- How would you calculate the Δx for a baseball with mass 145 . . . - Socratic
How would you calculate the Δx for a baseball with mass 145 g with Δv = 0 100 m s? Chemistry Quantum Mechanical Model of the Atom Heisenberg Uncertainty Principle
- Question #33eb8 - Socratic
Let's call the number of weeks we are looking for: w We can then write a formula: $145 + $36w = $433 And we can now solve for w: First, subtract $145 from each side of the equation to isolate the w term while keeping the equation balanced: $145 − $145 + $36w = $433 − $145 0 + $36w = $288 $36w = $288 Now, divide each side of the equation by $36 to solve for w while keeping the equation
- Question #5d6cd - Socratic
Notice that the reaction ended up producing 145 g of xenon tetrafluoride This represents the reaction's actual yield, i e what you actually get by doing the reaction in the lab
- How do you add (-8-9i)+(3-6i) in trigonometric form? | Socratic
For a complex number a +bi we can repesent this in trigonometric form, as z = r(cosθ +isinθ) r = √a2 + b2 θ = arctan(b a) So, for z1 = − 8 − 9i, we can find that r1 = √(− 8)2 +(−9)2 = √145 θ1 = arctan(−9 −8) However, −8 − 9i is in quadrant 3, but θ is in quadrant 1, so we need to add π θ1 = arctan(−9 −8) +π ≈ 3 9857 z1 ≈ √145(cos(3 9857) + isin(3 9857
- What is the equation of the line with slope - Socratic
The equation of a line in slope-intercept form is y = mx + b We are given x, y, and m So, plug these values in: 11 = 12 11 ⋅ − 2 + b 11 = − 24 11 + b 11 + 24 11 = b 121 11 + 24 11 = b 145 11 = b This is how I would leave it but feel free to turn it into a mixed fraction or decimal So, our equation is y = (12 11)x + 145 11
- Question #48bcb + Example - Socratic
From this, the number of unpaired electrons seems to be: Number of unpaired electrons = S |ms| = 2 145 1 2 = 4 29 ≈ 4 So it looks like treating μS+L ≈ μS for Fe2+ is OK to determine the number of unpaired electrons For Fe3+ it should be that μS+L = μS perfectly, since the 3d is half-filled there
- Question #5b826 - Socratic
["Br"_2]_(eq) = "0 0108 M" ["Cl"_2]_(eq) = "0 0108 M" ["BrCl"]_(eq) = "0 0284 M" What we're really doing here is that we're given an initial state with ["BrCl"]_i = "0 050 M", and we're given K_(eq), which is defined for a final state we define as equilibrium, when the rate of the forward reaction is equal to that of the reverse reaction Concentrations are a matter of "what did we start with
