Andreyy894 years ago
7 0

Answer:

Explanation:

Please take a look at the attached picture about the general formula of beta decay and the answer.

beta decay is an atom breaking down into a new atom of another element which the atomic number is 1 larger than the original, and one electron (β particle). The mass no. of the new atom remains same as before.

138 is iodine's mass number, the atomic number of iodine is 53, referred from a periodic table. The new atom formed will be Xe, which has an atomic no. of 54.

2. A 10.0 g ice cube, initially at 0.0ºC, is melted in 100.0 g of water that was initially 20.0ºC. After the ice has melted, the
arlik [135]

Answer:

The heat lost  by the water  Q_{water}  = 3.8 KJ

The heat gain by ice  Q_{ice} = 228.76 J

The heat required to melt the ice Q_{melt} = 3340 J

Explanation:

Mass of ice cube m_{ice} = 10 gm

Initial temperature of ice cube T_{ice} = 0 °c

Mass of water m_{water} = 100 gm

Initial temperature of water T_{w} = 20 °c

Final temperature of mixture T_{f} = 10.93 °c

(a). Total heat lost by the water Q_{water}  =  m_{water} C_{w} ( T_{f} - T_{w} )

⇒ Q_{water}  = 100 × 4.184 (20 - 10.93)

⇒ Q_{water}  = 3.8 KJ

This is the heat lost  by the water.

(b). Heat gained by the ice cube Q_{ice} = m_{ice} C_{ice} (T_{f} - T_{ice}  )

⇒ Q_{ice} = 10 × 2.093 × ( 10.93 - 0)

⇒ Q_{ice} = 228.76 J

This is the heat gain by ice.

(C). Heat required to melt the ice Q_{melt} = m_{ice} × Latent Heat

⇒ Q_{melt} = 10 × 334

⇒ Q_{melt} = 3340 J

This is the heat required to melt the ice.

What atom does not contain neutron​
weqwewe [10]

Answer:

There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons. hope this helps you :)

How many moles of alumminum os needed to react woth 6.34 moles of fe3o4 in thereaction below? 8al + 3fe3o4_ 4al2o3 +9 fe
Alecsey [184]

 The moles of Al  that is needed  to react with  6.34   moles of Fe3O4  is  16.9 moles


<u><em> Explanation</em></u>

<em>  </em>8 Al+ 3Fe3O4 →  4 Al2O3 + 9Fe


use of  mole  ratio  of Al: fe3O4 to calculate  the  moles of  Al

The mole  ratio  of  Fe3O4 : Al  is 8:3  therefore the  moles of  Al =

6.34 moles x8/3 = 16.9 moles
