Answer:

The first equation shows the alpha decay.

₉₅Am²²⁴   →    ₉₃Np²³⁷ + ₂He⁴

Explanation:

The americium with atomic wight  224 undergo alpha decay and produce

₉₃Np²³⁷ . The alpha particle emitted is also called helium nuclei. During this decay some gamma radiations also produce as a byproduct.

₉₅Am²²⁴   →    ₉₃Np²³⁷ + ₂He⁴

Properties of alpha radiation:

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic number 2 less than the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

1. Make an observation : My toaster doesn't toast my bread

2. Ask a question : Why doesn't my toaster work?

3. Form a hypothesis : My coffeemaker works when plugged into the outlet

4. Make a prediction : If something is wrong with the outlet, then my coffeemaker also won't work when  plugged into it

5. Conduct an experiment : I plug my coffeemaker into the outlet

6. Analyze the results : There is something wrong with the electrical outlet

Explanation:

The solution to the problem is as shown above.

  • A scientific method follow a methodical way of critically carrying out an inquiry into an observation.
  • Firstly, an observation is usually made with our senses. Here the researcher observes that the toaster does not toast his bread probably after a long wait.
  • He then proceeds to ask why the toaster does not work.
  • To investigate this, the forms a hypothesis. A hypothesis is a scientific guess. It is a tentative proposition about an investigation.
  • The researcher then makes a prediction about the outlet that might be faulty.
  • With this background, he goes on to carry out an experiment to substantiate his findings. This is seen when he plugs the coffeemaker into the outlet.
  • From the analysis of result, he sees that that something is wrong with the outlet.

Moles of gas = 0.369

<h3>Further explanation</h3>

Given

P = 2 atm

V = 5.3 L

T = 350 L

Required

moles of gas

Solution

Ideal gas Law

\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{2\times 5.3}{0.082\times 350}\\\\n=0.369

Avogadro's law : at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

moles of O₂ = 45% x 0.369 = 0.166

moles of Ar = 12% x 0.369 = 0.044

moles of N = 43% x 0.369 = 0.159

Answer:

1.126 M

Explanation:

From the question given, we obtained the following:

Mass of LiBr = 98g

Volume = 1 L

Molarity of LiBr =?

Next, we'll determine the number of mole of LiBr. This is illustrated below:

Molar Mass of LiBr = 7 + 80 = 87g/mol

Mass of LiBr = 98g

Number of mole = Mass/Molar Mass

Number of mole of LiBr = 98/87

Number of mole of LiBr = 1.126 mole

Now, we can calculate the molarity of LiBr. This is illustrated below:

Molarity is defined as mole per unit litre of the solution. Mathematically, it is represented as:

Molarity = mole /Volume

Mole of LiBr = 1.126 mole

Volume = 1 L

Molarity of LiBr =?

Molarity of LiBr = 1.126 mole /1 L

Molarity of LiBr = 1.126 M
