if you know how to try an atom, a positive atom is an atom that has one less electron then proton and a negative atom is an atom that has one more electron than proton. For the isotopes you draw the same atom but withdifferent numbers of neutrons
B. sodium chloride changed the least; potassium nitrate changed the most.<span />
Answer:
Cost
Explanation:
The cost of purchasing a solar system is high so it serves as a great disadvantage.
Answer:
V = 12.5 L
Explanation:
Given data:
Volume of NO = 15.0 L
Temperature and pressure = standard
Volume of nitrogen gas produced = ?
Solution:
Chemical equation:
6NO + 4NH₃ → 5N₂ + 6 H₂O
Number of moles of NO:
PV = nRT
n = PV/RT
n = 1 atm × 15.0 L / 0.0821 atm.L /mol.K × 273.15 K
n = 15.0 atm.L / 22.43 atm.L /mol
n = 0.67 mol
now we will compare the moles of No and nitrogen gas.
NO : N₂
6 : 5
0.67 : 5/6×0.67 = 0.56
Volume of nitrogen gas:
PV = nRT
1 atm × V = 0.56 mol × 0.0821 atm.L /mol.K × 273.15 K
V = 12.5 atm.L / 1 atm
V = 12.5 L
the hybridization is probably sp2. it will have 1pi bond. There is a double bond between C and O atoms and that double bond consists of 1 pi bond and 1 sigma bond.
