Which reaction describes a beta emission?  2659Fe→ 2759Co +  −10e  88226Ra→ 86222Rn +  24He ��94239Pu +  24He→ 96242Cm  +  01n

Correct question:

Which reaction describes a beta emission?  2659Fe→ 2759Co +  −10e,   88226Ra→ 86222Rn +  24He, 94239Pu +  24He→ 96242Cm  +  01n,  54118Xe→ 53118I +  +10e

Answer:

2659Fe→ 2759Co + 1e

Step-by-step explanation:

General equation for beta decay is given as;

^A_zX -> \ ^A_{z+1}Y +\  ^0_{-1} \beta

where;

A is the atomic mass of the element

z is atomic number of the element

X is the parent atom

Y is the daughter element

β is beta emission

In beta emission, there is loss of one electron and zero proton, the will cause the daughter element to gain on electron in order to balance the reaction.

Based on beta decay equation above, we select the reaction that describes beta emission.

2659Fe→ 2759Co + 1e

Here;

A = 59

z = 26

z + 1 = 27

What is the value of this expression when x= -6 and y= -1/2? 4(x2+3)-2y
Ostrovityanka [42]

Answer:y=-10

Step-by-step explanation:

y=-1/2 4(6(2)+3)-2y

+2y       6(2)            +2y

3y=-1/2 4(12+3)

multiplie 4 times 12 and 4 times 3

3y=-1/2 48+12

add 48 and 12

3y=-1/2 60

divide -1/2 and 60

3y/3=-30/3

y=-10
