Which scientist developed the 1st model of the atom that showed the structure of the inside of an atom?

Ag+(aq) + e- → Ag(s) E° = +0.800 V AgBr(s) + e- → Ag(s) + Br-(aq) E° = +0.071 V Br2(l) + 2 e- → 2 Br-(aq) E° = +1.066 V Use some

Gekata [30.6K]

Answer:

$k_{sp}=4.7 \times 10^{-13}.$

Explanation:

Now equation of tqo halves are:

Oxidation : $Ag(s)-->Ag^+(aq)+e^-$

Reduction : $AgBr(s)+e^--->Ag(s)+Br^-(aq)$

We know,

$E^o_{cell}=0.071-(0.8)=-0.729\ V.$

$\Delta G^o=-n\times F \times E^o= -R\times T\times ln(k_s_p)\\-1\times 96485\times (-0.729)=-8.314\times 298\times ln(k_s_p)\\k_s_p=4.7\times 10^{-13}.$

$k_{sp}=4.7 \times 10^{-13}.$

Hence, this is the required solution.

After use, non-biodegradable plastics last for many years in __________ sites. Many also pollute the ocean.

Len [333]

Answer:

Land fill

Explanation:

A landfill is a carefully managed waste disposal site. It is the oldest method of waste disposal. In a dumpsite, biodegradable materials decay overtime.

However, non-biodegradable materials such as plastics and other polymers tend to last many years in landfills. This category of wastes pose a great threat to the environment.

What volume will 1.12 moles of nitrogen gas occupy at STP

krok68 [10]

Answer:

Explanation:

Volume occupied by Nitrogen gas at STP = number of moles x 22.4dm³/mol

Number of moles = 1.12moles

Volume = 1.12 x 22.4

Volume at STP = 25.1dm³

The enthalpy change of the reaction when sodium hydroxide and sulfuric acid react can be calculated using the mass of solution, temperature change, and specific heat of water.

The balanced chemical equation for the reaction can be represented as,

$H_{2}SO_{4}(aq) + 2NaOH (aq) ----> Na_{2}SO_{4}(aq) + 2H_{2}O(l)$
