<span>will metal do is when they ionize they have relatively high energies.These atoms have large diameters. The outer electrons are relatively far from the nucleus. Metals tend to lose electrons and form positive ions.</span>
The chemical Formula Fe(NO2)3 represents the compond iron (lll) nitrate. The compound contains 1 atom of iron represented by Fe, three atoms of nitrogen rep. by N and 6 atoms of oxygen, rep. by O.
Answer:
<u>3.16 liters O2</u>
Explanation:
I'll assume the C3H3 is really supposed to read C3H8, for propane.
C3H3(g) + 5 O2 (g) + 3 CO2 (g)+ 4 H20 (g)
<u>C3H</u><em><u>8</u></em><u>(g) + 5 O2 (g) + 3 CO2 (g)+ 4 H20 (g)</u>
It is unlikely that all the gases involved in this reaction will remain at STP due to the large amount of energy released, we'll assume STP since:
1) We are told STP and no other information is given, and
2) STP makes the problem much easier, since all gasses occupy 22.4 liters per mole of that gas.
The balanced equation tells us we need 5 moles of O2 for every 1 mole of C3H3: a molar ratio of 5/1 (moles O2/moles C3H8).
Calculate moles C3H8 in 0.632 liters of the stuff [metric term for compound]:
(0.632 liters)/(22.4 liters/mole) = 0.0282 moles C3H8
This means we'll need 5 times that number for the amount of O2 required. That comes to 0.1411 moles O2.
Convert that to volume: (0.1411 moles O2)*(22.4 liter/mole) = 3.16 liters O2
Answer:
24.7 grams H₂O
Explanation:
To find the mass of water, you should (1) convert from grams HCl to moles (via molar mass from periodic table), then (2) convert from moles HCl to moles H₂O (via mole-to-mole ratio from equation), and then (3) convert from moles H₂O to grams (via molar mass from periodic table).
1 HCl + KOH --> 1 H₂O + KCl
Molar Mass (HCl): 1.008 g/mol + 35.45 g/mol
Molar Mass (HCl): 36.458 g/mol
Molar Mass (H₂O): 2(1.008 g/mol) + 16.00 g/mol
Molar Mass (H₂O): 18.016 g/mol
50 g HCl 1 mole HCl 1 mole H₂O 18.016 g
-------------- x ------------------ x ------------------- x ------------------- = 24.7 g H₂O
36.458 g 1 mole HCl 1 mole H₂O
