₂ = 245.0 K.
∴ V₂ = V₁T₂/T₁ = (1.2 L)(245.0 K)/(175.0 K) = 1.68 L.
It is amu or dalton both meet the same definition.
The maximum number of D orbitals in a principal energy level is 5.
Answer:
3.9 laps
Explanation:
Step 1: Given data
Length of the hamster track (L): 255 cm
Total distance to be run (D): 10 m
Step 2: Convert "D" to centimeters
We will use the relationship 1 m = 100 cm.
10 m × (100 cm/1 m) = 1.0 × 10³ cm
Step 3: Calculate the number of laps (n) that the hamster should run
We will use the following expression.
n = D/L
n = 1.0 × 10³ cm/255 cm
n = 3.9
