Its rate constant again for nuclide is 0.388 days per one. First-order kinetics governs how nuclear decay happens. At 45.0 g down 12.1 g, a nuclide degrades every 3.40 days.

<h3>How do you define a nuclide?</h3>

Nuclide, also known as nuclear species, is an atom species that is identified by the amount of protons, neutrons, and the energetic state of the nucleus. As a result, a nuclide is identified by its quantity (A) and atomic number (Z).

<h3>What is an example of a nuclide?</h3>

A similar options is a type of atom that has a certain ratio of protons to neutrons in its nucleus, such as carbon-13's 6 protons to 7 neutrons.

Butyl butyrate is an ester that is a naturally occurring oil used in the flavor industry for its fruity scent. If the steam dist
Snezhnost [94]

Answer:

The correct answer is 62.5 %.

Explanation:

Based on the given information, the partial pressure of butyl butyrate is 50 mmHg and the partial pressure of water is 710 mmHg.  

Hence, the total pressure is 710+50 = 760 mmHg

According to Dalton's law of partial pressure,  

Partial pressure = mole fraction * total pressure

Mole fraction of water is,  

Partial pressure of water/Total pressure = 710/760 = 0.93

Similarly, the mole fraction of butyl butyrate is,  

Partial pressure of butyl-butyrate/Total pressure = 50/760 = 0.07

Therefore, mole% of water is 0.93 * 100 = 93 %

For calculating mass%,  

Mass of H2O = 0.93 * 18 = 16.8 grams (The molecular mass of water is 18 grams per mole)

The molecular mass of butyl-butyrate is 144 gram per mole

The mass of butyl-butyrate = 144 * 0.07 = 10.08 grams

The mass percent of water will be,  

Mass % of water/Total mass % * 100 = 16.8 / 10.08 + 16.8 * 100 = 62.5%.

Justify the statement, "nuclear energy is harmful as well as useful."​
Olenka [21]

Nuclear energy is harmful because it releases of harmful ionizing radiation and has been employed in the production of atomic bombs and hydrogen bombs.

Nuclear energy is beneficial in that it produces vast amount of energy for domestic and industrial purposes.

<h3>What is nuclear energy?</h3>

Nuclear energy refers to the energy which is produced as a result of the changes that occur in the nucleus of atoms of elements.

Nuclear energy produces the largest amount of energy when compared to other forms of energy sources.

Nuclear energy is produced by two types of nuclear reactions:

  • Nuclear fission and Nuclear fusion

Nuclear energy is harmful in that it results in the release of harmful ionizing radiation which damages cells and tissues of living organisms.

Nuclear energy is also harmful because nuclear energy has been employed in the production of atomic bombs and hydrogen bombs.

On the other hand, nuclear energy is beneficial in that it produces vast amount of energy which can be used for domestic and industrial purposes. It also produces fewer wastes that damage the environment compared to fossil fuels.

In conclusion, nuclear energy is both beneficial and harmful.

A 24% acid solution is mixed with a 14% acid solution to form a 19% acid solution. How many liters of the 24% acid solution are
Kay [80]

Answer: 5 Liters

Explanation:

According to the dilution law,

M_1V_1+M_2V_2=M_3V_3

where,

M_1 = concentration of first solution = 24%

V_1 = volume of first solution = x L

M_2 = concentration of second solution = 14%

V_2 = volume of second solution = (10-x) L

M_3 = concentration of final solution = 19%

V_2 = volume of final solution = 10 L

Putting i the values, we get:

24\times x+14\times (10-x)=19\times 10

x=5L

Therefore, 5 Liters of the 24% acid solution are used to make 10 liters of the 19% acid solution.
