D would be your best bet because evaporation occurs when water is heated, it then vibrates and then magic!
Answer:
544.522 Hours
Explanation:
a) Mass = 12.5 kg = 12500 g
Now, Number of moles is given as
No of moles = Mass of Cr / Molar mass of Cr
= 240.38 moles
3 mols of electrons are required
Converting moles of e- to coulombs of charge, (1 mol of electrons = 96500 C )
Q =721.14 mol×96500 C/mol
=69590010 of charge
We know that, Q = I×t
where Q is charge, I is current and t is time required.
=196281.97 seconds
=544.522 Hours
Think about your question you literally just asked. If the person is a non-English speaker than from where they come from it may mean something totally different to them than it does to us. It could also demonstrate a totally different way of saying the word as well.
Answer:
I think it's A.
Explanation:
Metameric bodies are divided into segments called annuli. Annuli are covered in tiny hairs called setae. Setae help the worms move. So yes it's A.

Covalent bonds form when electrons are shared between two nonmetals. A covalent bond involves a pair of electrons being shared between atoms.
Atoms form covalent bonds in order to reach a more stable state.
A given nonmetal atom can form a single, double, or triple bond with another nonmetal. Which type of bond is formed between the atoms depends on their numbers of valence electrons.
