Answer:
(a) C5H8O2
(b) C2H2Cl2
(c) CH2
(d) CH
Explanation:
We need to find the proportion of the atoms in whole numbers. Given the percentages we can calculate the number of moles and find their proportions.
Assume 100 g and given the atomic weights the moles are calculated.
(a) C = 59.9/ 12.01 = 4.98 ≈ 5.00
H = 8.06/1.007 = 8.00
O = 32/15.999 = 2.00
C5H8O2
(b) C= 24.8/12.01 = 2.06≈ 2.00
H = 2.0/1.007 = 1.99 ≈ 2.00
Cl = 73.1/ 35.453 = 2.06 ≈ 2.00
C2H2Cl2
(c) C = 86/12.01 = 7.16
H= 14/1.007 = 13.90
7.16:13.90 ≈ 1:2
CH2
(d) C = 92.30/12.01 = 7.68
H = 7.7 / 1.007 = 7.65
7.68:7.65 ≈ 1:1
CH
Answer: hypodermis
Explanation:
The very bottom layer of the skin is the hypodermis. It contains the fat cells, or adipose tissue, that insulate the body and help it conserve heat.
God bless you!!
NH₃(aq) + HNO₃(aq) = NH₄NO₃(aq)
Ammonia is a weak base. The reaction of ammonia and nitric acid is a neutralization reaction.
NH₃ + H₂O = NH₄⁺ + OH⁻
HNO₃ + H₂O = H₃O⁺ + NO₃⁻
OH⁻ + H₃O⁺ = 2H₂O (neutralization)
Answer:
When the thermometer was placed next to the skin, it should be higher because of the heat your body gives off, and the jacket trapping the heat in, when you put it in the closet it will be cooler due to not having a heat source.
