A large unstable nucleus becomes tinier and emits an alpha particle during Alpha decay. 4/2He or the alpha particle that consists of two protons and two neutrons can be discharged from the nucleus during the disintegration of radioactive decay. It has a charge of positive 2.

Answer: The product of the radioactive decay $_2^4\textrm{He}$ is called as alpha particle.

Explanation:

Radioactive decay of the nuclei happens when a nuclei has to attain some sort of stability. It undergoes various decay processes and releases various particles during these decay process. The types of particles released are:

Alpha particle: These are released during alpha decay. The particle released carry a mass of +4 units and a charge of +2 units. It is represented as $_2^4\alpha$
Beta particle: These are released during beta decay. The particle released carry a mass of 0 units and a charge of -1 units. It is represented as $_{-1}^0\beta$
Gamma particle: These are released during gamma decay. The particle released does not carry any charge and is electrically neutral. It is represented by $\gamma -\text{particle}$

Hence, the correct answer is alpha particle.

How to change 5 % W/V of NaCl to ppm , M ? molar mass = 58.5 please clear explain

11Alexandr11 [23.1K]

Answer:

50000ppm and 0.855M.

Explanation:

ppm is an unit of chemistry defined as the ratio between mg of solute (NaCl) and Liters of solution. Molarity, M, is the ratio between moles of NaCl and liters

A 5% (w/v) NaCl contains 5g of NaCl in 100mL of solution.

To solve the ppm of this solution we need to find the mg of NaCl and the L of solution:

mg NaCl:

5g * (1000mg / 1g) = 5000mg

L Solution:

100mL * (1L / 1000mL) = 0.100L

ppm:

5000mg / 0.100L = 50000ppm

To find molarity we need to obtain the moles of NaCl in 5g using its molar mass:

5g * (1mol / 58.5g) = 0.0855moles NaCl

Molarity:

0.0855mol NaCl / 0.100L = 0.855M

You observe 2 waves named alpha and beta. The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz. Base

MAVERICK [17]

Answer:

shorter wavelength = alpha wave

Explanation:

Given that,

The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz.

We need to compare the wavelengths of these two waves.

For alpha wave,

$\lambda_1=\dfrac{c}{f_1}\\\\\lambda_1=\dfrac{3\times 10^8}{5}\\\\=6\times 10^7\ m$

For beta wave,

$\lambda_2=\dfrac{c}{f_2}\\\\\lambda_2=\dfrac{3\times 10^8}{2}\\\\=15\times 10^7\ m$

From the above calculations, we find that the wavelength of the alpha wave is shorter than the wavelength of the beta wave.

A reaction in the laboratory yields 5.98 g KAI(SO2)2, How many moles of potassium aluminum

Ivahew [28]

Answer:

0.0308 mol

Explanation:

In order to convert from grams of any given substance to moles, we need to use its molar mass:

Molar mass of KAI(SO₂)₂ = MM of K + MM of Al + (MM of S + 2*MM of O)*2

Molar mass of KAI(SO₂)₂ = 194 g/mol

Now we calculate the number of moles of KAI(SO₂)₂ contained in 5.98 g:

5.98 g ÷ 194 g/mol = 0.0308 mol
