they condensate
Explanation:
for the example let's use water vapor when gas particles are cooled down they slow done and then they change the state of matter in this case it turns into a liquid hope this helps
Answer:
83 g
Explanation:
Step 1: Write the balanced equation
2 Fe + 3 S ⇒ Fe₂S₃
Step 2: Calculate the moles corresponding to 95 g of Fe
The molar mass of Fe is 55.85 g/mol.
95 g × 1 mol/55.85 g = 1.7 mol
Step 3: Calculate the moles of S needed to react with 1.7 moles of Fe
The molar ratio of Fe to S is 2:3. The moles of S needed are 3/2 × 1.7 mol = 2.6 mol
Step 4: Calculate the mass corresponding to 2.6 moles of S
The molar mass of S is 32.07 g/mol.
2.6 mol × 32.07 g/mol = 83 g
The answer is flow of heat
4 hydrogen atoms must bond
