which types of intermolecular forces are most likely to dominate between large molecules containing long chains of carbon atoms
Serga [27]

Van der waals force

Explanation:

The intermoleclular forces are attraction between molecules. Interatomic forces are attraction between atoms in a compound.

In most hydrocarbons the weak Van der waals attraction are known.

  • These forces are weak attraction joining non-polar and polar molecules together.
  • These forces can also be found in layers of graphite.
  • They are of two types;

London dispersion forces are attraction that exists between non-polar molecules and the noble gas.

Dipole - Dipole attractions are forces of attraction existing in polar molecules.

In hydrocarbons, we have non-polar molecules and intermolecular attraction is london dispersion forces.

How do different bridge designs react to stong winds
anastassius [24]

Which of the following measurements is equal to 150 dL?
MrRissso [65]
This is a case of metric system of measurements. The scale of the metric system only differs by a factor of 10. The scale (from greatest to least) is kiloliter, hectoliter, dekaliter, liter, deciliter, centiliter and milliliter. If the unit is 150 dL, and you want to find the equivalent dkL measurement, just move the decimal point 2 decimals places to the left (just follow the scale). The same procedure is done for the other metric units.

150 dL = 1.5 dkL
150 dL = 15 L
150 dL = 1,500 cL
150 dL = 15,000 mL

From the choices, the answer is letter C.

Is it better for an element to be more abundant or less abundant?
PIT_PIT [208]

I believe it's better for it to be more abundant because it's better to have more then less. Take water as an example. Water is an important factor to our survival and if we didn't have enough of that we would be in trouble.  Or if we needed food but there wasn't enough more people would be dying from starvation. It's better to have a little more than a little less.

WORTH 100 POINTS PLEASE HURRY!!!!!!!!
neonofarm [45]

Answer:

The answer is B

Explanation:

Less air means less air pressure. At a certain point, there is very little air pressure to push against the outward pressure of the helium inside the balloon. It will then expand until the rubber breaks, and the balloon bursts
