Question 2 The metal molybdenum becomes superconducting at temperatures below 0.90K. Calculate the temperature at which molybden

LenKa [72]

Answer:

Temperature at which molybdenum becomes superconducting is-272.25°C

Explanation:

Conductor are those hard substances which allows path of electric current through them. And super conductors are those hard substances which have resistance against the flow of electric current through them.

As given, molybdenum becomes superconducting at temperatures below 0.90 K.

Temperature in Kelvins can be converted in °C by relation:

T(°C)=273.15-T(K)

Molybdenum becomes superconducting in degrees Celsius.

T(°C)=273.15-0.90= -272.25 °C

Temperature at which molybdenum becomes superconducting is -272.25 °C

PLEASE HELP

Olenka [21]

There is no reaction because of the common ion effect(which in this case is K)if there were a reaction the products would be the same as the reactants so no reaction happens

Question 6 (3 points)

olga55 [171]

Answer:

Explanation:

Given parameters:

Molarity of KOH = 0.26M

Volume of H₂SO₄ = 19.76mL

Molarity of H₂SO₄ = 0.20M

Unknown:

Volume of KOH = ?

Solution:

This is a neutralization reaction in which an acid reacts with a base to produce salt and water:

H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

We solve from the known to the unknown in the reaction.

The known is the acid and from there we can find the number of moles of the acid to be completely neutralized:

Number of moles of acid = molarity x volume

Number of moles of acid = 19.76 x 0.20 = 3.95mol

From the balanced reaction equation:

1 mole of acid reacts with 2 moles of the bases KOH

3.95mole of acid would react with 3.95moles x 2 of the base

Number of moles of reacting base = 7.90moles

To find the volume of base;

Volume of base = $\frac{number of moles of base}{molarity}$

Volume = $\frac{7.90}{0.26}$ = 30.40mL
