Answer:
Explanation:
Empirical formula of ionic compound formed by two ions and
is
(for
) of AB (for x = y)
The above empirical formula is in accordance with charge neutrality principle
Here each cation ( and
) can form two ionic compounds by combining with two given anions (
and
).
So the four ionic compounds are:
Answer:
The specific heat capacity of the unknown metal is 0.223
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
Replacing:
418.6 J= c* 75 g* 25 C
Solving:
c= 0.223
