Arrhenius was seeking to understand the causes of ice ages.
He was the first to use basic principles of physical chemistry to calculate estimates of the extent to which increases in atmosphere carbon dioxide increases Earth's surface temperature through the Arrhenius effect. Arrhenius's paper was the first to quantify the contribution of carbon dioxide to the greenhouse effect and to speculate whether variations in the atmospheric concentration of carbon dioxide have contributed to long-term variations in climate.
Answer:
a structural formula
Explanation:
A structural formula simply shows the arrangement of atoms on a compound or molecule.
They are mostly used in representing hydrocarbons.
Through a structural formula we can give name to a compound.
For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.
The bond relationship connecting the species are also shown in this designation.
Answer:
12 mi/h
Explanation:
Step 1: Given data
Step 2: Convert "d" to miles
We will use the conversion factor 1 mi = 1.60934 km.
6 km × 1 mi/1.60934 km = 3.7 mi
Step 3: Convert "t" to hours
We will use the conversion factor 1 h = 60 min.
19 min × 1 h/60 min = 0.32 h
Step 4: Calculate the average speed of the runner (s)
The speed is equal to the quotient between the total distance and the time elapsed.
s = d/t
s = 3.7 mi/0.32 h = 12 mi/h
C6H6(l) + 6 Cl2(g) = C6Cl6(s) + 6 HCl(g)
There are 76 atoms in total
