I'm a first year student taking general chemistry 1

Is their a method for predicting the molecular shape of molecules without drawing the Lewis structure? I am preparing for an ACS exam and would like to try to save some time on these problems. I think I could determine the steric number by counting the total electrons available, and...

Is anyone familiar with any chemical reactions that release both oxygen and carbon dioxide gas as products? Or any reactions where oxygen and carbon dioxide are both reactants? Thanks.

Sorry, I figured it out. When i squared my y value, i only squared the √2, giving me 2, instead of squaring -2√2 which would give 8.

Homework Statement Write the equation of a parabola passing through the point (2,-2√2) and opening to the right. Homework Equations Parabola with a horizontal axis and vertex (0,0) y^2 = 4cx The Attempt at a Solution Since the parabola opens right I will use the equation y^2 =...

Sorry, yes the degree is 2, I typed the wrong number. Thank you for the quick response. * I will correct that in the original posting, as it was a repeated typo

Homework Statement Find the horizontal asymptote(if there is one) using the rule for determining the horizontal asymptote of a rational function for (x^2+x-12)/ (x^2 -4)Homework Equations The Attempt at a Solution the degree of the numerator and denominator are both 2. Y=(An)/(Bn) Y=1/1 Y=1...

Did you try graphing the equations and finding where they intercept?

Sorry. I am using a TI-84 Plus graphing calculator. To graph a vertical line: Hit the [2ND] key followed by the [PRGM] key. This brings you to the menu: 1: ClrDraw 2: Line( 3: Horizontal 4: Vertical 5: Tangent 6: Draw 7: Shade 8: DrawInv 9: Circle( 0: Text( A: Pen select Vertical by pushing...

just found the answer. [2ND] [PRGM] [4] X=[A]

Is it possible to graph a vertical line such as X=2 on a graphing calculator? How would one graph a vertical line on the graphing calculator?
