Chemical reaction and equation
Answer:
1.5*10^(-2)
Explanation:
0.015 is the answer for (3*10^2)*(5*10^-5)
(3*100)*(5*0.00001)
300*0.00005 = 0.015
1.5*0.001 = 0.015
Bromine.
Oxygen, selenium, and sulfur are all in group 16 and have 6 valence electrons. Bromine is in group 17 and has 7 valence electrons. The closer to 8 (a full, stable octet) you get, the less likely the element is to react.
To answer this item, we need to utilize the appropriate the conversion factors and the dimensional analysis.
Our basis for solving is 1 kilometers. It is known that each kilometer is composed of 1000 meters.
(1 km) x (1000 m/1 km) = 1000 m
Next, we need to determine the number of centimeters. The conversion factor that can be used is 1 meter = 100 centimeters
(1000 m) x (100 cm/ 1 m) = 100,000 cm
Lastly, we use the given conversion factor to convert the centimeters to inches.
(100,000 cm) x (1 inch / 2.54 cm)
= 39,370.08 in
<em>ANSWER: Each kilometer is composed of 39,370.08 inches</em>
<em>Answer</em><em>:</em><em>2</em><em>7</em><em>%</em><em> </em><em>According</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>cylinder</em><em>.</em>
