There are many chemicals in seawater that make it salty. Most of them get there from rivers carrying so yes
A food web is a graphic representation of all possible energy pathways through an ecosystem.
The answer is c.
There are 3 carbon atoms and six hydrogen atoms in a double-bond linear chain.
i.e.
H2C=CH-CH3
The empirical formula will be CHCl
<h3>What is the empirical formula?</h3>
The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea. As a result, both the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide have the same empirical formula. They do not, however, have the same molecular formula, which specifies how many atoms are present in each molecule of a chemical compound.
For saran
C= 24.8% ,
H= 2.0% ,
Cl = 73.1%
= 24.8/ 12 = 2.0
= 2.0/1=2.0
= 73.1/ 35 = 2.0
Now, dividing each mole by the smallest moles (hydrogen's moles), one obtains:
C= 2.0 / 2.0 = 1
H= 2.0/2.0 = 1
Cl = 2.0/ 2.0 = 1
The empirical formula will be CHCl
