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

Tell whether the following equations are true or false. Then, explain your reasoning.
lorasvet [3.4K]

Answer and explanation:

Given : Equations

1) x + 6g-6g = x

2) 2f-4e + 4e = 2f

To find : Tell whether the following equations are true or false. Then, explain your reasoning.

Solution :

Equation means when left hand side and right hand side of the equation is same.

1) x + 6g-6g = x

Take LHS,

LHS=x + 6g-6g

Same term with opposite sign cancel each other or sum is zero,

LHS=x

LHS=RHS

Therefore, Yes, it is true as it satisfy definition of equation.

2) 2f-4e + 4e = 2f

Take LHS,

LHS=2f-4e + 4e

Same term with opposite sign cancel each other or sum is zero,

LHS=2f

LHS=RHS

Therefore, Yes, it is true as it satisfy definition of equation.

Please anyone I’ll mark as a branlist
Makovka662 [10]

Answer:

the first option is the answer, r = √6

Step-by-step explanation:

hypotenuse =  \sqrt{opposite {}^{2}  + adjacent {}^{2} }

hypotenuse = q = √12

adjacent = p = √6

opposite = r

substitute the values into the hypotenuse formula

q =  \sqrt{r {}^{2}  + p {}^{2} }

\sqrt{12} =  \sqrt{r {}^{2}  + ( \sqrt{6} ) {}^{2} }

( \sqrt{12} ) {}^{2}  = r {}^{2}  +6

12 = r {}^{2}  + 6

12 - 6 = r {}^{2}

6 = r {}^{2}

\sqrt{6}  = r

r =  \sqrt{6}
