Like most liquids, mercury expands, or gets bigger, when heated. As the environment gets warmer, the expanding mercury inside the narrow glass tube of the thermometer has nowhere to go but up. When the temperature cools, the mercury slides back down the tube.
the new volume is calculated by use of Boyles law formula
that is P1V1=p2v2
v2= p1v1/p2
P1= 720 mmhg
v1= 1500ml
p2 = 2 atm
V2=?
convert P2 to mmhg = 2 x760= 1520 mmhg
V2= 720mmhg x1500 ml/ 1520mmhg = 710.53 ml
Salt is usually formed during neutralization reactions,
that is the reaction of an acid and a base. This is illustrated as follows:
<span>HX + YOH --> XY
+ H2O</span>
where XY is the salt
From the given choices, the only pair of acid and base is:
<span>Vinegar and antacids</span>
