Answer:
O2
Explanation:
for find the limiting reactant you must calculate the moles of the reactants from the amount that you have and from the MM:
MM FeS2 = 120n = 26.2g / 120g/mol = 0,218 mol
MM O2 = 32n = 5,44g/32g/mol = 0,17 mol
The limiting reactant is
O2
The number of grams of NaCl required to make 150.0 ml of a 5.000m solution is 43.875 grams
<u><em>calculation</em></u>
Step 1: calculate moles of NaCl
moles= molarity x volume in liters
volume in liters = 150.0 ml/1000= 0.15 l
moles is= 5.000mol/l x0.15 l =0.75 moles
Step2 : find mass
mass= moles x molar mass
molar mass of NaCl= 23 +35.5 = 58.5 g/mol
mass= 0.75 moles x58.5 g/mol = 43.875 grams
It is completely dependent on the type of light bulb you are talking about. There are many different kinds of light bulbs, I cant give you a solid answer.
Answer : Option C) It explained the odds of finding the position of an electron.
Explanation : Schrödinger's theory of the atomic model is true for the probability of finding the electron around the nucleus. Schrödinger used odd mathematical equations to describe the likelihood of finding an electron in a certain position around the nucleus. This atomic model was known as the quantum mechanical model of the atom. He posed an equation which is now called as the Schordinger’s Wave Equation, which incorporates both the wave-like and particle-like behaviors of electrons, which stated that electrons can act like waves/light and particles. Which later helped to develop the uncertainty principle for finding the probable position of the electron.
