An object floats in a liquid if that object is less dense than that liquid, therefore your answer is
A.
Hope this helped :)
Equilibrium concentration of SO3=1.7M
Equilibrium concentration of SO2=0.070 M
Equilibrium concentration of NO2=1.3 M
Equilibrium constant is given as=10.8
The equilibrium reaction is given as:
SO2(g)+NI2(g)⇌NO(g) +SO3(g)
Keq= ([NO][SO3])/([SO2][NO2])
To calculate concentration of NO rearranging the above equation will give:
NO=Keq*[SO2][NO2]/[SO3]
NO=(10.8*0.070*1.3)/1.7
= 0.578M
So concentration of NO will be 0.578M
Answer : The temperature of neon gas will be, 221.0 K
Explanation :
To calculate the temperature of neon gas we are using ideal gas equation.
where,
P = pressure of neon gas = 96.7 kPa = 0.955 atm
Conversion used : (1 atm = 101.3 kPa)
V = volume of neon gas = 9.50 L
T = temperature of neon gas = ?
R = gas constant = 0.0821 L.atm/mole.K
w = mass of neon gas = 10.00 g
M = molar mass of neon gas = 20 g/mole
Now put all the given values in the ideal gas equation, we get:
Therefore, the temperature of neon gas will be, 221.0 K
Answer:
When creating a business many things come into mind. Some thoughts that need to be considered are demand (do consumers want this product), supply (can the materials needed to make this product be easy accessible), and prices (will my product be affordable while maintaining a profit). :)
