It takes exactly 500 seconds for the sun's radiation to reach the earth or about 8 minutes (8.333333333333... to be exact). Just divide 150 million km by 300,000 km/s. Hope this helps
<span>The strong bonds give graphite high boiling and melting points, while the weak bonds make graphite soft and flexible.</span>
Cylinder A - Adding 25 grams raised the water level by roughly 3.2 mL
Cylinder B - Adding 25 grams raised the water level by roughly 2.8 mL
Cylinder C - Adding 25 grams raised the water level by roughly 3.5 mL
Calculate grams/mL (density)
A. 25 g/3.2 mL = 7.8125 g/mL = Iron
B. 25 g/2.8 mL = 8.9286 g/mL = Nickel
C. 25 g/3.5 mL = 7.1429 g/mL = Zinc
Hope I helped!
Many molecules contain bonds that fall between the extremes of ionic and covalent bonds. ... (The covalent bonds between the hydrogen and chlorine atoms in HCl are 130 times as strong.) The force of attraction between HCl molecules is so small that hydrogen chloride boils at -85.0oC. (Found it online, hope it helps though)
