Answer:
B one mole of carbon is lighter than one mole of magnesium
True
As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond
When it would be on a flat area with no slope. and no movement
In this question, you are given the NaOH volume but asked for concentration.
Don't forget that for every 1 mol of NaOH there will be 1 mol OH- ion, but for every 1 mol of H2SO4 there will be 2 mol of H- ion.
To neutralize you need the same amount of OH- and H+, so the equation should be:
OH-= H+
<span>35.50cm3 * x*1= 25cm3* 0.2mol/dm3 *2
</span>x= 10/35.5 mol/dm3= 0.2816/dm3
