<span>Specular reflection, or the act of seeing ones self in the mirror, is an everyday part of science that we commonly use without much thought about it. This is basically a reflection of light off a reflective surface, the image does not scattered but is printed on the surface for you to see.
Though quantum mechanics may explain how a magnet works scientist really have no true understanding of why charged particles create magnetic fields when they are moved around.
The microwave oven is another form of everyday thing that casually uses science. The science behind it is called electromagnetic energy. Basically it operates on a micro frequency that passes nearly harmlessly through plastics, glass, ceramics, etc to stimulate the atoms in liquids and meats to a reaction point that cooks them. Of course these micro waves also over stimulate metals thus why metal in the microwave is very bad.</span>
Answer:
M₂ = 1.9 M
Explanation:
Given data;
Volume of sodium chloride = 200 mL
Molarity of sodium chloride = 4.98 M
Volume of water = 532 mL
Final Molarity = ?
Solution:
M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 4.98 M × 200 mL / 532 mL
M₂ = 996 mL. M /532 mL
M₂ = 1.9 M
