Answer:
Correct option: a (tetrahedral)
Explanation:
According to VSEPR theory tetrahedral arrangement comes when central atom have four electrons pair in the valence shell and only in this arrangement electron pair will fell less repulsion that is why it is arranged in this way and VSEPR theory electrons pair are arranged in such a manner that they fell less repulsion.
they might have different number of bond pair and lone pair that depens on the number of bonded to other atom.
Hence opion a is correct.
Answer:
Explanation:
The name tells you that this is a binary compound (contains two elements).
It contains a metal and a nonmetal, so it is a binary ionic compound. The general rule is:
Name of compound = name of metal name of ion (two words)
Name of metal = tin(IV), so the tin ion has a charge of 4+
Name of ion = bromide. Br is in Group 17, so bromide ion has charge of 1-.
Answer:
C
Explanation:
The high specific heat capacity of water means that it takes much more energy to raise the temperatures of water by one (1) degree than land. This means that on a hot sunny day, land temperatures would increase dramatically while ocean temperatures would only rise slightly. Conversely, at night, the land cools rapidly while oceans cool slowly hence the temperatures drop slightly.
Wouldn’t it be “B”? Can’t soemthing still get corroded under paint?
