Answer:

2.08×10^24 atoms

Explanation:

set up a mole to atom ratio:

3.47moles 1 mole

------------------ = ----------------------------

x atoms 6.02×10^23 atoms

cross multiply:

3.47 mole × 6.02 × 10^23 = 2.08×10^24 atoms

What two pieces of evidence did van Helmont use to reach his conclusion

Sav [38]

Explanation:

He weighed silver, dissolved it in acid, and then recovered all the original silver by reacting the solution with copper. He also showed, by using iron to recover the copper, that this displacement of one metal from its salt by using a second metal was not because of transmutation, as many had held.

Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other h

aleksandrvk [35]

Answer:

Concentration = 1.32 m

Boiling point = $83.44^{0}C$

Explanation:

Let the boiling point of two solutions = T

Let the molal concentration of the two solutions= m

The relation between elevation in boiling point and molal concentration is:

$elevationinboiling point=K_{b}Xmolality$

i) For benzene

$T-80.1=2.53Xm$

$T=2.53m+80.1$ ....(1)

ii) For carbon tetrachloride

$T-76.8=5.03Xm$

$T=5.03Xm+76.8$ ...(2)

Equating the two equations:

$5.03Xm+76.8=2.53m+80.1\\m=1.32molal$

Putting value of "m" in equation "1"

$T=2.53(1.32)+80.1=83.44^{0}C$

I need to know what is oxidized and what is reduced.

pishuonlain [190]

Answer:

1. Reduction: O₂ ; Oxidation: S

2. Reduction: F ; Oxidation: Al

3. Reduction: Zn ; Oxidation: H

Explanation:

Determine the oxidation state of each element:

2 CoS → Cobalt acts with +2, S with -2

O₂ is at ground state. In ground state the elements has oxidation state of 0.

In CoO, the oxygen acts with -2

The oxidation state has decreased; oxygen was reduced.

In SO₂, sulfur acts with +4; oxidation state has increased, so S has been oxidized.

2. Both reactants are at ground state.

In AlF₃ Al has oxidation state of +3 and F, -1

Al increased the oxidation state → oxidation

F decreased the oxidation state → reduction

3. Hydrogen has 0 as oxidation state. In water, H has +1

It was increased → oxidation

Zn acts with +2, in the zinc oxide. As we have elemental Zn, the oxidation state is 0; it has decreased → reduction
