Chemistry
1 answer:
kirza4 [7]3 years ago
4 0

Answer:

λ = 0.5×10⁻⁵ m

E = 39.78×10⁻²¹ J

The given radiation is gamma ray.

Explanation:

Given data:

Frequency of radiation = 6.0 ×10¹³ Hz

Wavelength of radiation = ?

Type of radiation = ?

Energy of radiation = ?

Solution:

Formula:

speed of light = wavelength × frequency

3 ×10⁸ m/s = λ × 6.0 ×10¹³ Hz

Hz = s⁻¹

λ = 3 ×10⁸ m/s /  6.0 ×10¹³  s⁻¹

λ = 0.5×10⁻⁵ m

Energy of radiation:

E = hf

h = planck's constant

f = frequency

E = 6.63×10⁻³⁴ j.s × 6.0 ×10¹³  s⁻¹

E = 39.78×10⁻²¹ J

The given radiation is gamma ray.

What mass of CO2 can be produced from the decomposition of 4.8 moles of Fe2(CO3)3?
gavmur [86]

Answer: 633.6 g of CO_2 can be produced from the decomposition of 4.8 moles of Fe_2(CO_3)_3

Explanation:

The balanced chemical equation for decomposition of Fe_2(CO_3)_2 is :

Fe_2(CO_3)_2\rightarrow Fe_2O_3+3CO_2

According to stoichiometry :

1 mole of Fe_2(CO_3)_2 produce = 3 moles of CO_2

Thus 4.8 moles of Fe_2(CO_3)_2 will rproduce=\frac{3}{1}\times 4.8=14.4moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=14.4moles\times 44g/mol=633.6g

Thus 633.6 g of CO_2 can be produced from the decomposition of 4.8 moles of Fe_2(CO_3)_3

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in which order?
saveliy_v [14]

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.

A hydrocarbon would be an organic molecule in organic chemistry that is made completely of hydrogen as well as carbon. A good example of group 14 hydrides includes hydrocarbons. In general, hydrocarbons lack color and are hydrophobic. Typically, their faint smells are compared to that of gasoline and lighter fluid.

  • The longest unbroken carbon chain should be found and named.
  • Name the groups that make up this chain but instead identify them.
  • Beginning at the end of the chain closest to a substituent group, fraction the chain sequentially.
  • Give each substituent group a corresponding number but also name to indicate its placement.

Therefore, according to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.

Imagine a moving boat making waves in the middle of a pool of water. Also, imagine two observers, one behind the boat and one in
Simora [160]
The person who is behind the boat will see much powerful and bigger waves than the person who is in front of the boat. This phenomenon is caused by the Doppler effect which describes the changes in the observed frequency of a wave whenever there is relative motion between the wave source and the observer.
