2 km since they walked 5km but then walked back 3km so it would be 5 - 3 = 2
Mitochondrial is relating to or characteristic of a mitochondrion or mitochondria is the answer
I hope this helps and have a nice day
The Alkali Metals- (Group 1A)can be found (excluding hydrogen) in the first column of the periodic table. They all have 1 valence electron and tend to form +1 cations when forming Ionic bonds with non metals.
The Alkali Earth Metals: (Group 2A) can be found in the second column/group on the periodic table. These elements form +2 positively charged cations when forming Ionic bonds with non metals. They also all have 2 valence electrons.
The Halogens: are the elements that make up the second to last group on the periodic table. These elements include Chlorine, Fluorine, Bromine, Iodine, and Astatine. These elements have 7 valence electrons. The usually form a -1 charged anion when forming ionic bonds with metals.
The Noble gases: the very last group on the periodic table. All these elements have 8 valance electrons. Due to the octet rule these atoms are already very stable and rarely react with other elements.
Answer:
Explanation:
The decomposition of follows the equation
By definition, the rate of a chemical reaction can be expressed by
The rate of appearance of is related to the rate of disappearance of by the stoichiometry. This means that, for each mole of that appears 2 moles of are consumed. So
