Why do you think there are many wind systems between a pole and the equator instead of just one large single wind system

1 answer:

4 0

As a result, the Poles have high pressure (cold air) while the Equator has low pressure (warm air). Hot air from the Equator rises and goes toward the Poles, while colder air from the Poles lowers and moves toward the Equator, resulting in a continuous wind pattern.

son4ous [18]

The molar mass of $Cr(OH)_2$ is 86.02 g/mole .

<h3><u> Explanation:</u> </h3>

The molar mass of a chemical compound is represented as the mass of a unit of that compound separated by the number of substances in that unit, measured in moles. The molar mass is a volume, not molecular, the property of a substance.

The molar mass is a percentage of various examples of the compound, which usually change in mass due to the appearance of isotopes.

From the below attached table, the Molar mass of $Cr(OH)_2$ is 86.0108 g/mol.

Use bond energies to calculate the enthalpy of reaction for the combustion of ethane. Average bond energies in kJ/mol C-C 347, C

ivanzaharov [21]

The enthalpy of reaction for the combustion of ethane 2CH₃CH₃ + 7O₂ → 4CO₂ + 6H₂O calculated from the average bond energies of the compounds is -2860 kJ/mol.

The reaction is:

2CH₃CH₃ + 7O₂ → 4CO₂ + 6H₂O (1)

The enthalpy of reaction (1) is given by:

$\Delta H = \Delta H_{r} - \Delta H_{p}$ (2)
