Answer:
Heavy water is a compound that is made up of oxygen and deuterium, a heavier isotope of hydrogen which is denoted by ‘ 2 H’ or ‘D’. Heavy water is also called deuterium oxide and is denoted by the chemical formula D 2 O.
Density: 1.107 g/mL
Dipole moment: 1.87 D
Heavy Water (Deuterium Oxide): D2O
Molecular Mass: 20.02 grams/mole
Explanation:
Answer: the correct answer is (A).
Explanation:
Structural formula not only tells us about the number and types of atoms in a molecule but also tells us about the bonded positions of all the atoms in a molecule of that particular compound.
Molecular structure only tells us about the numbers of atoms and types of atoms present in a molecule of that particular compound.
For example: Molecular formula of propanone and propanal are same that is
but structural formula is different that
for propane and
for propanal. Here structural formula is showing that how the atoms in propanone and propanal are bonded together.
Hence, the correct answer is option (A).
Hello!
The ball took up 2,9L
To solve this problem, we should apply the
ideal gas law and clear for n (the number of moles), as this value doesn't change when Devin takes the ball to the garage:

Now, we should clear this equation to find V2, as this is the value we are looking for:

≈2,9L
Have a nice day!
I believe your answer will be 40
