Which missing item would complete this beta decay reaction? PLATO

goldfiish [28.3K]

Answer: $_{-1}^0\beta$

Explanation:

General representation of an element is given as: $_Z^A\textrm{X}$

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Beta decay : In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.

$_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta$

The given reaction would be represented as:

$_{43}^{98}\textrm{Tc}\rightarrow_{44}^{98}\textrm{Pb}+_{-1}^0\beta$

Point E is located at (-2, 2) and point F is located at (4-6). What is the distance between

Flauer [41]

Answer:

Explanation:

Given endpoints:

E (-2,2) and F(4, -6)

To find the distance between two points;

Use the expression below;

D = $\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1})^{2} }$

x₁ = -2,

x₂ = 4

y₁ = 2

y₂ = -6

Insert the parameters and solve;

D = $\sqrt{(-6 - 2 )^{2} + (4 -+ 2)^{2} }$

D = $\sqrt{64+ 36 }$ = 10

What is the Golden Rule of Solubility? A. polar dissolves nonpolar. B. nonpolar dissolves polar. C. like dissolves unlike D. lik

DerKrebs [107]

Answer: D. like dissolves like

Explanation:

The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Hydrocarbons are non polar in nature due to less difference between the electronegativities of carbon and hydrogen and thus are soluble in non polar solvents only.

Ionic compounds which are formed by elements with high electronegativity difference are polar in nature and thus dissolve in polar solvents.

Example: $NaCl$ in water.
