Consider the reaction 2AI(OH)3 + 3H2SO4 Right arrow. X + 6Y. What are X and Y? X = AI2(SO4)3; Y = H2O X = AI2(SO4)3; Y = H2 X =

Radda [10]

Answer :

X = $Al_2(SO_4)_3$

Y = $H_2O$

Explanation :

Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The given chemical equation is:

$2Al(OH)_3+3H_2SO_4\rightarrow X+6Y$

As we know that when aluminum hydroxide react with sulfuric acid then it gives aluminum sulfate and water as product.

The balanced chemical reaction will be:

$2Al(OH)_3+3H_2SO_4\rightarrow Al_2(SO_4)_3+6H_2O$

Thus, X is $Al_2(SO_4)_3$ and Y is $H_2O$

Un buzo que nada en las profundidades despide pequeñas burbujas de aire¿Aumenta disminuye o permanece igual el tamaño de las bur

alekssr [168]

Answer:

Al ascender las burbujas van aumentando de tamaño.

Explanation:

Las burbujas que produce el buzo debajo del agua son pequeñas moléculas de dióxido de carbono gaseoso producto de la respiración del mismo.

Ahora, a medida que las burbujas suben a la superficie, la presión que sufren estas (Presión debido al agua), es menor conforme van ascendiendo debido a la ley de Boyle: A medida que la presión aumenta, el volumen va disminuyendo.

Esto significa que al ascender las burbujas van aumentando de tamaño debido a que la presión que sufren estas es menor que cuando están a mayores profundidades.

A chemist dissolves 699. mg of pure hydrobromic acid in enough water to make up 180. mL of solution. Calculate the pH of the sol

Sedaia [141]

Answer: 1.32

Explanation:

First, we must obtain the molar mass of HBr. After that, we try to obtain the concentration of the hydrobromic acid from the formula n=CV since the volume of solution and mass of acid was provided. Recall that n=m/M. If the concentration of acid is thus obtained, we make use of the fact that the concentration of H+ in the acid is equal to the molar concentration of HBr to obtain the pH. The pH is the negative logarithm of the concentration we obtained in the initial step.
