Answer:
<h2>
0.50 m/s</h2><h2>
</h2>
Explanation:
Velocity = distance over time
where distance = 5.20 m
time = 10.4 s.
velocity = <u> 5.20 m </u>
10.4 s.
= 0.50 m/s
Answer:
Ethylene diamine will bond to the Central metal via a lone pairs of electrons on nitrogen
Explanation:
Complexes are formed by coordinate bond formation. Before a coordinate bond is formed, one of the species must have a lone lair of electrons available for donation into empty orbitals on the central metal.
Ethylene diammine contains nitrogen which has a lone pair of electrons. The two lone pairs on the two nitrogen atoms can bond with the central metal. This makes ethylene diammine a bidentate ligand (two bonding atoms).
The statement that best explains why heating a liquid affects its viscosity is that "The molecules move faster at higher temperatures and overcome attractions more easily."<span>. Remember that viscosity is a physical property of the fluids that measure the resistance (opposition) to flow and it, generally decreases, as the temperature increases and the intermolecular force decrease.</span>
Answer:
C. 2-methylpropane
Explanation:
There are rules guiding the naming of hydrocarbons. Some of the rules are:
1.) The longest continuous chain is the parent chain:
The longest chain here is made up of 3-carbon atoms which is a propane compound
2.)The carbon atoms are numbered in the parent chain to indicate where branching or substitution takes place.
Here, it is in the second carbon atom in propane.
The branched group is methyl- which is a methane molecule that has lost a hydrogen atom.
This makes ths name of the compound to be:
2-methylpropane
The freezing point depression can be explained in terms of vapor pressure adding solvent will decrease molecules
