Yes it will sink because it has a greater density than the water hope this helps.
By the way can I be brainliest :)
I think they test ideas about chemical evolution by doing experiments. Hope this helps
Answer:
Four
Explanation:
P has five valence electrons. It can form bonds to three other atoms (like H) to form a triangular pyramidal molecule with a lone pair on the P atom.
If P atoms are to form bonds with each other, we can get a stable arrangement by putting each atom at the corner of a tetrahedron.
In a P₄ molecule, each atom still has three bonds and a lone pair.
Your answer is
Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O I hope it is at least :P
