Assuming you meant a 0.7 mole sample of a gas, we can approximate this by assuming that the gas is acting ideally, and use the ideal gas law PV=nRT. Using the following values:
P = 1.2 Atm
V = 0.170 L
n = 0.7 mol
R = 0.08206 L-atm/mol-K
We can rewrite the equation as: PV/nR = T
Plug in our values:
(1.2 atm)(0.170 L)/(0.08206*0.7 moles) = approximately 3.55 Kelvin = T
Answer:
Mole fraction of water is 0.8.
Explanation:
Mole fraction is defined as ratio of moles of single component to the sum of moles of all components present in the solution.
Moles of ethylene glycol = 
Moles of water = 
Mole fraction of ethylene glycol = 
Mole fraction of water = 
because the gas particles are forced closer together.
bromine
Explanation:
halogens are a group of elemnts simlar to eachother
flourine, chlorine, and bromine
Answer:
B
Explanation:
Applying law of electrostatic which states that like charges repel each other and unlike charges attract each other
N and S are unlike charges that turn and make the former repulsive force (due to two like charges N and N)to <em>reduce</em> and attractive force between N and S to <em>increa</em><em>se</em>
