Honestly, I think a type of substance would be liquid. Orange juice, water, mil can be observed but not identified.

See explanation and image attached
Explanation:
This reaction is known as mercuric ion catalyzed hydration of alkynes.
The first step in the reaction is attack of the mercuric ion on the carbon-carbon triple bond, a bridged intermediate is formed. This bridged intermediate is attacked by water molecule to give an organomercury enol. This undergoes keto-enol tautomerism, proton transfer to the keto group yields an oxonium ion, loss of the mercuric ion now gives equilibrium keto and enol forms of the compound. The keto form is favoured over the enol form.
Answer:
Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.
Answer:
51.1 g NH3
The required chemical reaction is given by:
N2 + 3H2 --> 2NH3
4.5 mol H2 × (2 mol NH3/3 mol H2) = 3 mol NH3
molar mass of NH3 is 17.031 g/mol
3 mol NH3 × (17.031 g NH3/1 mol NH3) = 51.1 g NH3
The two roots of this functions are the exact roots and one is an imaginary root. The -2 is the root of a negative number -16 because if you compute the -2 on its 3rd power you come up -16, the 2 is the root of 16 and the 4+i contains a imaginary number that is why it is an imaginary root
