    Paper 5 question!

    you dont have to exactly plot it just estimate what type of graph it will be. You can either make it a increasing curve or linear straight line as solubility increases as temprature increases

    You have to mug up some angles like ammonia 109.5 tetrahydral, water 104.5, Bf3 120 triagular . These are similar then to find out the bond angels compare with these and youll find out. Just compare the lone pairs of with them which ever matches bond angle is that.

    by increasing the capactaince Or the resistance. It leads to faster time constant CR so it will discharge faster and smoothing will be increased.
