Answer:
Total mass of leaked fluorine in six months= 0.405 kg
Explanation:
From the given,
Leaked mass of freon = 35.12 gm
Molecular mass of freon = 
Total weeks per month = 4
Fluorine released into the air in total weeks = 
3 molecules of fluorine is present in the freon
Total mass of fluorine leaked in six months = 
Ion channels allow things to cross the membrane
The most common pairing would be sodium forming an ion after transfering an electron to chlorine
Answer:
The diagram is incorrect because there is only a single type of particle at the center of the atom.
Explanation:
The small circle at the centre of the sphere which contains six light gray spheres and six dark gray spheres represents the nucleus of the atom which is found at the centre of the atom.
The nucleus contains only one type of particle which is the proton. Hence the representation of two particles at the centre of the circle makes the model incorrect.
Answer:
The new volume of the gas remains the same. That is new volume of gas is 1.33 litres
Explanation:
This is because gases do not have a definite shape. They therefore take the shape of their containing vessels and hence their volumes are determined by the volume of the container.
For the question above even if some of the gas escapes, as long as there is gas present in the container, its volume remains the same, that is occupies the same space in the container
