What is the valence electron configuration for the oxygen atom

Chemistry
1 answer:
Lana71 [14]3 years ago

How much of a sample remains after five half-lives have occurred?
timama [110]

Answer:

1/32 of the original sample

Explanation:

We have to use the formula

N/No = (1/2)^t/t1/2

N= amount of radioactive sample left after n number of half lives

No= original amount of radioactive sample present

t= time taken for the amount of radioactive samples to reduce to N

t1/2= half-life of the radioactive sample

We have been told that t= five half lives. This implies that t= 5(t1/2)

N/No = (1/2)^5(t1/2)/t1/2

Note that the ratio of radioactive samples left after time (t) is given by N/No. Hence;

N/No= (1/2)^5

N/No = 1/32

Hence the fraction left is 1/32 of the original sample.

alina1380 [7]

Answer:

it forms :

1. Gold ( Au )

2. Zinc nitrate ( Zn(NO3)2 )

Explanation:

When a chunk of zinc is added to a solution of gold (III) nitrate to extract the gold. The reaction forms Gold and Zinc nitrate .

it's a single displacement reaction,

here's the balanced equation for above reaction :

3 Zn + 2 Au(NO3)3 =》3 Zn(NO3)2 + 2 Au

A child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment. At which p
dedylja [7]

Answer:

The maximum potential energy of the child will be maximum at the two end points.  

The maximum kinetic energy of the <em>child </em>occurs at the lowest point of the swing.  

The potential energy of the child depends on the displacement of the child.  

P.E = mgh  

The maximum height attained occurs at the two end points of her swing motion.  

Thus, the maximum potential energy of the child will be maximum at the two end points.

The kinetic energy of the child depends on the velocity of the child  

K.E = ¹/₂mv²  

The maximum velocity of the swing occurs at the lowest point of the swing.  

Thus, the maximum kinetic energy of the child occurs at the lowest point of the swing.

Hope this helps!
