Answer: Nuclear decay rates are constant

Explanation: Nuclear or radioactive decay occurs when energy is lost in unstable atoms, with emitting radiation. In this case, there are radioactive alpha, beta, gamma and other particles. In fact, this process presupposes the spontaneous transformation of unstable atomic nuclei. The characteristic of such processes is half-life, which represents a time period necessary for half of the amount of radioactive material to decay. It is not always predictable when a particular radioactive particle from an unstable atomic nucleus will be emitted, but the decay rate over time is constant.

The answers are as follows,

1. 4.71 L,

2. 3.29 L,

3. 1634.6 torr

Explanation:

All the above problems can be sorted out using the Boyle's law represents the relationship between the volume and pressure.

It can be expressed as follows,

P1V1 = P2V2

Rearranging the above expression, we get,

$$ V2 = \frac{P1V1}{V2}$

1) The first case can be solved as,

$$V 2=\frac{921 \mathrm{mm} \mathrm{Hg} \times 3.89 \mathrm{L}}{760 \mathrm{mm} \mathrm{Hg}}=4.71 \mathrm{L}$

2) The second case can be solved as,

$$V 2=\frac{25 L \times 600 \text { torr}}{4560 \text { torr}}=3.29 L$

3) The third case can be solved as,

$$P 2=\frac{7.43 L \times 1100 \text { torr}}{5 L}=1634.6 \text { torr}$

Thus the answers for all the three cases are found as,

1. 4.71 L,

2. 3.29 L,

3. 1634.6 torr respectively

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

- zinc [Zn] + copper sulfate [Cu(SO4)
Balanced equation:Zn + Cu(SO4) → Zn(SO4) + Cu

- aluminum [Al] + copper sulfate[Cu(SO4)]Balanced equation:2Al + 3Cu(SO4) → Al2(SO4)3+ 3Cu

- zinc [Zn] + silver nitrate [Ag(NO3)]Balanced equation:Zn + 2Ag(NO3) → 2Ag + Zn(NO3)2

- copper [Cu] + silver nitrate [Ag(NO3)]
Balanced equation:Cu + Ag(NO3) → Cu(NO3) + Ag

Examples of a pure substances

DiKsa [7]

Answer:

Explanation:

Examples of pure substances include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate). Crystals, in general, are pure substances. Tin, sulfur, and diamond are examples of pure substances that are chemical elements.
