Answer : The mass percentage of isopropyl alcohol in the solution is, 59.4 %
Explanation :
To calculate the mass percentage of isopropyl alcohol in the solution, we use the equation:
Mass of isopropyl alcohol = 6.68 g
Mass of isopropyl alcohol solution = 3.97 g
Putting values in above equation, we get:
Thus, the mass percentage of isopropyl alcohol in the solution is, 59.4 %

Answer:
Alloy
Explanation:
Alloy: An alloy is a substance prepared by adding one or more element to a base or parent metal to obtain desirable products. The added element are usually metals or carbon. An alloy can be considered as a uniform mixture.
Examples of Alloy:
⇒ Brass is an alloy that contains 60 - 80% of copper and 20- 40% of zinc.
⇒Bronze is an alloy that contains 90% of copper and 10% of tin.
⇒ Steel is an alloy that contains 99.8% of iron and 0.2% of carbon.
Uses of Alloys:
⇒ They are used for making coins and medals
⇒ They are used in the construction of aircraft, ships and cars.
⇒They are used for making electromagnet.
Answer: The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted. The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of rocks. As the lava cools it hardens and becomes igneous rock. As soon as new igneous rock is formed, the processes of weathering and erosion begin, starting the whole cycle over again!
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!
