Answer: The order of increasing energy is: radio < infrared < red < blue < UV < x rays

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them.  

The electromagnetic radiations consist of gamma rays , X rays , Ultraviolet , Visible , Infra red , microwaves and radio waves arranged in order of decreasing frequency and increasing wavelengths. The visible region consists of violet , indigo , blue , green , yellow, orange and red lights in order of decreasing frequency or increasing wavelength

The relationship between energy  and frequency of the wave follows the equation:

E=h\times \nu

where,

\nu = frequency of the wave

E = energy of wave

From the above relation, it is visible that energy and frequency follow direct relation. For increase in value of frequency, energy increases and vice-versa.

Thus the order of increasing energy is: radio < infrared < red < blue < UV < x rays

Why is there a discrepancy between a heat of reaction ob-tained from calorimetry and one obtained from bond energies?
Eva8 [605]

While bond energies and bond enthalpies can be used to estimate the heat of reaction (enthalpy change of a reaction), H, the heat of neutralization is the heat released when 1 mole of water is generated by the reaction of an acid and a base (reaction).

For the same type of bond, bond enthalpies differ from compound to compound. For instance, the C-H bond enthalpy in methane is nearly identical to that of ethane, butane, etc. When we look up the bond enthalpy for a C-H bond in a table of bond enthalpies, the average number that results may only be accurate to two or three significant figures.

Each compound's enthalpies of production are listed, and those numbers take into account any minor variations in the enthalpies of each bond. Therefore, the result will be more accurate if you utilize formation enthalpies rather than average bond enthalpies to compute a given reaction's enthalpy change.

Explanation:

In a physical change, the mass remains constant.

Hence the mass of the ice is the same as the water, which is 20g.

A reaction produces .815 moles of H2O. How many molecules produces?
Vera_Pavlovna [14]
To find out the number of water molecules produced simply use Avogadro’s constant, where 1 mol of any compound is equal to 6.02 x 10^23 molecules of the substance.

Multiply 0.815 to this value.
