Besides water, what is the product of a Neutalization Reaction between H2SO4 and LiOH?
tigry1 [53]

Answer:

The answer to your question is d. Li₂SO₄

Explanation:

Data

H₂SO₄ reacts with LiOH

Process

This is a neutralization reaction that occurs between an acid and a base and the products will always be water and a binary or ternary salt.

In this reaction, the acid is H₂SO₄ and the base is LiOH, then the products will be water and Lithium sulfate.

Balanced chemical reaction

                                 H₂SO₄  +  LiOH  ⇒   Li₂SO₄  +  H₂O

Measurement of heat conductivity A metal panel of area A = 100 cm² and thickness Y = 0.5 cm was found to conduct heat at a rate
RSB [31]

Answer:

The average thermal conductivity of the material at this temperature range is 3*10^(-9) W/mK.

Explanation:

The heat flow through this area of the metal panel can be expressed as:

q/A=-k\frac{(T_2-T_1)}{Y}

being A the surface area, k the thermal conductivity, T2 and T1 the temperatures in each side and Y the thickness of the metal panel.

We have to rearrange the equation to clear k:

k=\frac{-(q/A)*Y}{\Delta T} = \frac{-(3 W/100 cm2)*0.5cm}{5 ^\circ K}*(\frac{1m}{100cm} )^{3} \\\\k=\frac{0.015}{5*100^{3} }W/mK= 3*10^{-9}W/mK

The average thermal conductivity of the material at this temperature range is 3*10^(-9) W/mK.
