7.55g (3s.f.)
All the water will cool down to 0°C, which requires 0.419*6 = 2.514kJ of heat to be removed. This requires 2.514/0.333 = 7.55g of ice to melt.
An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons.
<h3>What is an Arrhenius acid?</h3>
An Arrhenius acid increases the number of ions in the water.
According to the Arrhenius theory, a substance which has hydrogen atom and can easily give hydrogen ion or proton in its aqueous solution is called as Arrhenius acid.
For example, when hydrochloric acid is dissolved in water, it forms chloride ion () and hydronium ion ().

Volume increase comes from reduced pressure
Answer:
Molecules in order of decreasing rate of effusion:
Explanation:
Mass of gas=
Mass of gas =
Mass of gas =
Mass of gas =
According Graham's law:
'The rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas'.The equation given by this law follows the equation:
So, higher the molecular mass of the gas lower will be the effusion rate and vice versa.
Increasing order of molecular masses of the given gases:
Decreasing order of effusion rate respective to gases:
Molecules in order of decreasing rate of effusion:
