Answer:
Because they lack chlorophyll (a green pigment in plants that helps them trap sunlight, used to manufacture their food through photosynthesis)
Explanation:
Mushrooms are heterotrophs. They are not plants or autotrophs. Mushrooms, just like every living thing that exists need energy in order to live. Only plants, or autotrophs, can directly use energy from the sun (the ultimate energy) to make food. Those organisms that cannot harness the sun's energy are known as heterotrophs. Mushrooms are fungi (belong to kingdom Fungi) and are heterotrophs because they decompose and consume nutrients from the soil. They are not green so they cannot photosynthesis due to lack of chlorophyll.
Aluminum Al2713 has an atomic molar mass of 27 grams per mole.
Al has 13 protons (hence number 13) and it most common isotope 14 neutrons for a total mass of 27 amu. ( The 13 electrons add no measurable mass to the atom)
Take the grams and divide by the molar mass
= 2 moles

<h3>Answer:</h3>
SALT
<h3>Explanation:</h3>
Salt is formed by the opposite ions bonded to each other through Ionic Bond. The two ions i.e. Cation and Anions are formed by oxidation and reduction reactions respectively. General dissociation of salt is represented as,
MN → Mⁿ⁺ + Nⁿ⁻
where;
Mⁿ⁺ = Cation
Nⁿ⁻ = Anion
MN = Salt
Following is the list of salts which when when dissociates produces Cations and Anions other than OH⁻ (Hydroxide) and H⁺ (Hydrogen Ion).
Magnesium Sulfate:
MgSO₄ → Mg²⁺ + SO₄²⁻
Sodium Chloride:
NaCl → Na⁺ + Cl⁻
Sodium Carbonate:
Na₂CO₃ → 2 Na⁺ + CO₃²⁻
Ammonium Dichlorate:
(NH₄)₂Cr₂O₇ → 2 NH₄⁺ + Cr₂O₇²⁻
Chemical change is when the nature of something changes. Physical change is when a physical component changes.
Chemical change:
- not easily reversible
- new product formed
- reactants are used (two products form a new one e.g iron and oxygen forms rust)
- heat is released/absorbed
Example: Wood burns, it releases heat, produces CO2 and ash and you cannot reverse the burning.
Physical Change:
- easily reversible
- no new products formed
- is often a state change
Example: Ice melts, water is formed, water can freeze again.
