What is the strongest interparticle force in a sample of kr?
Anit [1.1K]
Answer:
            London Dispersion Force<span> is the strongest interparticle force in a sample of Kr.

Explanation:
                   Krypton belongs to Noble Gases. They exists in monoatomic form as they are inert in nature and are very less reactive. So, as there is no polarity in Krypton so it will fail to create either Dipole-Dipole or Hydrogen Bond Interactions between its atoms. While, London Dispersion Forces or Van Der Waals forces can exist between Kr atoms. When Kr atoms approaches one other they create Instantaneous dipole. This</span> Instantaneous dipole induces dipole in second Kr atom and the process starts propagating. Hence, interactions are generated between Kr atoms.

Can someone help me find the theoretical value of methane? It is chemistry
antiseptic1488 [7]

Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F). Methane in general is very stable, but mixtures of methane and air, with the methane content between 5 and 14 percent by volume, are explosive. Explosions of such mixtures have been frequent in coal mines and collieries and have been the cause of many mine disasters.

Iron is found in Earth's crust as several iron compounds. Calculate the mass in kilograms of the amount of each of the following
myrzilka [38]

2074.74 kg is the mass of siderite in which 1x10^3 kg of iron is present.

Explanation:

Mass of iron is given as 1x10^3 Kg

mass of iron in siderite FeCO3 can be known

number of moles in 1x10^3 Kg  iron is calculated by the formula.

number of moles = \frac{mass}{atomic mass of one mole}

atomic weight of iron is 55.84

number of moles = \frac{1000.1000}{55.84}

 n= 17908.309 moles of iron in 1000 kg

1 mole of FeCO3 has 1 mole of Fe

x moles of FeCO3 will have \frac{x}{17908.309} moles

\frac{1}{1} = \frac{x}{17908.309}

x = 17908.309 moles of FeCO3 is there.

so mass can be calculated as number of moles x molar mass of one mole of the substance.    (molar mass of siderite is 115.854 grams/mole)

17908.309 x 115.854

= 2074749.230 grams of siderite

(the molar mass is converted to kg/mole as the mass of iron is given by kg.

0.1158 kg is the molar mass of siderite)

2074749.230 grams of siderite is converted to kilogram

2074.74 kg is the mass of siderite in which 1x10^3 kg of iron is present.
