Radioactive decay is a spontaneous process in which unstable nuclei emit radioactive particles and energy. Fission occurs as the result of high-energy bombardment of nuclei that cause them to break into smaller nuclei, radioactive particles, and energy. All fission events are not the same. The nuclei split in a number of ways to produce several different products.

<h3>What is Radioactive?</h3>

The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent kinds of decay, and they all entail the emission of one or more particles.

Beta decay is a result of the weak force, while the nuclear force and electromagnetism are in charge of the other two mechanisms. The capture of an inner electron from one of the electron shells by an unstable nucleus is the fourth prevalent form of decay. A series of electrons drop as a result of that electron being lost from the shell.

How many moles are in 17.2g k2s
Natalija [7]

Answer: 0.156 mol

Explanation:

To find the moles of 17.2 g K₂S, we need to know the molar mass to convert.

17.2g*\frac{mol}{110.256 g} =0.156 mol

What is the sign of enthalpy change for (a), an endothermic reaction? (b). an exothermic reaction?
fenix001 [56]

Answer:

The answer is: (a) positive; (b) negative.

Explanation:

The change in enthalpy (ΔH) of a reaction is the amount of energy absorbed or released during a chemical reaction carried out at constant pressure.

a) In an endothermic chemical reaction, heat energy is absorbed by the system from the surrounding. Therefore, the sign of enthalpy change for an endothermic process is positive, ΔH= positive.

b) In an exothermic chemical reaction, heat energy is released by the system into the surrounding. Therefore, the sign of enthalpy change for an exothermic process is negative, ΔH= negative.

Calculate the following:
Brrunno [24]

Follow these steps to solve the given equation:

Multiply the two decimal figures together and find the sum of the exponents, that is,

(1.5 * 1.89) * 10 ^4+3

(2.835) * 10^7

10^7 can also be written as e.70

'e' stands for exponential. 

Therefore, we have  2. 835 e 7.0 = 2.8 e 7.0.

Based on the calculations above, the correct option is A.
