Pi bonds<span> are usually </span>weaker than sigma bonds<span>. Quantum mechanics says this is because the orbital paths are parallel so there is much less overlap between the p-orbitals.
It's basically depend on the formation of these bonds.

Answer:
The answer is
<h2>110.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of rock = 5.8 g/mL
volume = final volume of water - initial volume of water
volume = 12.4 - 10.5 = 1.9 mL
The mass of the rock is
mass = 5.8 × 1.9
We have the final answer as
<h3>110.2 g</h3>
Hope this helps you
Answer:
Explanation:
The easy way is knowing that all gases basically are 22.4 L/mol at SATP.
There fore 3.45 L/22.4 L/mol =0.154 mol
Or use PV=nRT
n=(1 atm)(3.45L)/(273 K)(0.82 L atm)/(mol K) =0.154 mol
same answer
Answer:
Kelvin is considered to be the best scale for measuring temperature for two reasons: 1, Because the Kelvin scale defines what we mean by temperature. Other scales are now defined in terms of the Kelvin scale
