<span>The answer is melting and freezing point. At the melting point the solid and liquid stage occur in equilibrium. The melting point of a material hinge on pressure and is typically quantified at standard pressure. When measured as the temperature of the opposite alteration from liquid to solid, it is denoted as the freezing point.</span>
Answer:
Molecular formula = C20H30
Explanation:
NB 440mg = 0.44g, 135mg= 0.135g
From the question, moles of CO2= 0.44/44= 0.01mol
Since 1 mol of CO2 contains 1mol of C, it implies mol of C = 0.01
Also from the question, moles of H2O = 0.135/18= 0.0075mole
Since 1 mol of H2O contains 2mol of H, it implies mol of H = 0.0075×2= 0.015 mol of H
To get the empirical formula, divide by smallest number of mole
Mol of C = 0.01/0.01=1
Mol of H = 0.015/0.01= 1.5
Multiply both by 2 to obtain a whole number
Mol of C =1×2 = 2
Mol of H= 1.5×2 = 3
Empirical formula= C2H3
[C2H3] not = 270
[ (2×12) + 3]n = 270
27n = 270
n=10
Molecular formula= [C2H3]10= C20H30
Answer:
Condensation is the change from vapor to condensation (solid or liquid) and Evaporation is the change of liquid to gas
How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
