Answer:
C6H10Cl2
Explanation:
Convert mass % to mass
100g of the compound contains from each elements: 46,3g Cl; 47,05g C and 6,63g H
Molar mass
Cl = 35.5 g/mol
C = 12 g/mol
H = 1 g/mol
Find the number of moles:
Chlorine: 46.4g /35.5g/mol = 1,3 moles
Carbon: 47,05g/12 g/mol = 3,92 moles
hydrogen: 6,63g/1g/mol = 6,63 moles
Molar fraction:
Cl = 1,30/ 1,30 = 1
C = 3,92/ 1,30 = 3,01
H = 6,63/ 1.30 = 5,01
C3H5Cl = 76,5 g/ mol x 2 = 153 g/ mol
So multiply the molecular formula by two = C6H10Cl2
Answer: Cell components encompass phagocytic cells, epithelial and endothelial cells, natural killer cells, innate lymphoid cells, and platelets.
Explanation: Although it is ancient, the innate immune system is highly complex and consists of barriers to infection (epithelia of skin, gastrointestinal, respiratory, genitourinary tracts), antimicrobial peptides and proteins, humoral components (i.e. complement and opsonins) and cellular components (i.e. neutrophils, monocytes).
A. which I'm guessing are carbon and hydrogen
