Answer:
Zinc oxide is react with sulphuric acid to give zinc sulphate and water.
zinc oxide +sulphuric acid ⇒ zinc sulphate + water
Zno +H2So4 ⇒ZnSo4 + H2O
SULPHURIC ACID = H2SO4
ZINC SULPHATE =ZnO
Explanation:
The fraction of gas phase molecules is calculated by the division of final pressure to the initial pressure.
Fraction = (1)
Here, initial pressure = 1.0 atm
final pressure =
First, convert torr into atm
1 atm = 760 torr
final pressure =
=
Now, put the value of initial and final pressure in formula (1)
Fraction =
=
Thus, fraction of the gas phase molecules =
Answer:
H2O2
Explanation:
By numbering the atoms we know about that it’s Hydrogen Peroxide
Answer: There are many possibilities for atomic orbits.
Explanation: In chemistry orbits, or orbitals, are the areas that electrons move around the nucleus of an atom. Think like the solar system.
There are three levels of orbitals (p,d, and f).
That should get you started. Use p, d and d described in your book to find out how many orbitals an atom has.
