I'm sorry if this doesn't answer this correctly but solid liquid solider solid liquid/solid
The answer is Desert. The <span>biomes that likely has the thinnest layer of topsoil is the Desert. </span>The topsoil is a very important layer of soil because on this <span>layer of soil, plants are nourished. The topsoil have to be healthy to grow plants on it. It contains humus, bacteria, fungi, insects and worms.</span><span> But you can hardly find these in the Desert.</span>
Answer:
The temperature of the mixture is 60°C
Explanation:
We can write the energy of water as follows:
E = m×C×T
<em>Where E is energy in Joules, m is mass of water, C is specific heat of water = 4.184J/g°C and T is temperature</em>
<em />
Replacing fot both samples:
E = 20g×4.184J/g°C×30°C
E = 2510.4J
E = 40g×4.184J/g°C×75°C
E = 12552J
The total energy of the mixture is 12552J + 2510.4J = 15062.4J
Mass = 60g:
15062.4J = 60g×4.184J/g°C×T
60°C = T
<h3>The temperature of the mixture is 60°C</h3>

Compound versus Element comparison chart
Compound Element
Definition A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom.
Representation A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound. An element is represented using symbols.
Composition Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined. Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.
Examples Water (H2O), Sodium chloride (NaCl), Sodium bicarbonate (NaHCO3) etc. Hydrogen (H), Oxygen (O), Sodium (Na), Chlorine (Cl), Carbon (C), Iron (Fe), copper (Cu), silver (Ag), gold (Au) etc.
Ability to break down A compound can be separated into simpler substances by chemical methods/reactions. Elements cannot be broken down into simpler substances by chemical reactions.
Types A huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes. There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.
