Answer:
32°
Explanation:
From the question, we are told that:
The measure ∠BQS of is 80°.
In the above diagram, m∠BQN = 48°
What is the m∠NQS?
∠BQS = m∠BQN + m∠NQS
80° = 48° + m∠NQS
m∠NQS = 80° - 48°
m∠NQS = 32°
Therefore, m∠NQS = 32°
The heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.
<h3>What is heat?</h3>
Heat is the transportation of energy to or from a thermodynamic system.
By the formula of heat

Where n = moles
Delta Hrxn is molar heat
q = heat
Putting the values in the equation

Thus, the heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.

Answer:
-56
Explanation:
From the equation:
0.75(x + 20) = 2 + 0.5(x - 2)
Open brackets
0.75x + 15 = 2 + 0.5x - 1
Collect like terms
0.75x - 0.5x = 2 - 1 - 15
0.25x = - 14
Divide both sides by 0.25
x = -56
