Need practice balancing those tricky equations in Chemistry? Look no further.
This app serves up equation after equation to be balanced, by the time you have completed the app you will be a genius at balancing chemical equations.
Common equations such as photosynthesis and production of ammonia are inside the app as well as more complex equations to balance.
Just drag the numbers into the equation and press submit. The app will check your answer for you.
Really neat concept and it has the potential to be really helpful, however if you don't have the correct answer there's no "hint", review, or assistance to help walk you through what you're doing wrong you just have to skip to the next equation.
All correct solutions deliver an incorrect mark! No answers in the app for students to check on themselves. No correct answer response when equation is successfully balanced! Not good for reinforcement.
A great value app for a buck. 100 typical equations to balance. I think the reviews above, the reviewers need to go back to chemistry class lol They must be balancing the equations incorrectly, I've done all 100 and they are all correct :-)
Correctly balanced equations (and yes I had others check them) return a X and clear the inputs. I am assuming this must mean the apps thinks the answer is wrong. Am I missing something? Why does it mark answers wrong?
This app is helpful IF you know how to use it. I got very frustrated with it at first because it kept telling me I was incorrect when I knew I was right. The trick is to not use the 1's in the equation. I don't know why they offer it (because you can't be correct if you use it) so don't use them when balancing, it will tell you that you're wrong, instead, don't put a number in and it will mark you correct.
Well thanks for not help 99 cents I want back!!!!!! Loser I needed help with my home work and I got was this!!! Who would play this? Not me for sure....grrrr.... If I could I won't have gave it a star SAVE YOUR MONEY
App doesn't respond to your touch, just displays the screen. Don't buy this app.
