The distance between two bonded atoms (the bond length), is usually in units of picometers, where 1.00 m = 1.00 x 1012 pm (or 1.00 pm = 1.00 x 10-12 m). What is the distance between two carbon atoms, in units of miles, if the bond length is 121 pm?

7.52 × 10⁻¹⁴ mi

Explanation:

Step 1: Given data

Bond length between two carbon atoms (l): 121 pm

Step 2: Convert "l" to meters

We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.

121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m

Step 3: Convert "l" to miles

We will use the conversion factor 1.00 mi = 1609.34 m.

1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
