I was hoping for something a little more general, Bipolarity. As in, how can one tell whether or not there is a reaction, without googling to find out.

Homework Statement sodium oxide plus water --> ? Is there a reaction? Homework Equations sodium oxide plus water yield sodium hydroxideThe Attempt at a Solution Na2O + H2O --> 2NaOH I don't understand whether or not there is a reaction. The problem does not give any states of matter, so how...

That's true, I was less worried about the sig. figs here, I just wanted to make sure I grasped the concept. It's actually 119.5, I just rounded to 120 to make it easier. I never would have thought of the problem in that way, I'll be sure to try to spot such things in the future. :smile:

Excellent, thank you! :approve:

Which numbers are unclear? I think I have the procedure down, I want someone to verify the solution if possible though. :shy:

So was my attempt incorrect? The PDF I attached shows my work.

Homework Statement CH4(g) + 3cl2(g) ----> CHCl3(g) + 3HCL(g) How many grams of CH4 is needed to produce 50.0 g CHCL3 ? For this problem, I'll assume Carbon = 12 amu, Hydrogen = 1 amu, and CL = 35.5 amu.The Attempt at a Solution See the attachment (A PDF file), for my attempt @ the solution...

Homework Statement Sally sue and her partner hold a spring 4 meters apart. There were 5 nodes in the standing waves produced. Sally moved her hand from the rest position back and forth along the floor 20 times in 4 seconds. F Homework Equations The Attempt at a Solution Since...

That makes sense. Silly me, I forgot about that.. Thank you! I'll be sure to use that list of formulas.

Using that I got .89 seconds.. I wonder why my solution is incorrect though. And sorry about the messed up formatting, I didn't realize it was like that.. After all that effort i put into use the TEX code.. oh well. Why would this not work? All I'm doing is substituting variables. A = 10m/s...

Homework Statement You drop a ball (0.5kg( from a height of 4m. How long did the ball take to hit the ground? Homework Equations Assume that initially the velocity is 0 for the following equations below. \DeltaPosition = \Delta Velocity * \Delta Time Acceleration = \Delta Velocity / \Delta Time...

Homework Statement You drop a ball (0.5kg) from a height of 4m. How long did the ball take to hit the ground? Acceleration = -10 due to gravity. Homework Equations \Deltax = Area Under a Velocity-Time graph. ^ In this case, it will be .5*Velocity*Time. The Attempt at a Solution Acceleration =...

It's actually accelerating at 2m/s, upwards. The person weighs 80kg. What would be greater; Fgrav or Fss. And if I have one of the forces, fgrav or fss, how could I obtain the missing force?

Homework Statement I'm quite confused with the material that has been presented to me in my physics class. The scenario is: There is a person that is riding an elevator that is traveling upwards. Draw a free body diagram for the person. (Is Fnorm larger than Fgrav?) Homework...

Homework Statement What is the vertical intercept of an acceleration force graph mean? Homework Equations The Attempt at a Solution The mass of an object with no force applied? That's my guess. Any advice and tips appreciated.
