Explanation:
water near where a river enters the ocean is having a higher density.
coz, ocean water has salt which increases water's density
Answer:
Explanation:(1)base are slippery to touch e.g sodium hydroxide NaOH(aq)..
(2) They can be corrosive e.g pottasium hydroxide KOH(aq) and sodium hydroxide NOH(aq)
(3) They can act as electrolytes e.g NaOH(aq)
(4) they react to acids to form salt and water
Na0H(s)+HCL(aq)>>>NaCL(a)+H20(l)
(5)they dissolve in water to form hydroxyl ion
KoH(aq) >>>>>k+ + 0H-
It is a reaction that requires heat as a reactant.
Explanation:
molecular collisions. reactant particles must collide with one another before any reaction can occur.
activation energy. colliding particles must possess a certain minimum total amount of energy if the collision is result in reaction.
The trajectory of their motion knocked the Earth into a different orbit.
