Answer is: <span>the missing daughter nucleus is rhodium (Rh).</span>
Nuclear
reaction: ¹⁰⁶Ru → ¹⁰⁶Rh + e⁻(electron) +
ve(electron antineutrino).
Beta decay is radioactive decay in which a beta
ray and a neutrino are emitted from an atomic nucleus.There are two types of
beta decay: beta minus and beta plus.
<span>In beta minus decay,
neutron is converted to a proton and an electron and an electron antineutrino.
In beta plus decay, a proton is converted to a neutron and positron and an
electron neutrino, so mass number does not change.</span>
Answer:
The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.
Explanation:
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bond
Between 0.4 and 1.7 then it is Polar Covalent Bond
Greater than 1.7 then it is Ionic Bond
For Fe and S,
E.N of Sulfur = 2.58
E.N of Iron = 1.83
________
E.N Difference 0.75 (Polar Covalent Bond)
When a pure solid Z sample it a covalent compound is heated continually for 11 minutes it will undergo disintegration leaving the bonds intact.
<h3>What is a covalent compound?</h3>
A covalent compound is a compound that is made up of molecules which share one or more pairs of valence electrons and are bonded together by a covalent bond.
One of the major factors that affect compounds with covalent bonds is temperature.
The increase in temperature during heating leads to the separation of the atoms from each other but leaving the bonds intact.

In a given solution, the concentration of hydrogen ions and hydroxide ions are related to each other by the following expression:
pH + pOH = 14
where, pH = - log[H+] and pOH = - log [OH-]
In this case, the concentration of sulfuric acid is given as 2.1 x 10^-4 M. Since each molecule of sulfuric acid (H2SO4) contains 2 atoms of hydrogen, the concentration of hydrogen ions in this solution is twice that of sulfuric acid. That is,
Concentration of H+ ions = 2 x 2.1 x 10^-4
= 4.2 x 10^-4 M
This means, pH = -log (4.2 x 10^-4) = 3.38
Since pH + pOH = 14
pOH = 14 - 3.38 = 10.62
This means, 10.62 = -log [OH-]
Solving the equation, we get [OH-] = 2.4 x 10^-11 M.
Hope this helps.
The molarity of the solution will be 4.97 M.
<h3>What is molarity?</h3>
It is the number of moles of solutes per 1 liter of solvent or solution.
Mole of 34.1 g NaCl = 34.1/58.44 = 0.5835 mol
117.3 mL = 117.3/1000 = 0.1173 L
Molarity of the solution = 0.5835/0.1173 = 4.97 M
