Answer:
1.78 mol
Explanation:
Step 1: Write the balanced equation
CaC₂ + H₂O ⇒ C₂H₂ + CaO
Step 2: Calculate the moles corresponding to 46.3 g of C₂H₂
The molar mass of C₂H₂ is 26.04 g/mol.
46.3 g × 1 mol/26.04 g = 1.78 mol
Step 3: Calculate the moles of H₂O required to form 1.78 moles of C₂H₂.
The molar ratio of H₂O to C₂H₂ is 1:1. The moles of H₂O required are 1/1 × 1.78 mol = 1.78 mol.

Answer:
liquid has more attraction between molecules. It takes energy to break these forces to change the liquid to a gas.
Explanation:
because liquid has more attraction
A heterogeneous mixture because you can still tell apart the components in the mixture. You can differentiate between the milk and the cereal.
