Answer:Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.
Explanation:
Answer:
-2, -1, 0, +1, +2
Explanation:
The quantum numbers describe the quantum state of an electron in an atom. These numbers are symbolized as n, l, m, and s. There are rules for the combination of these numbers. The angular quantum number (ℓ) is related to the magnetic number (<em>m</em>): if ℓ is equal to a number a, thus <em>m</em> can be any integer number between - a and +a.
According to this rule:
If ℓ = 2, thus <em>m</em> can be have a value of an integer between -2 and +2 ⇒ -2, -1, 0, +1, +2
Answer:
Explanation:
molar volume=moles*given volume
for molar concentration we use two formulas molarity and molality
molarity=no of moles/volume
molality=no of moles/kilogram
Answer:
The answer to your question is: 3305.6 g of HNO₃
Explanation:
Data
mass HNO₃ = ?
mass NH₃ = 892 g
Balanced Reaction
2 NH₃ + 4 O₂ ⇒ 2HNO₃ + 2H₂O
MW NH₃ = 14 + 3 = 17g
MW HNO₃ = 1 + 14 + 48 = 63 g
34 g of NH₃ ------------------ 126 g of HNO₃
892 g of NH₃ ------------------ x
x = (892 x 126) / 34
x = 3305.6 g of HNO₃
3p2
The second subshell is p and there are still 2 electrons to be placed
