The balanced equation for the above reaction is as follows;
2H₂ + O₂ --> 2H₂O
stoichiometry of O₂ to H₂O is 1:2
number of O₂ moles reacted - 40.3 g / 32 g/mol = 1.26 mol
according to molar ratio
number of water moles produced = 2 x number of O₂ moles reacted
number of water moles formed - 1.26 x 2 = 2.52 mol
mass of water produced = 2.52 mol x 18 g/mol = 45.4 g
45.4 g of water produced
Answer:
a. chain length and degree of saturation.
Explanation:
Fatty acids can be classified according to the length of their chain, for example, in short (if it has less than 8 carbons), medium (between 8-12 carbons), long (between 12-18 carbons) and very long (if it has less than 18 carbons); they are also classified according to their degree of unsaturation, in saturated, monounsaturated and polyunsaturated; and according to the isomerism in cis and trans fatty acids.
the answer is the elements Helium, Neon, Fluorine, and Oxygen are logically the least metallic.
Based on science 4) 1) 0.25M
2) 0.66M
3) 1.5M
4) 4.0M ––> Therefore, this is the most concentrated
5) 30g NaOH(1 mol NaOH / 40gNaOH) = 0.75 mol NaOH / 0.500L = 1.5M NaOH (3)
6) 1) 1.0 mol / L(1 L) = 1 mol H2SO4
2) 1 mol / L (2 L) = 2 mol H2SO4
3) 0.50 mol / L ( 1.0L) = 0.50 mol H2SO4 ––>
7) 0.200 mol / L (1 L)(74.6g / mol) = 14.92g (2)
8) 0.25 mol / 0.250 L = 1 mol / L = 1M (1)
This is the answer : 1m
