I was wondering what (I) means when it is written after a chemical compound, for example, H2SO4 (I). Thanks!

In our chemistry class, we learned that an acid is a molecular compound that release hydrogen ions when they are dissolved in water through a process called ionization. So are both Hydrogen Sulfide (g) and Hydrosulfuric Acid (aq) acids?

I'm not sure where this thread should go, sorry if it's in the wrong place. In Newton's thought experiment about the rotating rocks going taut in deep space. With respect to what would the rocks be rotating?

Homework Statement If a stone is dropped over the side of a hot air balloon that is rising at 3 m/s and it strikes the ground 1.5s later, from what height above the ground was the stone dropped Would V1 be 3 m/s or 0.. I'm really confused.

What determines an atom's chemical fingerprint (banding pattern)?

Homework Statement A cyclist is traveling with a speed of 11.0 m/s when she applies the brakes. After slowing for 2.5s, her speed has been reduced to 3.0 m/s. If she continues braking, how much longer will it take her to stop? I found the deceleration to be -3.2 m/s^2 V1 = 3.0 m/s V2 = 0...

I know that the Earth rotates around the sun, but what does our solar system rotate around? P.S. I'm a noob when it comes to anything related to astronomy, sorry.

Ok thanks for your responses and thanks for helping me!

For Newton's thought experiment about two rocks in deep space that will pull taut, with respect to what is it rotating? I'm trying to read Brian Greene's book "The Fabric of the Cosmos" but I'm getting very confused. Forgive me if this is a stupid question.

So, is spacetime only used as a benchmark for accelerated motion?

STUPID QUESTION ALERT! Is spacetime an absolute reference frame?
