71.8 g of iron (III) oxide (Fe₂O₃) were produced from 3 moles of magnesium oxide (MgO).
Explanation:
We have the following chemical reaction:
2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂
We see from the chemical reaction that 3 moles of magnesium oxide (MgO) will produce 1 mole of iron (III) oxide (Fe₂O₃).
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of Fe₂O₃ = 1 × 71.8 = 71.8 g

By integrating two or even more materials whose properties are quite distinctive is composite materials. The different materials work together to build special properties for the composite, but within the composite one can easily tell the various materials apart that they don't dissolve or mix together.
It is also recognized as Fiber-Reinforced Polymer (FRP) composites, which are constructed from a polymer matrix strengthened with engineered, man-made or natural fiber like glass, steel or aramid or other strengthening material.
- Their high dimensional consistency helps them to preserve their shape, be it hot or cold, wet or dry.
- This renders them a common material for outdoor frameworks such as wind turbine blades.
- These have less resistance to cracking than metals but more durability than most polymers.
Answer:
A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".

Answer:
The correct answers are "They travel slower than P waves", "They result in much ground motion" and " They are produced by P and S waves".
Explanation:
A surface wave can travel through the existing interface between Earth and air, as well as between Earth and water. A clear example of this type of waves are Love and Rayleigh waves. They travel slower than primary waves, produce large movements in the ground and are produced by primary and secondary waves.

Answer:
0.75 cm
Explanation:
You will convert 1.07 carat into mg then into g. You will multiply its reciprocal by 3.51g/cm to get the answer.
