Hey can someone help me and show work please

Ivahew [28]

Answer: 2.54g

Explanation:

Molar Mass of H2O2 = (2x1) + (2x16) = 34g/mol

1mole (34g) of H2O2 contains 6.02x10^23 molecules

Therefore Xg of H2O2 will contain 4.5x10^22 molecules i.e

Xg of H2O2 = (34x4.5x10^22)/6.02x10^23 = 2.54g

Typical frequencies for several types of electromagnetic radiation are given below. Calculate the energy of each type of radiati

marusya05 [52]

Explanation:

The energy of electromagnetic radiation is given by :

$E=h\nu$

Where, h is the Planck's constant

(a) A gamma ray, $\nu = 1.64\times 10^{20}\ Hz$

Energy,

$E=6.63\times 10^{-34}\times 1.64\times 10^{20}\\E=1.08\times 10^{-13}\ J$

(b) A microwave, $\nu = 4.95\times 10^{10}\ Hz$

Energy,

$E=6.63\times 10^{-34}\times 4.95\times 10^{10}\\E=3.28\times 10^{-23}\ J$

Energy,

$E=6.63\times 10^{-34}\times 2\times 10^{6}\\E=1.32\times 10^{-27}\ J$

Therefore, this is the required solution.

An atom in an excited state contains more of what type of energy than the same atom in the ground state? An atom in an excited s

kupik [55]

Answer: An atom in an excited state contains more of kinetic energy than the same atom in the ground state.

Explanation:

Kinetic energy is the energy acquired by an object due to its motion. And, thermal energy is the internal energy of an object arisen because of the kinetic energy present within the molecules of the object.

Potential energy is the energy acquired by an object due to its position.

The total energy present at the center of mass of an object is known as mass-energy.

So, when an atom gets excited then it means it is gaining kinetic energy due to which it moves from its initial position after getting excited.

Thus, we can conclude that an atom in an excited state contains more of kinetic energy than the same atom in the ground state.

1) A mixture of anhydrous sodium carbonate and sodium hydrogencarbonate of mass 10.000 g was heated until it reached a constant

vodomira [7]

The masses of the components are obtained as;

Sodium hydrogen carbonate = 3.51 g
Sodium carbonate = 8.708 g

<h3>What is decomposition?</h3>

The term decomposition has to do with the breakdown of the given substance into its components. The components of sodium hydrogen carbonate could be identified as water vapor, carbon dioxide gas and sodium carbonate. Among these products that have been listed here, we can see that it is only the sodium carbonate that remains as a solid. The others are gases that move away from the system that is under study.

Now putting down the equation of the reaction, we have;

$2NaHCO_{3} (s) ----- > Na_{2} CO_{3} (s) + CO_{2} (g) + H_{2} O(g)$

Now, the loss in mass must be due to the carbon dioxide and the water. Hence we obtain the loss in mass to be 10.000 g - 8.708 g = 1.292 g

Mass of sodium hydrogen carbonate = 2 * 88 g/mol * 1.292 g/62 g/mol

= 3.51 g
