The two liquids made a new substance.
<h3>What is a physical and chemical change?</h3>
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
A chemical change occurs when some substances are transformed into different substances, with different nature and properties. In this case when both liquids are mixed a solid is formed. This is an example of a change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture which is called a chemical change.
Hence, option D is correct.

Answer:
Hypsochromic compound, More polar solvent
Explanation:
Hypsochromic shift refers to the shift of solution colour to blue side of the visible spectrum (blueshift) with increasing polarity of the solvent. In our case, the solution changes to orange colour from red when solvent is changed. This means that the emission spectrum of the solution underwent blueshift. (As orange colour is on the 'blue' side for red colour.) So this is a hypsochromic shift, and the new solvent is more polar that the previous one, as it caused hypsochromic shift.
Rocks are heated, metamorphosed, melted,
weathered, sediment is transported, deposited and lithified, then it may be metamorphosed
again in yet another cycle. This recycling of the material of the Earth's crust has
been going on for billions of years, as far back as there is a preserved geologic record
(about 4 billion years). Weathering and erosion at the Earth's surface can break
down rocks into small bits. These can be
deposited as sediments that become sedimentary
rocks. Burial, with rising pressure and temperature, can alter sedimentary (as well as any
other) rocks to form metamorphic rocks.
Continued rise in temperature can eventually melt
rocks and produce magma. Cooling of magmas leads to igneous rocks, etc.
is the symbol of the species with 23 protons and 21 electrons.
Hence, option F is correct.
<h3>What is a proton?</h3>
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge.
If it has 23 protons, then its proton number (also know as its atomic number) is 23. You can look that symbol up in your periodic table.
If it has 21 electrons then it has a net charge of 23(+) - 21. So we know the ionisation state of the species, and we can record that as a superscript after the symbol for the species.
Hence, is the symbol of the species with 23 protons and 21 electrons.
