Answer:
This structure shows that, "<span>Water is polar, which means it has an uneven distribution of charge making it a good solvent of other polar molecules".
Explanation:
When the Electronegativity difference between two atoms joint through covalent bond is greater than 0.4 and less than 1.7, then the bond is said to be polar bond, and molecule containing polar bonds with asymmetry are said to be polar molecules. In water the Electronegativity difference between Oxygen atom and Hydrogen atom is calculated as,
E.N of Oxygen = 3.44
E.N of Hydrogen = 2.20
-------------
Difference 1.24
Hence, the bond is Polar covalent bond.
Secondly, as we know that Like dissolves Like, so water being polar in nature will interact with polar compounds. And polar compounds will tend to dissolve in water. So, water is a good solvent for polar compounds.</span>
1) Balance of mass
CxHyOz + O2 ---> CO2 + H20
0.880 g + X = 1.760g + 0.720 g
=> X = 1.760g + 0.720g - 0.880g = 1.6 g of O2
2) C in CO2:
molar mass of CO2 = 44 g/mol
=> 12 g C / 44 g CO2 * 1.760 g CO2 = 0.480 g C
3) H in H2O
molar mass of H2O = 18.0 g/mol
2 g H / 18.0 g H2O * 0.720 g H2O = 0.080 g H
4) O
4a) O in CO2: 32gO / 44 g CO2 * 1.760 g CO2 = 1.280 g O
4b) O in H2O: 16gO / 18 gH2O * 0.720 g H2O = 0.640 g O
4c) O in CxHyOz = 1.280 g + 0.64 g - 1.6 g = 0.320 g O
5) Convert grams into moles
C: 0.480 g / 12 g/mol = 0.04 mol
H: 0.08 g / 1 g/mol = 0.08 mol
O: 0.32 g / 16 g/mol = 0.02 mol
6) Divide by the smallest number
C: 0.04 / 0.02 = 2
H: 0.08 / 0.02 = 4
O: 0.02 / 0.02 = 1
7) Use those numbers as subscripts for the empirical formula:
C2 H4 O
Answer: C2H4O
Answer:
hello, the answer is polygenic:)
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. ... The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'.
Explanation:
Fractional distillation is used to separate crude oil into simpler, more useful mixtures . This method can be used because different hydrocarbons have different boiling points
Hope this help u
