Answer:
The full stop (Commonwealth English), period (North American English) or full point . is a punctuation mark. It is used for several purposes, most often to mark the end of a declarative sentence (as opposed to a question or exclamation); this sentence-terminal use, alone, defines the strictest sense of full stop.

Initial temperature = -189.4 °C
<h3>Further explanation</h3>
Given
the volume of a gas is changed from 3.6 L to 15.5 L
final temperature = 87 °C = 87+ 273 = 360 K
Required
initial temperature
Solution
Charles's Law
<em>When the gas pressure is kept constant, the gas volume is proportional to the temperature </em>
Answer:
7.04 g
Explanation:
Let's consider the reaction in the last step of the Ostwald process.
3 NO₂(g) + H₂O(l) → 2 HNO₃(aq) + NO(g)
The molar mass of HNO₃ is 63.01 g/mol. The moles corresponding to 6.40 g are:
6.40 g × (1 mol/63.01 g) = 0.102 mol
The molar ratio of NO₂ to HNO₃ is 3:2. The reacting moles of NO₂ are:
0.102 mol HNO₃ × (3 mol NO₂/2 mol HNO₃) = 0.153 mol NO₂
The molar mass of NO₂ is 46.01 g/mol. The mass corresponding to 0.153 moles is:
0.153 mol × (46.01 g/mol) = 7.04 g
Explanation:
5N right because -15N for left plus +20N for right = +5N
