  1. H

    Block at rest on an inclined surface

    N is the normal force. (the force that Earth applies)
  2. H

    Block at rest on an inclined surface

    correct me if I'm wrong but I think the component of the applied force along the inclined surface should be ##Mgsinθ## as well (just to the opposite direction).
  3. H

    Acceleration on an inclined plane

    since the 2 masses are connected they should have the same acceleration
  4. H

    Does the initial temperature affect the change in temp?

    I spoke to my Chemistry teacher about it and she said that since NaOH is already VERY soluble in water the increase in temperature shouldn't have a noticeable effect on its equilibrium.
  5. H

    Does the initial temperature affect the change in temp?

    does it matter that solubility increases if in both cases all of the NaOH dissolves? edit: or well not ALL of it but in both cases, it reaches the equilibrium
  6. H

    Does the initial temperature affect the change in temp?

    ok so let me know if I understand right (from what I read in the link you shared). In exothermic reactions - as the initial temperature increases, dH/R becomes smaller hence dH being a smaller value? so if I apply this to the example I gave with NaOH - as I increase the initial temperature of...

    Does the initial temperature affect the change in temp?

    Say I dissolve NaOH in water - a very exothermic reaction. Does it matter if I dissolve it in water that is at room temperature or at a different temperature? Will changing the initial temperature of the water affect the dH of the reaction (hence affect the change in temperature at the end of...
