Answer: Option (4) is the correct answer.
Explanation:
When sulfuric acid reacts with calcium hydroxide then it results in the formation of calcium sulfate and water.
The chemical reaction for the same will be as follows.
Thus, we can conclude that 
salt is produced when sulfuric acid and calcium hydroxide react completely.
Answer:
It is heterogeneous as it is made up of visibly different substances or phases.
The ridge of mid ocean b is the answer hope this helps
Answer : La carga nuclear efectiva (Zef) es la carga positiva neta experimentada por un electrón en un átomo polielectrónico. El término "efectiva" se usa porque el efecto pantalla de los electrones más cercanos al núcleo evita que los electrones en orbitales superiores experimenten la carga nuclear completa
Explanation:
Answer:
Composition of the mixture:
%
%
Composition of the vapor mixture:
%
%
Explanation:
If the ideal solution model is assumed, and the vapor phase is modeled as an ideal gas, the vapor pressure of a binary mixture with 
and 
molar fractions can be calculated as:
Where 
and 
are the vapor pressures of the pure compounds. A substance boils when its vapor pressure is equal to the pressure under it is; so it boils when 
. When the pressure is 0.60 atm, the vapor pressure has to be the same if the mixture is boiling, so:
With the same assumptions, the vapor mixture may obey to the equation:
, where P is the total pressure and y is the fraction in the vapor phase, so:
%
The fractions of B can be calculated according to the fact that the sum of the molar fractions is equal to 1.
