Answer:
Newton's Second Law
Explanation:
Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
(I'm going to assume this is an option, but please let me know if it's not!)
Answer:
C ) 1.70 g/L
Explanation:
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Also,
Moles = mass (m) / Molar mass (M)
Density (d) = Mass (m) / Volume (V)
So, the ideal gas equation can be written as:
PM=dRt
At STP,
Pressure = 1 atm
Temperature = 273.15 K
Molar mass of fluorine gas = 38 g/mol
Applying the equation as:
1 atm × 38 g/mol = d × 0.0821 L.atm/K.mol × 273.15 K
<u>⇒d = 1.70 g/L</u>
Answer:
149.6 grams
Explanation:
Mass in gram = molar mass * number of moles
Massof CO2 in gram = 44*3.4=149.6 grams
Explanation:
Molecules which are either polar in nature or contain a polar covalent bond are able to dissolve in water. This is because like dissolves like.
For example, 
is a polar covalent compound and when it is dissolved in water then its reaction is as follows.
This shows that a chemical reaction will take place when is dissolved in water.
Also, HI is a polar covalent compound and it will readily dissolve in water as hydrogen iodide (HI) is a polar covalent molecule.
On the other hand, 
, 
, and 
does not dissolve in water as all of these are non-polar covalent compounds.
Thus, we can conclude that the gas most likely to dissolve in water as a result of chemical reaction is and the gas most likely to dissolve in water because of strong intermolecular interactions is HI.
