i don't understood your question ⁉️
and what do u mean by my color is sickle
Answer:
high boiling aromatics
with the same ground glass joint.
Explanation:
The black connectors are more resistant to the reactant than the white connectors. This implies that the black connectors should be used when high boiling aromatics are present, Else, the tan connections can be used.
Thus, the connectors can combine different pieces of glassware or components <u>with the same ground glass joint.</u>

Answer:
15.9 g
Explanation:
(Take the atomic mass of C=12.0, H=1.0, O=16.0)
no. of moles = mass / molar mass
no. of moles of octane used = 11.2 / (12.0x8 + 1x18)
= 0.0982456 mol
Since oxygen is in excess and octane is the limiting reagent, the no. of moles of H2O depends on the no. of moles of octane used.
From the balanced equation, the mole ratio of octane : water = 2:18 = 1: 9,
so this means, one mole of octane produced 9 moles of water.
Using this ratio, we can deduce that (y is the no. of moles of water produced):
y = 0.0982456x9
y= 0.88421 mol
Since mass = no. of moles x molar mass,
mass of water produced = 0.88421 x (1.0x2+16.0)
=15.9 g
Rutherford carried out some experiments which lead to a change in ideas around the atom. his new model described the atom as a tiny dense, positively charged core called nucleus surrounded by lighter negatively charged electrons
