Read the passage below about different types of radiation. Different types of radiation have different penetrating abilities. Fo

r example, gamma rays can pass through cloth and paper, but alpha particles are blocked by cloth and paper. Beta particles are blocked by aluminum foil, but gamma rays are not. However, all three types of radiation are blocked by thick concrete or lead. Now, examine a table of penetrating powers of different types of radiation. Material 1 2 3 Lead Stopped Stopped Stopped Cloth Not stopped Stopped Stopped Aluminum foil Not stopped Stopped Stopped Wood Not stopped Stopped Stopped Paper Not stopped Stopped Not stopped Thick concrete Stopped Stopped Stopped Based on the information, at which numbered spot in the table does each type of radiation belong?

<h2>Answer : 1 is gamma, 2 is alpha and 3 is beta radiations.</h2><h3>Explanation :</h3>

In the given information all the radiations were stopped by the lead block, if we assume that first radiations were gamma radiation, as they were not stopped by the cloth whereas all other radiations were stopped.

In second case, aluminum foil and wood were able to block alpha and beta radiations. Whereas, paper was used to stop the alpha particles but not the gamma and beta rays. And then a thick concrete stopped all the radiations.

This clarifies that the first radiation are gamma rays, second is alpha rays and third is beta rays.

The decomposition of N2O to N2 and O2 is a first-order reaction. At 730°C, the rate constant of the reaction is 1.94 × 10-4 min-
fomenos

Answer:

The total pressure after one half is 6.375 atm.

Explanation:

The initial pressure of product is increases while the pressure of reactant would decrease.

Balanced chemical equation:

2N₂O  → 2N₂ + O₂

The pressure of N₂O is 5.10 atm. The change in pressure would be,

N₂O = -2x

N₂ = +2x

O₂ = +x

The total pressure will be

P(total) = P(N₂O) + P(N₂)  + P(O₂)

P(total) = ( 5.10 - 2x) + (2x)  + (x)

P(total) = 5.10 + x

After one half life:

P(N₂O)  = 1/2(5.10) = 5.10 - 2x

x = 5.10 - 1/2(5.10) /2

x = 5.10 - 0.5 (5.10) /2

x = 5.10 - 2.55 / 2

x = 2.55 /2 = 1.275 atm

Thus the total pressure will be,

P(total) = 5.10 + x

P(total) = 5.10 + 1.275

P(total) = 6.375 atm

Do you agree or disagree with the following statement:
Anarel [89]

Answer:

Agree

Explanation:

Theories are refined and then become laws and laws are somehow more important than theories. In science actually what a law is, is a descriptive generalization. So we talk about the laws of thermodynamics that tell you about heat under different circumstances.

If a chemist has 17.8 moles of N2H4O3, what is the mass of the sample?<br><br> show work plz
harkovskaia [24]

(\frac{17.8mole}{1} )( \frac{66grams}{1mole} ) \:  \:  \:  \:  17.8 \times 66 = 1.17 \times  {10}^{3} grams
the way that you get 66 is by adding he atomic mass unit of each atom in the formula. so N2 is 14 + 14 H4 is 1 * 4 and 03 is 16 * 3
