The answer is D because they would have to make quarries just below the surface to mine
Mineral ores much quicker (Quarries- a large hole/pit under ground used to get stone and minerals)
Answer:
D.Salad
Explanation:
A mixture is a substance that combines two or more substance that are physically combined. A mixture can be easily seperated by a physical means . A mixture is the combination of various substances that are not chemically combined .Examples of mixtures are cake and salad . The cake contains various substances like egg, flour and sugar. This mixture can be easily separated into it individual entities by a physical means .
Base on the option the only mixture among the option is salad . Salad is a a mixtures that combines substances like tomatoes , fruits and vegetable. The individual substances that makes up the salad can be easily separated.
Sugar is a compound . Water is a compound as it contains two elements and potassium is an element.
1. 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂
2. CH₄ + 2O₂ → CO₂ + 2H₂O
3. Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag
4. MnO₂ + 4HCl → MnCl₂ + 2H₂O + Cl₂
5. Pb(NO₃)₂ + 2NaCl → PbCl₂ + 2NaNO₃

Gases near together and vibrate in position however, don't circulate beyond each other. In a liquid, the particles are interested in every different but now not as a great deal as they may be in a strong.
The particles of a liquid are near together, constantly transferring, and may slide beyond one another. The Kinetic-molecular concept attempts to explain the behavior of fuel molecules based totally on the nature of gasoline. The principle is grounded on simple assumptions
In gases the debris passes swiftly in all directions, regularly colliding with every different facet of the box. With a boom in temperature, the debris gains kinetic strength and passes more quickly. Gasoline is a state of matter that has no constant form and no fixed extent. Gases have a decreased density than other states of the count, together with solids and liquids. there may be a high-quality deal of empty area between debris, that have loads of kinetic energy and aren't especially drawn to one another.
