Which substance most likely has the strongest intermolecular forces?
serious [3.7K]

Answer: -

Acetic acid

Explanation: -

The intermolecular force of attraction depends on the strength or extent of Hydrogen bonding present in a substance.

Benzene and chloroform does not have hydrogen bonding being non polar molecule.

Water has hydrogen bonding being polar.

However acetic acid being most polar has the maximum hydrogen bonding.

Thus acetic acid has the strongest intermolecular forces of attraction.

The acceleration of a sprinter is 10 m/s2. The force exerted on the starting blocks is 650 N. What is the mass of the sprinter?
jek_recluse [69]

The relation between force, mass of an object and its acceleration is given by following equation

F = mass of object X acceleration

The unit of Force is Newton (N)

unit of acceleration is ms⁻²

unit of mass if Kg

[all these are SI units]

Mass of object =\frac{Force}{acceleration}

mass of sprinter =\frac{650}{10}=65kg

You have 7.86 x 10^23 molecules of NaCl. This would be equal to ___ grams of NaCl.
sergij07 [2.7K]

7.86 \times 10 {}^{23} atoms \\  \frac{7.86}{6.022}  \times  \frac{10 {}^{23} }{ {10}^{23} }   = 1.305\: moles

1.305 × (23+35.5) = 76.34 grams

summarize rutherford's model of an atom, and explain how he developed thus model based on the results of his famous gold-foil ex
Ainat [17]
Rutherford's atomic structure model was revolutionary. Contrary to J.J. Thompson's "plum pudding" model (which consisted of a solid, even mixture of protons and electrons), Rutherford's model consisted of one small, positively charged, dense nucleus, a layer of empty space, and a layer of negatively charged electrons. He came to this conclusion through his gold-foil experiment. He shot a ray of alpha particles towards the thin gold foil, and to Rutherford's surprise, some of the rays reflected back instead of going straight through the foil as he originally thought.

1. Energy in foods is provided by
ELEN [110]

Answer:

Energy in foods is provided by macro-nutrients.

Explanation:

Nutrients are “environmental substances” used for growth, energy, and bodily functions of the  organisms. Those nutrients that are required  in larger amounts are called macro-nutrients.

There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in  form of “calories”. For example:

  • In carbohydrates, there are '4 calories' of energy per gram.
  • In proteins, there are '4 calories' of energy per gram.
  • And in lipids, there are '9 calories' of energy in one gram.

This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.
