Light ray 1 strikes the smooth surface, separating air and water as shown below. A horizontal line is drawn and the part above t

he line is labeled Air and the part below the line is labeled Water. There is one slanting ray labeled 1 which falls on the line at a point and there are four rays of light labeled 2, 3, 4, and 5 which move away from same point on the line. Ray 5 is exactly vertical to the line and below the line, ray 4 is on the right of ray 5 and makes an angle of about 25 degrees with ray 5. Ray 3 is above the line and makes an angle of about 25 degrees with the line. Ray 2 is on the right of ray 1 and ray 1 and ray 2 make angles of about 25 degrees with the vertical at the point where ray 1 strikes. Which of the following rays is the part of ray 1 that is reflected from the smooth surface? Ray 2 Ray 3 Ray 4 Ray 5

Which is the most active nonmetallic element in group 16?
timama [110]
Oxygen

For metals, reactivity increases as we move through the elements in the period table from top to bottom, and left to right. In contrast, for nonmetals, reactivity increases as we move through the elements in the periodic table, as we move from bottom to the top, and right to left. 

Group 16 on the periodic table is also called the oxygen family or chalcogens. It includes the following elements from top to bottom: Oxygen, Sulfur, Selenium, Tellurium, and Polonium. Of these, only Oxygen, Sulfur, and Selenium are nonmetals. Since reactivity of nonmetals increases going up the periodic table, oxygen is therefore the most reactive nonmetal in the group. Shown in the figure below is the reactivity trend in the periodic table.

A gold cube is 170.00 mm long, 20.00 cm wide, and 0.99 m thick. If gold has a
GaryK [48]

Answer:

Explanation:

There's 2 steps: first find the volume then the mass

volume=lwh

convert 20 cm to mm: 20x10=200mm

volume=(170)(200)(0.99)

volume=33,660 mm

since the density is in cm cubed, convert 33,660 mm to cm

33,660/10=3366

density=mass/volume, rearrange to get mass=density x volume

mass=19.3 x 3366

mass=64963.8
