How long will it take a piece of strontium-90 (produced in a nuclear test blast) weighing exactly 1000.0 g to be

Nonamiya [84]

Answer:

Time taken 172.8 years

Explanation:

Given data:

Total amount of strontium-90 = 1000.0 g

Amount left = 15.625 g

Half life of strontium = 28.8 years

Time taken = ?

Solution:

Number of half lives:

At time zero = 1000.0 g

At first half life = 1000.0g/2 = 500 g

At second half life = 500 g/2 = 250 g

At third half life = 250 g/ 2 = 125 g

At 4th half life = 125 g/ 2= 62.5 g

At 5th half life = 62.5 g/2 = 31.25 g

At 6th half life = 31.25 g / 2 = 15.625 g

Time taken:

Time taken = number of half lives × half life

Time taken = 6×28.8 years

Time taken = 172.8 years

Write the nuclear equation for the beta decay of Aluminum-25.

Brums [2.3K]

We want to write the nuclear equation for the beta decay of Aluminium-25.

The equation is:

$^{25}_{13}Al \implies ^{25}_{14}Si + ^{0}_{-1}e$

First, as you may know, in a beta decay the number of protons is increased by one. Aluminium has 13 of them, so after the decay, we will have 14 protons.

This means that the aluminium will transform into silicon, then the nuclear equation is just:

$^{25}_{13}Al \implies ^{25}_{14}Si + ^{0}_{-1}e$

Where the:

$^{0}_{-1}e$

Is an electron, which is the emitted particle in the beta decay.

rank the group 1a elements tested in order of increasing energy emission when electrons returns to the ground state. explain thi

labwork [276]

<em>Answer:</em>

The increasing order of energy emission is as follow

Li < Na < K < Rb < Cs

<em>Explanation:</em>

The Characteristic colors of alkali metals are

Li-crimson<em> red</em>
Na- golden<em> yellow</em>
K- pale <em>violet</em>
Rb and Cs- <em>violet</em>

These flame color show that when we moved from down the group, the wavelength decreases (frequency increases).
As the color of Li is red that shows ,it has less emission energy as compare to Rb and Cs that have color violet (more emission energy).
