Ionic compounds will produce ions
The amount of atomic particles released by a radioactive material in a specific time is determined by the strong and the weak nuclear force. It is these forces that holds the nucleus of the atom and the force that needs to be overcome with to allow radioactive decay.
So they can avoid planes meeting up at the same time
Substituting a hydrogen atom with a halogen in a hydrocarbon:
- the single bond remains single. A is wrong.
- the bond with Hydrogen is as strong as with a Halogen. C is wrong
- a hydrocarbon is saturated if there is no double bond. We do not know that so D is wrong.
- carbon will always have four valence electrons. E is wrong.
By elimination, the correct answer is B. The boiling point of the new compound increases.
Answer:
V = 22.86 L
Explanation:
Given data:
Mass of nitrogen dioxide = 45000 mg
Pressure = 1 atm
Temperature = 273 k
Volume = ?
Solution:
First of all we will convert the mass into moles.
<em>Number of moles = mass/ molar mass</em>
Number of moles <em>= </em>45 g/ 46 g/mol
Number of moles = 1.02 mol
Now we will determine the volume at STP.
PV = nRT
V = nRT/P
V = 1.02 mol × 0.0821 atm. mol⁻¹. k⁻¹. L× 273 k / 1 atm
V = 22.86 atm. L /1 atm
V = 22.86 L
