Which ion(s) would bond by electrostatic attraction with an ion of Fluorine?
satela [25.4K]

Answer:

Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.

Calculate the root mean square (rms) average speed of the atoms in a sample of xenon gas at 0.15 atm and -55c
GrogVix [38]
Answer:
Vrms is 149.7266 m/sec

Explanation:
The root means square velocity of a gas can be calculated as follows:
Vrms = \sqrt{ \frac{3RT}{M}}
where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg

Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec

Hope this helps :)

On a recent excursion chemistry student extraordinaire, Melvin Blackthorne, found a gold colored coin at a flea market. The vend
ankoles [38]

Explanation:

What is the density of the coin?

Formular for density = Mass / Volume

Mass of coin = 18.82g

Volume occupied = 7.3ml - 5.2ml = 2.1ml

Density = 18.82 / 2.1 = 8.9619g/ml

what is the mass of the iceberg in metric tons (1 metric ton = 1000 kg)?

Density = 0.9I68g/cm^3

Volume = 35,000 m^3 = 3.5e+10cm^3 (Conversion to cm^3)

Mass = Volume * Density = 3.5 * 10^10 * 0.9I68 = 3.2088 * 10^10g

Upon conversion to kg by dividing by 1000

Mass = 3.2088 * 10^7kg

(1 metric ton = 1000 kg)

Mass = 3.2088 * 10^3 metric tonnes

In your own words explain how Archimedes' principle can be used to measure the volume of an irregularly shaped solid.

By definition, all matter has mass and occupy space. Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. And the weight of fluid displaced is the volume of fluid.

So the volume is obtaiined by placing the irregularly shaoed solid and noting the volume of fluif displaced.

what volume of water (d = 1.000g/mL) is about to impact Melinda's head?

Volume of sphere = V = (1 / 6) πd³

Inserting the value of V = 10.7 cm

Volume = 641.43cm³
