Is our eye concave?

Is our eye concave? Q: The lens of the eye is a convex lens. Therefore, a concave lens would focus the image in front of the eye, not on the retina inside the eye. No signals would be sent to the brain so vision would not be possible. What is the function of convex lens […]

What do Li C and F have in common?

What do Li C and F have in common? The elements Li, C, and F, are all in the period (row) # 2 of the periodic table, and, in consequence, those atoms have two energy levels (main quantum number), n = 1 and n = 2, around the nucleus. Is Potassium a main group element? […]

What is food temperature control?

What is food temperature control? Using temperature controls minimizes the potential for harmful bacterial growth and toxin formation in TCS food. Temperature controls either keep food entirely out of the danger zone or pass food through the danger zone as quickly as possible. What is considered a low oven temperature? Oven Temperature Conversions Cooking Instructions […]

Is friction a form of mechanical energy?

Is friction a form of mechanical energy? The mechanical energy of the system remains constant provided there is no loss of energy due to friction. The energy would transform to kinetic energy when the speed is increasing. The mechanical energy of the system increases provided there is no loss of energy due to friction. Is […]

Which metal oxides is easiest to decompose on heating?

Which metal oxides is easiest to decompose on heating? The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Mercury(II) oxide is a red solid. When it is heated, it decomposes into mercury metal and oxygen […]
