Answer:
2.5 moles of KOOH are produced.
Explanation:
1)Given data:
Number of moles of KOOH produced = ?
Number of moles of LiClO = 5 mol
Solution:
Chemical equation:
2LiClO + KHSO₄ → Li₂SO₄ + Cl₂ + KOOH
now we will compare the moles of KOOH and LiClO.
LiClO : KOOH
2 : 1
5 : 1/2×5 = 2.5
2.5 moles of KOOH are produced.
Answer: <u>Volume</u>
Explanation:
Cos Milky said it. Milky smart.
This is mostly true for chemical properties. Physical properties however don't require other substances so as to check them out such as changing the state of matter, Turning water into ice does not require other substances, only water, and yet you can check the physical properties with it. Chemical properties are checked with experiments and careful observation of what happens when things are mixed.
Answer:
-26.6kJ/mol
Explanation:
The dissolution of NH₄NO₃ is:
NH₄NO₃(aq) → NH₄⁺(aq) + NO₃⁻(aq)
To solve this question we need to find the heat released in the dissolution using the equation of coffee cup calorimeter:
Q = -m*S*ΔT
<em>Where Q is heat,</em>
<em>m is the mass of solution = 1.60g + 75.0g = 76.6g</em>
<em>S is specific heat of the calorimeter (4.18J/g°C)</em>
<em>And ΔT is change in temperature (25°C - 23.34°C = 1.66°C)</em>
<em />
The heat is:
Q = -76.6g*4.18J/g°C*1.66°C
Q = -531.5J = -0.5315kJ are released
The heat released per mole = Enthalpy for the dissolution is:
<em>Moles NH₄NO₃:</em>
1.60g * (1mol / 80.043g) = 0.0200mol
Enthalpy for the dissolution:
-0.5315kJ / 0.0200mol =
<h3>-26.6kJ/mol</h3>
