<span>(2.09 mL) x (1.592 g/mL) / (227.0871 g C3H5O9N3/mol) = 0.014652 mole C3H5O9N
4 moles C3H5O9N produce 12 + 6 + 1 + 10 = 29 moles of gases, so:
(0.014652 mole C3H5O9N) x (29/4) = 0.106 mole of gases
(b)
(0.106 mol) x (46 L/mol) = 4.88 L gases
(c)
(0.014652 mole C3H5O9N) x (6/4) x (28.0134 g/mol) = 0.616 g N2</span>
Find your element on the periodic table. Locate the element’s atomic number.
Determine the number of electrons. Look for the atomic mass of the element. Subtract (-) the atomic number from the atomic mass
Answer:
7 to 1
Explanation:
As you move from row ----- to row ------ in the periodic table, the atomic radius of the elements DECREASES.?
And we have 7 rows in a periodic table, so the answer has to either 1 to 7 or 7 to 1
Theoretically,
Atomic size increase as we move from top to bottom as an extra shell gets added up with every period.
SO, the answer is, 7 to 1
A is the answerereerrrerrrr
