Answer:
Final volume is 3.50L
Explanation:
It is possible to find volume of a gas using combined gas law:
<em>Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state</em>
If initial state of the gas is:
1.75L of a gas is at 700K and is under 250kPa of pressure
And final state is:
298K and 53.2kPa.
Replacing:
0.625L = 0.1785*V₂
<em>3.50L = V₂</em>
Thus, <em>final volume is 3.50L</em>
The order of increasing ionic property is;
WO3 < ZrS2 < MnS2< ZnS < MnS
Ionic compounds are compounds that contain an ion pair. Typically, ionic compounds are formed between metals and nonmetals.
The degree of ionic character depends on the type of metal involved and the magnitude of charge it carries.
Typically, first row transition metals form ionic compounds. The degree of ionic character depends on the row in which the metal is found and the magnitude of charge it carries.
Hence, the order of ionic character of the compounds from most ionic to least Ionic is; WO3 < ZrS2 < MnS2< ZnS < MnS.

Answer:
9.834 moles Cf.
Explanation:
The number of moles of a substance is an easy way to represents its amount. Avogadro has determined that the total amount in 1 mol is equal to 6.02x10²³(Avgadros' number), so 1 mol has 6.02x10²³ atoms, molecules, ions, or what we are measuring. So:
1 mol of Cf -------------------- 6.02x10²³ atoms
x -------------------- 5.92x10²⁴
By a simple direct three rule:
6.02x10²³x = 5.92x10²⁴
x = 5.92x10²⁴/6.02x10²³
x = 9.834 moles Cf
