Answer:

60ug

Explanation:

If it has experienced two half lives, that means it has been halved twice. in that case, to undo it, just multiply it by two twice. 0.15ug * 2 = 0.30ug. 0.30ug * 2 = 0.60ug. Hope this helps.

How to write a balanced nuclear equation on how uranium can disintegrate to Actium​
andrey2020 [161]

Answer:

Balancing Nuclear Equations

To balance a nuclear equation, the mass number and atomic numbers of all particles on either side of the arrow must be equal.

Explanation:

follows:

6

3

Li

+

2

1

H

→

4

2

He

+

?

To balance the equation above for mass, charge, and mass number, the second nucleus on the right side must have atomic number 2 and mass number 4; it is therefore also helium-4. The complete equation therefore reads:

6

3

Li

+

2

1

H

→

4

2

He

+

4

2

He

Or, more simply:

6

3

Li

+

2

1

H

→

2

4

2

He

Lithium-6 plus deuterium gives two helium-4s.: The visual representation of the equation we used as an example.

The total number of sodium atoms in 46.0 grams of solution is?
USPshnik [31]
Molar mass Na = 23g/mol
46g = 456/2 = 2mol
1mol = 6.022*10^23 atoms
2mol = 2*6.022*10623
= 1.204*10^24 atoms
