What does the chemical formula caci2 show about the compound it represents? Answer: Two elements because Can is one element and Cl is another. The two is a coeficient that states how many of that element there is. I hope this helps you!!! What does the four mean in the formula 4na2so3? The ‘4’ in […]
Why do grain boundaries act as barriers to dislocation motion?
Why do grain boundaries act as barriers to dislocation motion? Since the lattice structure of adjacent grains differs in orientation, it requires more energy for a dislocation to change directions and move into the adjacent grain. The grain boundary is also much more disordered than inside the grain, which also prevents the dislocations from moving […]
Is the law of reflection applicable to all mirrors?
Is the law of reflection applicable to all mirrors? It is a fact that laws of reflection are applicable to all reflecting surfaces. Is law of reflection valid for all kind of mirror? The laws of reflection hold good for all the mirrors irrespective of their shape (i.e. flat or curved). The angle of incidence=angle […]
Which best describes the relationship between displacement and distance traveled?
Which best describes the relationship between displacement and distance traveled? Displacement is a vector quantity describing the change in position, and distance traveled is the total length travelled c. Displacement is scalar quantity describing the change in position, and distance traveled is the absolute value of displacement d. One ant is observed first at position […]
Can animals see UV?
Can animals see UV? What they found suggests that most mammals can, in fact, see UV light—including dogs, cats, ferrets, and reindeer. Unlike humans, these mammals have lenses that allow UV light though. Even though they lack the specialized UV-sensitive type of cone, the other three kinds of cones can combine to make up for […]
Why places near the sea have humid climate?
How do I calculate the average percentage increase?
How do I calculate the average percentage increase? To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Increase = New Number – Original Number. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × […]
What is the condition of a starved evaporator coil?
What is the condition of a starved evaporator coil? A starved evaporator coil is a condition in which not enough refrigerant has been supplied through the total coil length. Therefore, expansion of the refrigerant has not occurred through the whole coil length, resulting in poor coil operation and too-low heat exchange. When a refrigeration unit […]
Does high ionization energy mean high electronegativity?
Does high ionization energy mean high electronegativity? Ionization Energy Elements with high ionization energies have high electronegativities due to the strong pull exerted on electrons by the nucleus. Does P or CL have a higher ionization energy? The second ionization energy is always larger than the first ionization energy, because it requires even more energy […]
