Answer is option C. The gas is placed under increased pressure.
Explanation:
According to Gas laws,
If the temperature to gas increases then the molecules of gas gets additional energy and moves with more spped than earlier which gives more more colliding to the walls of container. This increases pressure.
The volume and gas in a container are directly proportional to each other.
This means if the volume gets decreased then the collision of gas molecules to the walls increases which results increase in pressure.
Therefore, volume is inversely proportional to pressure.
Electronegativity.
Electronegativity can be defined as the measure of affinity of the element towards electrons . Higher the affinity towards electrons higher the electronegativity.
Eg : Fluorine has a high electronegativity. This is because it has 7 valence electrons, to gain a noble gas configuration / complete outer shell it needs to gain one electron. Hence the positive nuclear charge of the nucleus will attract an electron so it can become a complete outer shell , therefore F is very reactive.
Higher the attraction of the nucleus to electrons , higher its affinity therefore higher electronegativity.
Answer:
The chlorine gas and potassium bromide solution react to form liquid bromine and potassium chloride solution.
Explanation:
Chemical equation:
Cl₂(g) + KBr (aq) → KCl (aq) + Br₂(l)
Balanced chemical equation:
Cl₂(g) + 2KBr (aq) → 2KCl (aq) + Br₂(l)
This equation showed that the chlorine gas and potassium bromide solution react to form liquid bromine and potassium chloride solution.
Chlorine is more reactive than bromine it displace the bromine from potassium and form potassium chloride solution.
The given equation is balanced and completely hold the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
