Answer:
Here's what I get
Explanation:
1. Water
The O-H bond in water is highly polar.
It has about one-third ionic character.
The partially-positive H atoms and partially negative O atoms strongly attract each other by hydrogen bonds.
It takes a large amount of energy to separate the water molecules from each other.
Thus, the boiling point of water is relatively high (100 °C).
2. Acetone
The C=O bond in acetone is much less polar.
It is less than 20 % ionic.
The dipole-dipole attractions in acetone are much weaker than the hydrogen bonds in water.
It takes much less energy to separate the acetone molecules from each other.
Thus, even though the molar mass of acetone is more than three times that of water, the boiling point of acetone is only 56 °C.
Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue
reacts with water to produce pink colored
complex.
In this complex,
ion forms an octahedral complex with six
ligands.
As
is a weak field ligand therefore
ion remains in low spin state.
Hence electronic configuration of
ion in this octahedral geometry is
with total three unpaired electrons.
Answer:
it can cause blood cancer (leukemia)
Answer:
48.075g(or 48g in correct sig figs)***
Explanation:
=48.075g
*64.1g is the mass of SO2 which is calculated by simply taking the mass of sulfur and oxygen(but doubling it since there are two oxygens) and adding them together(32.1+2x16.0)
**btw the mol units cancel because of dimensional analysis in case anyone was wondering why
***if your teacher is like mine and specifically wants your answer in correct sig figs, use the answer in parentheses as the original problem only has 2 sig figs
Atoms are made up of Protons and neutrons in the nucleus, and then rings of electrons on the outer shells! so in short, protons, neutrons and electrons. :)
