Answer : The moles of sucrose used in the recipe are, 1.11 moles.
Explanation : Given,
Mass of sucrose = 380 g
Formula used :
Molar mass of sucrose = 342.3 g/mole
Now put all the given values in the above formula, we get:
Therefore, the moles of sucrose used in the recipe are, 1.11 moles.

Answer:
Single Replacement reaction
Explanation:
Reaction Given:
2Na + 2HCI ------> H₂ + 2NaCl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
2Na + 2HCI ------> H₂ + 2NaCl
In this reaction two reactant combine and give 2 products.
Reactant of the reaction
Na = Sodium
HCl = Hydrochloric acid
Product of the reaction
NaCl = sodium chloride
H₂ = hydrogen gas
So,
That sodium metal react with hydrochloric acid and produce salt and water gas
Type of Reaction:
This is a Single Replacement reaction, in which Sodium metal (Na) replace the Hydrogen (H) of the other compound and form Sodium Chloride salt (NaCl) and hydrogen liberate in the form of gas.
