Explanation: the answer has it's root in Law of mass action which states that; the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients.
organism
population
community

Answer:
2.5 grams
Explanation:
law of conservation of mass applies. the magnesium completely burns
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
Remember the order, <n, l, ml, and ms>.
n: energy level
l: subshell
ml: number of orbitals in the subshell.
ms: electron spin.
The first numbers (n) of both the electrons are the same, but the only difference is the second number (l). The first electron has l=2, indicating that the electron is in the "d" subshell. On the other hand, the second electron has l=1, indicating that the electron is in the "p" subshell.
*Remember*
l=0 (s) spherical shape
l=1 (p) peanut shaped
l=2 (d) clover
