Answer:
109° 27'
Explanation:
The ammonium ion is tetrahedral in shape, all the HNH bonds are exactly at the tetrahedral bond angle since there are only bond pairs in the structure and no lone pairs. Recall that lone pairs decrease the bond angke from the ideal value in a tetrahedron due to higher repulsion.
The cellular component responsible for energy production and metabolic processes is mitochondria.
What is Mitochondria?
A double-membrane-bound organelle known as a mitochondrion is found in the majority of eukaryotic organisms. The majority of the cell's adenosine triphosphate, which is then used as a source of chemical energy throughout the cell, is produced by mitochondria using aerobic respiration.
Oxidative phosphorylation, which produces ATP using the energy released during the oxidation of the food we eat, is the traditional function of mitochondria. For the majority of biochemical and physiological processes, including growth, mobility, and equilibrium, ATP is used as the main energy source in turn.

Answer:
The presence of Br atom produces 2 ions (M and M+2) with the same abundance.
Explanation:
Mass spectrometry is an instrumental technique in which chemical substances are ionized and fragmented. The nature of the substances produce different fragmentations.
A way to know if a substance contains bromine is seeing the parent molecular ion (M, Subtance with ⁷⁹Br) and M+2 (Substance with ⁸¹Br) with the same relative abundance. Where parent molecular ion is the substance without fragmentations
<em>That is because in nature, the isotope abundance of bromine is ⁷⁹Br with 51% and ⁸¹Br with 49%, producing the 49% of ions having 2 units of m/z higher than its consecutive ion.</em>
