Answer:
a. NO2
b. NH3
c. CO2
Explanation:
a. For the pair of compounds CO2 or NO2 the one with the highest boiling point is __________ .
The answer is NO2. It has a higher boiling point than CO2 because it exhibits dipole-dipole interactions.
b. For the pair of compounds NH3 or CH4 the one with the highest boiling point is _________
NH3 has a higher boiling point compared to CH4. This is due to the presence of the hydrogen bonds in NH3,
c. For the pair of compounds CS2 or CO2 the one with the highest boiling point is _________
CS2 has a higher boiling point than CO2. This is because of the high molecular mass of CS2.
To be able to compare the result with other experiments it has to be reported in moles.
number of moles = mass / molecular weight
number of moles of Mg(H₂PO₄)₂ = 600 / 218 = 2.75 moles
B. Mg and CI. This is the one.
A shape of a 'p' orbital looks like a balloon pinched in the middle.
Answer:
Densities
Explanation:
A planet is a body which orbits the Sun (or father's it's sun) directly and is massive enough to show a hydrostatic equilibrium ( a spheroid) and be resilient in dominating its orbit
What comes to mind as we mention the word planet is specifically, the eight major bodies of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Note that Pluto once was considered a planet from the 17th century until 2006 and has now been reclassified as a dwarf planet.
Density is the measure with ratio of one quantity to another quantity.
It can quantitatively be a measure of the mass of matter contained by a unit volume.
The knowledge of density of gases comes in handy to calculate the relative amount of substances.
