The liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas and hydrogen gas are
When liquid disilicon hexachloride reacts with water to form solid silicon dioxide , hydrogen chloride gas and hydrogen gas , the following chemical equation is:
now , we have to balance the eqaution,
Reactants product
Si 2 1
Cl 6 1
H 2 3
O 1 2
Multiply 4 with 2 with and 6 with HCL, we get
now ,
Reactant Product
Si 2 2
Cl 6 6
H 8 8
O 4 4
Thus, we get the desire equtions.

Answer:
C) is less than 7
Explanation:
The dissociation constant, Ka of nitrous acid, HNO2 = 4.5 * 10^-4
Ammonia, NH3, is a weak base with a Kb value of 1.8x10^-5
When a weak acid like HNO2 reacts with an equivalent amount of a weak base NH3, complete neutralization does not occur. The concentrations of the species in equilibrium with each other will depend on the equilibrium constant, K, for the reaction,
Since the dissociation constant, ka of nitrous acid is higher, at equivalence point the pH of the solution will be slightly acidic with a pH that is less than 7.
Answer:
Its enviormental science because enviormental science is an interdisciplinary academic field that integrates physical.
