Element 1 is a moderately soft silvery-gray solid. A 5 cm x 5 cm square
of it, only 1 mm thick, is twisted using two pairs of pliers. The sheet
breaks in the middle. The freshly broken edges are lighter colored than
the surface.

Element 3 is a hard silvery-gray solid. Wires are fastened to each side of
a 2 cm slab of it, and an ordinary household 9 V battery is hooked up so

- The vitamin niacin (nicotinic acid,C6H5NO2 ) can he isolated from a variety of natural sources, such as liver, yeast, milk, and whole grain. It also can be synthesized from commercially available materials. Which Source of nicotinic acid, from a nutritional view, is best for use in a multivitamin tablet?

Without taking into consideration any historical value for the crown, what is the crown worth?arrow_forwardFill in the following blanks. As the dye concentration increases, the absorbance of the light [linearly increases, linearly decreases, exponentially increases or exponentially decreases]. The dye concentration units are [molar (M), millimolar (mM) or grams per liter (g/L)] . Although most people wrongly conclude that absorbance has units nm, in fact, absorbance is unitless. This is because it results from a ratio of light through a colored sample relative to light intensity through a clear (blank) sample. The units for the slope of the graph would be [mM, 1/mM or nm] . Hint: the slope is the change in y values divided by the change in x values. The units for the y-intercept of the graph would be [nm, nM or unitless] . The value for the slope of the line that describes the absorbance data is [6.4597 or 0.0008] The value for the y-intercept of the line that describes the absorbance data is [6.4597 or 0.0008] .arrow_forward

- Please Help, Thank you.arrow_forward1. Marie Curie was a Polish scientist that specialized in chemistry and physics. She wanted to understand how X-rays worked and noticed in her studies that the element, Uranium, gave off rays that could be measured but did not know what the rays were. She assumed that the rays came from the uranium itself instead of through different molecules interacting with each other. To study the rays, she used an instrument, called an electrometer, that studied the electricity that the rays passed through the air. Through this she was able to discover that the more uranium atoms there were in a compound, the stronger the rays that came off of it. She used this discovery to test other minerals that emitted more rays than Uranium, and discovered the elements Thorium, Polonium and Radium. Through her discoveries of these elements, scientists were able to find the structure of the atom and even how the rays can be used to fight cancer. What was Marie Curie’s observation? 2.
