Answer:
The answer is 375.54 g of AgBr
Explanation:
Mass (g) = Concentration (mol/L) x volume (L) x Molecular Weight of AgBr (g/mol)
Mass = 2M x 1L x 187.77 g/mol
Mass = 375.54g
Answer:
The molecules in a solid are close together and they vibrate in place. The molecules in a liquid move quickly and farther apart from eachother. The particles in a gas move freely at high speeds and slide past eachother.
Answer:
The rate of reaction rA is an intensive parameter.
Explanation:
The rate of reaction for a chemical species is typically -rA. Negative sign only shows that reactants are consumed when time is passing in the reaction.
Reaction rate will depend of several factors such as: Constant of equilibrium - K, Concentration of species - CA, Temperature - T and so on.
When we analyze the reaction rate the units are mol/Ls. It means that reaction rate will only depend of concentration and other variables. In this way, rate of reaction only is afected when we have changes in concentrations.
Concentration is an intensive parameter, it is not important if we have 100 kg or 100 L, or even 1 Kg or 1 L of total solution. Concentrations are the proportion of them and they will remain constant independent of the total mass or volume studied.
Due to the above, concentration and rate of reaction are intensive parameters and they do not depend of the total mass or volume studied.
Answer: the strongest base will be A) HX(aq)
Explanation:
The cationic part of the base is formed from the cation in the weak acidic salt solution, (say Na2CO3= HY, and H= Na) i.e H+, whereas the anionic part of the base comes from the the weak base ( say NH4OH= HX, and X= OH-)
Then the strong base formed will be HX
