Answer:
Explanation:
Hemoglobin removes excess protons from the red blood cells so that they can be excreted through the kidneys.
Hemoglobin binds some of the excess protons released by carbonic acid.
Subsequent binding of oxygen is drastically reduced after the first one is bound.
Hemoglobin produces protons or hydroxide ions as needed to alter the blood pH.
To determine the number of atoms present in the given number of moles of sodium which has a chemical formula of Na, we multiply the number by the Avogadro's number, 6.022 x 10^23. That is,
number of atoms = (36 mol) x (6.022 x 10^23)
= 2.16792 x 10^25 atoms of Na
Maple syrup would be categorized under solutions. As it contains sugar which is very soluble in water, it dissolves completely in water depending on its solubility at that temperature making it impossible for the components to be filtered out. A solution is a homogeneous mixture.
Answer: Temperature of the water is 40
Reaction time: 26.3
Explanation: literally just press the tongs in the workslide!
Valance electrons are the extra electrons on the outermost orbital, that hasn't been filled yet. For example, Lithium would have one valence electron, on the 2s orbital, because that is an extra electron floating around that 2s orbital, that can be shared with others, since each element's goal is to have no valence electrons. If an orbital is filled, it therefore has no valence electrons, because valence electrons are only extra electrons, if that makes any sense.
There are many groups of the periodic table. These groups categorize electrons by the amount of valence electrons they have. The group on the far left, the alkali metals, all have one valence electrons. The alkali metals include Lithium, Sodium, and other elements, so therefore give away that one electron easily, because if they give it away they won't have any valence electrons. (This is why you often see salt, sodium chloride, because sodium gives away its one valence electron to chloride, who needs one electron to have no valence electrons.) One other notable group is the noble gases, on the far right of the periodic table. These elements have no valence electrons, so therefore won't bond easily with other elements.
Hope this helped!
