When the atoms of radioactive elements have an unstable nucleus. As the nucleus tries to become stable, it releases energy (ionizing radiation), and extra protons or neutrons in the form of alpha or beta particles.
Answer:
In given structure of substituted cyclohexane select the "Bromine" atom as the answer.
Explanation:
1,3-Diaxial Interactions:
As cleared from name, this type of interactions are found in cyclic alkanes in which one group present at position 1 (assumed number) experiences steric hindrance due to another group present at position 3.
Also, it is necessary that both the groups must be occupying either axial or equatorial positions respectively. For example, in given structure the methyl group at position 1 is at axial position and another bulky group which should interact with this methyl group must occupy axial position at carbon 3 next to carbon 1. Hence, as shown in figure, the Bromine atom is present at third carbon and is at axial position too.
In attached picture, the green lines indicate steric interactions between Methyl group and Bromine atoms which are involved in steric interactions in 1,3-diaxial fashion.
Answer:
The answer is D. 0.60 L
Explanation:
The balanced reaction equation including states of matter is;
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)
More simple:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
Now, we can see from this reaction equation that the mole ratio of NaOH to H2SO4 is 2:1
Number of moles of H2SO4 reacted = 1.2 moles
Hence;
2 moles of NaOH reacts with 1 mole of H2SO4
x moles of NaOH reacts with 1.2 moles of H2SO4
x = 2 * 1.2/1 = 2.4 moles of NaOH
Recall that;
Number of moles = Concentration * Volume
Volume = number of moles/concentration
Volume of NaOH is obtained from;
Volume = 2.4 moles/ 4.0 M
Volume = 0.60 L
