Answer: 1.98 g
Explanation:
To calculate the moles :
The balanced given equation is:
According to stoichiometry :
4 moles of will produce = 2 moles of
Thus 0.22 moles of will produce=
of
Mass of
Thus 1.98 g of water is produced along with 5.0 L of at STP
Answer:
The diameter of the oil molecule is .
Explanation:
Mass of the oil drop =
Density of the oil drop =
Volume of the oil drop: v
Thickness of the oil drop is 1 molecule thick.So, let the thickness of the drop or diameter of the molecule be x.
Radius of the oil drop on the water surface,r = 41.8 cm = 0.418 m
1 cm = 0.01 m
Surface of the sphere is given as: a =
Volume of the oil drop = v = Area × thickness
The thickness of the oil drop is and so is the diameter of the molecule.
, a crystal structure with a short symmetrical hydrogen bond.
Classical models of the chemical bond. By classical, we mean models that do not take into account the quantum behaviour of small particles, notably the electron. These models generally assume that electrons and ions behave as point charges which attract and repel according to the laws of electrostatics.
Sodium dihydrogen phosphate is a derivative composed of glycerol derivatives formed by reacting mono and diglycerides that are derived from edible sources with phosphorus pentoxide followed by neutralization with sodium carbonate.
