On a molecular level there is a lot of movement which in turn is the reason why heat is generated.
Answer:
The FALSE statement is: It requires CO2.
Explanation:
Photophosphorylation is a process during which solar energy, in the form of a proton, impact on chlorophyll, exciting one electron. The excited electron pass along different carriers (Ferredoxin, cytochrome b6f and Plastocyanin) and eventually return to its origin. This electron passage promotes the formation of ATP from ADP (one molecule ATP is formed when three electrons pass throug the cycle).
Answer:
1. How do metals and non-metals react with acids?
Ans : Non metals does not react with acids while metals react with acids and produce hydrogen gas that burns with a 'pop'sound.
2. Write and explain the chemical equation for the reaction of magnesium with sulphuric acid and aluminium with hydrochloric acid.
Magnesium + sulphuric acid = Hydrogen + salt
Mg(s) + H2SO4 (aq) MgSO 4(aq) +H2 (g)
Aluminium + Hydrochloric acid = Hydrogen + Aluminium chloride
2Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)
Concrete is formed of sand. Is it incorrect to suggest that some houses are built using concrete blocks?
It is because due to the movement of the plates, natural diasters such as earthquakes take place on the earths surface.
hope this helps you
