Answer : 2 represent the coefficient.
Explanation :
As we know that:
The coefficients used in the chemical equations shows that the relative amounts of each substance present and this amount can represent either the relative number of molecules or number of moles.
If there is no coefficient then one (1) is assumed.
That means,
The coefficient tell us about that how many molecules or atoms present in the chemical equation.
By the stoichiometry we have to convert moles of a reactant to moles of a product.
The given formula is:
In this formula, 2 represent the coefficient and 4 represent the subscript and C and H represents the symbol of element.
Hence, 2 represent the coefficient.
Answer:
Explanation:
Hello,
In this case, we can represent the chemical reaction as:
In such a way, since the mass of the obtained silver chloride is 93.9 mg, we can compute the chloride ions in the ground water by using the following stoichiometric procedure whereas the molar mass of chloride ions and silver chloride are 35.45 g/mol and 143.32 g/mol respectively:
Finally, for the given volume of water in liters (0.100L), we compute the required concentration:
