Answer:
Given:
Mass = 11.29 g
Volume = 2 cm³
To Find:
Density of unknown metal
Explanation:
Formula:
Substituting value of mass & volume in the formula:
Explanation:
235 U92 + 1n0 --> A + B + 3 1n0
when A = ;
(a) xenon-133
Mass number of B = 235 + 1 - 133 -3 = 100
Atomic number = 92 - 54 = 38
Element = Sr - Strontium
(b) barium-144
Mass number of B = 235 + 1 - 144 -3 = 89
Atomic number = 92 - 56 = 36
Element = Kr - Krypton
(c) cesium-143
Mass number of B = 235 + 1 - 143 -3 = 90
Atomic number = 92 - 55 = 37
Element = Rb - Rubidium
(d) tellurium-137
Mass number of B = 235 + 1 - 137 -3 = 96
Atomic number = 92 - 52 = 40
Element = Zr - Zirconium
(e) lanthanum-146
Mass number of B = 235 + 1 - 146 -3 = 87
Atomic number = 92 - 57 = 35
Element = Br - Bromine
Hydronium ions are basically H+ ions.
So if [OH-]>[H+]
This means that the substance is more basic.
and basic substances a pH>7.
Therefore a possible pH value would be 10.
Answer:
See attached picture.
Explanation:
Hello,
In this case, on the attached picture, you will find the required structure wherein we can see the ethynyl radical at the first carbon which is composed by two carbon atoms bonded via a triple bond due to the "ynyl" suffix. Moreover, the cyclohexane acts as the main chain.
Best.
