Answer:
your answer will be C
Explanation:
remember low souunds carry sound waves farther than high pithed sounds.
Answer: 0.002 M
Explanation:
The balanced chemical equation for ionization of
in water is:

According to stoichiometry :
1 mole of
ionizes to give =2 mole of
ions
0.001 mole of
ionizes to give =
mole of
ions
Thus
of a solution of 0.001 M aqueous sulfuric acid is 0.002 M
A redox reaction --> a reaction whereby oxidation & reduction occurs
Reduction:
Charge of Cl2 = 0
Charge of Cl- in NaCl = -1
Hence, since charge of Cl2 decreased from 0 in Cl2 to -1 in NaCl, reduction occured.
Oxidation:
Charge of Na = 0
Charge of Na+ in NaCl = +1
Hence, since charge of Na increased from 0 in Na to +1 in NaCl, oxidation occured.
Since both oxidation & reduction occured in the reaction, it is a redox reaction.
Answer:
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
