Answer:
id say c though im not sure
Explanation:
Cooling towers are primarily used for heating, ventilation, and air conditioning (HVAC) and industrial purposes.
The application of acid-base chemistry is used to formulate an answer for your question.
moles NaOH = c · V = 0.2321 mmol/mL · 26.34 mL = 6.113514 mmol
moles H2SO4 = 6.113514 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 3.056757 mmol
Hence
[H2SO4]= n/V = 3.056757 mmol / 36.43 mL = 0.08391 M
The answer to this question is [H2SO4] = 0.08391 M
Answer:

The balanced equation for the reaction is
Na2B4O7*10H2O + 2 HNO3 = 2 NaNO3 + 4 H3BO3 + 5 H2O
So for each mole of Borax to neutralize, it takes 2 moles of HNO3.
Calculate number of moles of Borax
0.2619 g / 381.372 g/mol = 0.0006867 mol
Moles of HNO3 used = 0.0006867 mol * 2 = 0.0013734 mol
Molarity is defined as moles per liter so divide the number of moles used by the volume in liters. So
0.0013734 / 0.02161 = 0.06355391 mol</span>
Answer:
(ΔHrxn) = 1.273kJ/mol
Explanation:
Applying
m=78.2, c= 3.97, ∆t= 25.8-21.7
(ΔHrxn)= mc∆t
=78.2× 3.97× 4.1= 1.273kJ/mol
