Answer:
Explanation:
CH4 + 2O2 --> CO2 + 2H2O
1mol generates 2 moles of H2O
Therefore 6 Moles produce 12 moles of H2O
Answer:
Cs and I
Explanation:
Salts are formed when an ionic bond is formed between two elements in the compound. Let us recall that the kind of bond formed between any two elements depends on the magnitude of electronegativity difference between the two elements.
Among the options listed, the highest degree of electronegativity difference occurs for the bond between Cs and I. This implies that this bond is ionic and the combination of the two elements will lead to salt formation.
Answer : The correct option is, (A) 0.109 M 
Solution : Given,
Mass of = 17 g
volume of solution = 974 ml
Molar mass of = 159.609 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
w = mass of (solute)
M = molar mass of
= volume of solution in liter
Now put all the given values in the above formula, we get the molarity of solution.
Therefore, the molarity of the solution is, 0.109 M
