Answer:

Explanation:

Atomic weight of strontium ( Sr ) is 88 .

Atomic weight of Beryllium ( Be) is 9 .

Both are bivalent .

2 x 96500 coulomb is required to decompose 88 g of Sr .

88 g of Sr requires 2 x 96500 coulomb of charge

20 g of Sr will require   2 x 96500 x 20 / 88 coulomb of charge

coulomb of charge required = 43863.63 coulomb .

9 g of Be requires 2 x 96500 coulomb of charge

2 x 96500 coulomb of charge gives  9 g of Be

43863.63 coulomb .of charge gives 9 x 43863.63 / (2 x 96500 ) g of Be

= 2.04 g.

The first-order reaction, so2cl2 → so2 + cl2, has a rate constant equal to 2.20 × 10-5 s-1 at 593 k. what percentage of the init
Svetradugi [14.3K]
For the 1st order reactions,rate constant (k) is mathematically expressed as

k = \frac{2.303}{t}log \frac{Co}{Ct}
where, t = time
Co = initial conc. of reactant
Ct = conc. of reactant after time 't'

Given: k = <span>2.20 × 10^-5 s-1, t = 2 hours = 7200 s

Therefore, we have
</span>2.20 × 10^-5 = \frac{2.303}{7200}log \frac{100}{Ct}
∴ log\frac{100}{Ct} = 0.06877
∴, \frac{100}{Ct} = 1.1716
∴, Ct = 85.35%

Thus, <span>85.35 % of the initial amount of SO2Cl2 will remain after 2.00 hours.</span>

Use atomic properties to explain the reduction of a less active metal by a more active one:(b) in the molten state. Give a speci
Bad White [126]

The reduction of a less active metal by a more active one is called metal displacement reactions. For example:

Fe + CuSO4 → FeSO4 + Cu

<h3>What is metal displacement reaction? </h3>

Displacement reactions is a reaction which includes a metal and the compound of a other metal. A more reactive metal will push or displace out a less reactive metal from its compound in this displacement reaction. The metal which is less reactive left uncombined after the reaction.

As we know that, electrons are the basis of the chemical reactions. If chemical compound or element A is more easily oxidized than B, then according to the terms of the activity series, the elements which are more easily oxidized can react with more chemicals, since they are able to act as a reducing agents for more chemicals.

Since, Metal ions are positively charged ions as they lose electrons. Some metals give up their electrons more readily than others and become more reactive.

Thus, we concluded that the reduction of a less active metal by a more active one is called metal displacement reactions. For example:

Fe + CuSO4 → FeSO4 + Cu
