Answer:
The molecules in 2,14 mol CO is 1, 29 x 10 ^ 24. See the explanation below, please.
Explanation:
We use the number of Avogadro:
1 mol----- 6, 02 x10 ^23 molecules
2,14 mol---- x =(2,14 mol x6, 02 x10 ^23 molecules )/ 1mol
x=1, 29 x 10 ^ 24 molecules
25 miles/gallon should be the answer
hope this helped out hon :)
Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.
<h3>What is a separation technique?</h3>
A separation technique can be defined as a technique that is used to separate (convert) two or more mixture and solution of chemical substances into distinct products such as solutes, chemical compounds or elements.
<h3>What is a chemical element?</h3>
A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.
Generally, some examples of a chemical element include the following:
In Chemistry, sodium hydroxide, caustic soda, or lye all refer to the same chemical compound which is represented by this chemical symbol, NaOH.
According to the narration, Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.

Answer:
A protein is more stable in its native form, because apart of weak interactions between R groups, it also presents other stronger interactions, as those including covalent bonds
Explanation:
For example, covalent bonds between sulfur atoms when disulfide bridges are built. These links are very difficult to break and maintains the protein shape. Disulfide bonds are a few but they use to incide in the structure of native proteins
