Hello!
BeH₂ is a linear molecule, while CaH₂ is an angular molecule.
The difference between these two molecules is given by the number of electrons they have. Be is in the 2nd period of the Periodic table, and the ion Be⁺² doesn't have any free electron pairs when bonding to H. Ca is in the 4 period of the periodic table, meaning that it has more electrons, and the ion Ca⁺² has two free electron pairs when bonding to H that makes the molecule angular by pushing the bonds at an angle by sterical hindrance.
Have a nice day!
air pollution would cause trees to die and animals to die . It would coaus most harm by killing everything on land and in the sea beacuse the animals that die might wash away in the ocean killing other animals slowly but surely. and it doesnt help there is soil erosion sooner rather that later it will turn into nothing.
Explanation:
Answer:
Final volume = 0.103M x446ml/0.184m = 250ml
Explanation:
As time passes, the volume of solutions in the second beaker decreases and that in the first beaker increases. If we wait long enough, the final volumes and concentration in the beakers would be,
First beaker
Final concentration = 0.184M
Final volume = 0.296M x 284ml/0.184 = 457ml
Second beaker
Final concentration = 0.184M
Final volume = 0.103M x446ml/0.184m = 250ml
