Answer:
C2H5NO
Explanation:
constituent elements N O C H
Mass composition 0.420 0.480 0.540 0.135
mole ratio 0.42/14 0.48/16 0.54/12 0.135/1
= 0.03 0.03 0.045 0.135
dividing by the smallest 0.03/0.03 0.03/0.03 0.045/0.03 0.135/0.03
ratio = 1 1 1.5 4.5
= 1 1 2 5
EMPERICAL FORMULA = C2H5NO
Answer:Sodium Bicarbonate
Explanation:Crack is manufactured by using Sodium Bicarbonate (NaHCO3) to remove hydrochlorides to create a crystalline form of cocaine that can be smoked.
The answer is 163.333993748 grams
Given:
2.5 mol O2
Required:
Grams of water
Solution:
2H2 + O2 -> 2H2O
Moles of H2O = (2.5 mol O2)(2
moles H2O/1 mole O2) = 5 moles H2O
Molar mass of H2O = 18.02 g/mol
Mass of H2O = (5 moles H2O)( 18.02
g/mol)
Mass of H2O =90.1g H2O
Answer:
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. For a smooth surface, reflected light rays travel in the same direction.
