Science & Mathematics - 27 November 2007

The answer has gotten confusing now. Back when I was in third grade I learned it as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

Several years later, we were taught that there was a new planet called "Vedna" or something like that.

I've been tuned out of the whole planet thing, but know Pluto is no longer a planet. I look online and it lists the planets as they were back in the day with the original 9. Is Vedna (sp?) a planet or did they demote it to a planetoid? And can anyone confirm that Pluto is definitely not a planet?

I want educated answers please.

How many sodium ions would create a stable compound with how many oxygen ions (look at their charges)? How would you then write the formula?

Okay I really don't want to do my science fair project, so I've made up all the stuff I told my teacher. I told her I was doing a science project about "how does salt water affect plant growth?" We have to give her the conclusion and graphs and tables though. So if you've done this project before or one similar, or if you just know what the growth will be, can you tell me? Or maybe an estimate of normal plant growth over two weeks? I don't need anything excact, just something believable. Thanks.

I am not talking about people who are not knowledable in science and may slip in, but the people who are. Especially the people who have posted their credentials on their profile and have answered several questions in the SM section.

How can their answers be wrong if it is pertaining to science?

Oxygen is often generated in the laboratory by the reaction between sodium peroxide (Na2O2) and water, under appropiate conidtions. Sodium hydroxide is the other product.

Just need help in writing the chemical equation, the rest of the equation in finding grams, volume and etc. I can do! Thank you so much for your help!

I don't want you to tell me the answer. I just want you to tell me what to do.

I got 2 packets and I have 2 question I don't know how to do.

1)What is the mass of a falling rock if it hits the ground with a force of 147 newtons?

2) How do you calculate an average speed?


If you can tell me how to do this (not tell me the answer) I would be thankful.
