Answer: The answer is the second choice.
Explanation:
<span>the same
The formula for starch is C6H10O5 which has a ratio of 10 to 5 which reduces to 2 to 1 for the hydrogen to oxygen ratio. The formula for water is H2O which also has the ratio of 2 to 1 for hydrogen. Since the ratios are the same, the answer to the question is "the same". The name used for the category of nutrient that starch falls under should give a strong clue to the chemical formula. It's carbohydrate.</span>
Answer:
p orbital.
Explanation:
Valence electrons are the electrons in an atom holding the very last orbital which is used in chemical bonding with other elements. Their existence could define the chemical properties of that atom.
During the first energy in ionization of an N2 molecule the molecular orbital from which the electron could be extracted is the only one with the highest energy level. Nitrogen has its outermost orbital (p) containing three valence electrons. Each orbital is only half filled, and thus it is unstable Thus, the electron mission must have been removed from p orbital.
Answer:
[H₂SO₄] = 0.255M
Explanation:
H₂SO₄ + 2KOH => K₂SO₄ + 2H₂O
2(M x V)acid = (M x V)base => M(acid) = (M x V)base /2·Vacid
[H₂SO₄] = (0.5M)(25.5ml)/2(25.0ml) = 0.255M
