Please find the attached photo : ( IT is explain the geometry of CH3OH)
1- The molecular geometry of CH3OH ( as you see at the picture attached ) is tetrahedral at the C atom.
2- The molecular geometry of CH3OH (as you see at the picture attached ) is bent at the O atom.
3- There are three H atoms surround the C atom.
4- There are 2 atoms (C , H) surround the O atom.
5- There are 2 lone pairs on the O atom
Answer:
The density of the liquid is 4.9 g/ml
Explanation:
Density of a liquid is usually measured by filling a beaker of known weight and known capacity (total volume in ml you can fill it) and weighing it. The difference between the total weight (beaker+liquid) and the beaker weight is the liquid weight. Finally, you must divide <em>liquid weight/volume</em> to obtain density.
For the problem:
beaker=15 g
beaker+liquid=64 g
⇒liquid= 64 g - 15 g = 49 g
density= =
= 4.9 g/ml
Answer: The correct option is D.
Explanation: Table salt has a chemical formula NaCl.
This compound is an ionic compound.
Ionic compound is defined as the compound formed when there is a complete transfer of electron from one element to another.
NaCl consists of two elements, Sodium (Na) and Chlorine (Cl)
Sodium has an atomic number of 11 and its electronic configuration is . This element has 1 extra electron, so in order to have stable electronic configuration, this element will release 1 electron and forms a cation.
Chlorine has an atomic number of 17 and its electronic configuration is . Chlorine element requires 1 electron to have stable electronic configuration. Hence, this element will accept 1 electron and will form an anion.
When these two element combine together, Sodium will give away 1 electron to chlorine and therefore, chlorine becomes anion.
Hence, the correct option is C.
