The hotter water is less dense and rises. The cooler water then sinks because it is more dense.
Answer:
Natural phenomena such as melting glaciers is due to the rise in temperature. This will result to extinction of flora and fauna. Moreover it can cause extreme flooding due to rise in water level in other water bodies such as rivers, lakes
Answer:
Option O = H₂O
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
In this balanced chemical equation we can see that water is the only compound that consist of two hydrogen atom and one oxygen atom. H : O
2 : 1 .
In case of KOH two hydroxyl and two potassium atom are present and ration is K:OH 1:1.
Answer:
Explanation:
V1/T1 =V2/T2 at constnant pressure
Answer:
E.
Explanation:
Look at change in concentration over time...is it increasing or decreasing? It is increasing right as you can see because it starts at 0 then increases and plataeus. What increases in a reaction, reactant or product? Products increase right cuz your reactants react with each other to make prodcuts.
At start of reaction you have no products (zero) thus this graph starts at 0. At end you have alot of product thus over time the concentration of product increases.
ABC are reactants their concentration should decrease over time
DE are products, they should increase as reaction goes on.
