2 N2 (g) + O2 (g) ---> 2 N2O (g) H= +163.2 kj/mol

Chemistry

VLD [36.1K]2 years ago
5 0

Answer:

46.3 kJ

Explanation:

Step 1: Write the thermochemical equation

2 N₂(g) + O₂(g) ⇒ 2 N₂O(g)  ΔH= +163.2 kJ/mol

Step 2: Calculate the moles corresponding to 25.0 g of N₂O

The molar mass of N₂O is 44.01 g/mol.

25.0 g × (1 mol/44.01 g) = 0.568 mol

Step 3: Calculate the heat released when 0.568 moles of N₂O are produced

According to the thermochemical equation, 163.2 kJ are required per 2 moles of N₂O.

0.568 mol × (163.2 kJ/2 mol) = 46.3 kJ

Which prefix is needed when naming SO3?
Karolina [17]
The formula shows that molecule is made of one sulfur atom and three oxygen atoms. This means that the prefix used should be 'tri'. This means three and the substance would be called sulfur trioxide. A molecule with two oxygen atoms would be named sulfur dioxide. The nomenclature of chemicals often uses prefixes so the name itself can give a picture of what it is made of.

AS Of Jahuary 2009, the USA has produced 60,000 metric tons of nuclear waste in 60 years of operating 104
Dmitry [639]

Waste produced by each plant : 0.8 tons per month

<h3>Further explanation</h3>

Given

60,000 metric tons of nuclear waste in 60 years of operating 104

nuclear power plants.

Required

Waste produced

Solution

60,000 metric tons=60 years, so in one year :

\tt \dfrac{60,000}{60}=1000~metric~tons

1000 metric tons/year = 83.33 metric tons/month

For each plant :

\tt \dfrac{83.33}{104}=0.8
