Answer:
Pentane reacts with oxygen in a combustion reaction to produce carbon dioxide and water. C5H12 + O2 -> CO2 + H2O If you have 5.00 moles of pentane, how many moles of water will be produced? Hexane combusts in the presence of oxygen to produce carbon dioxide and water.
Explanation:
Answer:
ions are surrounded by hydrogen ends with positive partial charge. In this way the salt is dissolved in water. Sugar is a molecular compound formed by covalent bonds. In a polar covalent bond, electrons are shared unevenly

Answer:
Volume of ammonia 3 L.
Explanation:
Given data:
Temperature = 25°C ( 25+273= 298 k)
Pressure = 99.5 kpa (99.5/101 = 0.98 atm)
Volume of nitrogen = 1.50 L
Volume of ammonia = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Moles of nitrogen:
PV = nRT
n = PV/RT
n = 0.98 atm × 1.50 L / 0.0821 atm. L/mol. K × 298 K
n = 1.47 /24.5 /mol
n = 0.06 mol
Now we will compare the moles of nitrogen with ammonia.
N₂ : NH₃
1 : 2
0.06 : 2×0.06 = 0.12 mol
Volume of ammonia:
PV = nRT
V = nRT/P
V = 0.12 mol× 0.0821 atm. L/mol. K × 298 K/ 0.98 atm
V = 2.9 atm. L /0.98 atm
V = 3 L
C. because silvers atomic number is 47 so you subtract 47 from 107 to get the number of neutrons
