Answer:The lone pair of electrons takes up more space than a regular bonding pair since it it is not confined to be between two atoms, so it adds coulombic repulsion to the bonding pairs and compresses the angle. Therefore, the bond angle is less than the standard 109.5∘ . It is actually 97.7∘
Answer:
false
Explanation:
the magnetic domains in the area around a magnet where the force acts.
An Atom is the most smallest part of all matter
Explanation:
2. 
First, we need to find the number of moles of 
at 300K and 1.5 atm using the ideal gas law:
Now use the molar ratios to find the number of moles of ethane to produce this much .
Finally, convert this amount to grams using its molar mass:
3. 
Convert 75 g Zn into moles:
Then use the molar ratios to find the amount of H2 produced.
Now use the ideal gas law 
to find the volume of H2 produced at 23°C and 4 atm:
The best and most correct answer among the choices provided by your question is the first choice.
<span>Although fusion is an energetically favorable reaction for light nuclei, it does not occur under standard conditions on Earth because: fission reactions are always favored over fusion reactions.</span>
