Answer:
Multiply the element's atomic mass by the number of atoms of that element in the compound. This will give you the relative amount that each element contributes to the compound. For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.
Answer:
1.054 x 10²⁴ molecules
Explanation:
In order to convert moles <em>of any given substance</em> into a number of molecules, we need to use <em>Avogadro's number</em>, which states the number of molecules -or atoms, in the case of elements- present in one mol:
- In one mol there are 6.023x10²³ molecules.
We now <u>convert 1.75 moles into molecules</u>:
- 1.75 mol * 6.023x10²³ molecules/mol = 1.05x10²⁴ molecules
C. 14 protons and 14 electrons
There are 32 valence electrons for the Lewis structure for ClO4
Answer:
The structures are shown in the figure.
Explanation:
The primary hydrogens are those which are attached to primary carbon.
Primary carbons are the carbons which are attached to only one carbon.
Primary carbons is bonded to three hydrogens.
In order to draw such structure we will draw structures which will have carbon with three hydrogens or no hydrogens (quaternary)
The structures are shown in the figure with clear marking.
