A. Is fruit ripening dependent on the type of light the fruit is exposed to, because B, C, and D are all based on opinion and different mind sets whereas A can be found out through experimentation.
Answer:
Distillation
Explanation:
Distillation is the process of separating the components of a liquid by using the method of selective boiling and condensation.
Since the components of the liquid have different boiling points, they would evaporate at different temperatures, thus causing the separation to occur.
So, distillation can be used to separate a mixture of milk and water.
Answer:
X 154
Check solution in explanation
Explanation:
Average atomic mass = ( mass 1× abudance) + ( mass 2× abudance)+ ( mass 3× abudance) / 100
(149×13.8)+(152×44.9) +(154×41.3)/100
2056.2 + 6824.8 + 6360.2/100
=152.412
2 H₂O (l) → 2 H₂ (g) + O₂ (g)
Molar mass water = 1.01 x 2 + 16.00 = 18.02 g/mol
Number of mol water decomposed = 28.7 g H₂O x [1 mol / 18.02g] = 1.59 mol H₂O
<span>From the balanced equation 2 mol H₂O decomposes to 2 mol H₂ and 1 mol O₂ </span>
so the mole ratio water : oxygen = 2 : 1
and number of mol O₂ produced = ½ x 1.59 = 0.796 mol O₂
The ideal gas law is PV = nRT
so V = nRT/P
P = 0.986 atm
V = ?
n = 0.796
R = 0.0821 L atm K⁻¹ mol⁻¹
T = 294K
V = 0.796 x 0.0821 x 294 / 0.986
V = 19.5 L
<span>So 19.5 L O₂ gas are produced
