When you drop iodine on a leaf you may observe a colour change of orange/brown to a blue/black complex.
This is because in the leaf there are starch molecules that form a blue/black complex with the starch molecules.
hope that helps :)
Answer:
D. Malleability
Explanation:
Gold is made up of the element Au and it is a metal.
Pyrite is iron sulfide and it is a non-metal.
- They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
- To distinguish between the two, we simply explore their metallic properties.
- Gold is malleable. Pyrite is not. It will crumble under pressure.
Answer:
Mixtures
Explanation:
Matter can be classified as a compound and a mixture.
The artificial fixation of nitrogen (N2) has enormous energy, environmental, and societal impact, the most important of which is the synthesis of ammonia (NH3) for fertilizers that help support nearly half of the world's population.
<h3>Artificial fixation of nitrogen</h3>
a) The equilibrium constant expression is Kp=PCH4 PH2 OP CO×PH 23.
(b) (i) As the pressure increases, the equilibrium will shift to the left so that less number of moles are produced.
(ii) For an exothermic reaction, with the increase in temperature, the equilibrium will shift in the backward direction.
(iii) When a catalyst is used, the equilibrium is not disturbed. The equilibrium is quickly attained
