43g id say. Due to conservation of mass that is the only one that makes even slight sense. If you had more air react then the nail would heavier
Volume = 3 cm × 3cm × 3cm
= 27 cm ³
Mass = 213 g
Density =
= <span>
</span>
<span> = 7.89 g / cm³
Thus answer is D.</span>
You may feel cold when you touch certain kinds of matter because some matter gives off cold air. I’m NOT SURE
You should use Avogadro’s number for the conversion, because Avogadro’s Law states that there are 6.02 x 10^23 atoms per 1 mol of that substance.
Answer:
in the fraction distillation method, two liquids such as benzene and toluene are produced from the mixture of benzene and toluene.
Explanation:
Fractional distillation is a technique used in the industries for the separation of two or more liquids from one another. In this process liquid is heated, those liquid has lower boiling point will change into vapor form and collect in the upper chamber of fractional distillation while the liquid having higher boiling point also evaporates after sometime and keep it in another chamber. In the mixture of benzene and toluene, the boiling point of benzene is lower so it evaporates earlier than toluene.
