We are going to apply the equation of state for ideal gasses: P*V = n*R*T where P is pressure, V is volum, n is mols of gas, T is temperature and R is a constant value of 0.082 (atm*l)/(mol*K)
We know the temperature is 45 ÂşC so in Kelvins will be = 45 + 273.16 = 318.16 K
Then in the equation:
V = n*R*T/P = 1.5 * 0.082 * 318.16 / 2.5 = 15.65 l
So volum of gas is: 15.65 liters
CUSO4 is an example of A COMPOUND.
A compound is the product formed when two or more elements chemically combine together to form a new product or products, which are quite different from the reactants. The elements in the compound are usually combined together in a specific ratio. In the question given above, CUSO4 is a compound because, copper, sulphur and oxgyen had combined together chemically to form a new compound, which is CUSO4. The ratio of combination is 1:1:4, that is, one atom of copper combine with one atom of sulphur and four atoms of oxygen to form one molecule of CUSO4.
Answer:
Six electrons are transferred in the formation of Al₂O₃.
Explanation:
Aluminium metal and Oxygen react to form Al₂O₃ as,
2 Al + 3/2 O₂ → Al₂O₃
Oxidation number of Al on left hand side is zero, while than on right hand side in Al₂O₃ is +3. Means it has lost 3 electrons per one atom and six electrons per two atoms. Also, the oxidation number of O at left hand side in O₂ is zero, while that in Al₂O₃ it is -2 per atom and -6 per 3 atoms.
So, two Al atoms have lost 6 electrons and 3 O atoms have gained six electrons.
