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:
H
Explanation:
Hydrogen is a nonmetal love:)
We calculate the entropy of an ideal gas follows:
<span>For an isothermal compression, change in internal energy is equal to zero.</span>
<span>Thus, the heat added to the gas is equal to the work done on the gas which is given as 1750 J.</span>
<span>Entropy would be 1750/301 = 5.81 J/K </span>
the properties of liquids usally wet, wet shows expiation on heating and contracting on cooling
What’s the question cuz I’m confused lol
