Chemical reaction is given as :
Here, 2 moles of water gives 2 moles of hydrogen and one mole of oxygen.
Mass of hydrogen = 28.0 g (given)
Mass of oxygen = 224.0 g (given)
Number of moles = 
Thus, number of moles of hydrogen = 
= 14 moles of hydrogen
Number of moles of oxygen= 
= 7 moles of oxygen
Now, to find the amount of water:
= 252 g of water.
Thus, amount of water is 252 g (involved in the process).
Answer:
I'm not really sure how to answer it but this is the best I can do:
If the capacity of a mass is 1350 and heat is transferred to increase the temperature by 15. degrees Celcius then the amount of heat that needs to be transferred would be about 45 degrees.
Explanation:
I'm sorry if it's wrong or not exactly the way it's supposed to be answered, I'm not very good with math and temperature problems. But i hope it helps! :)

<h3>The correct options would be:</h3>
1, 3 and 4.
In an alpha decay, the atom's mass number is reduced by 4, and the atomic number is reduced by two following the emission of an alpha particle (2 protons and 2 neutrons).
In gamma decay, the atom releases energy spontaneously to stabilize itself, and this energy is released in the form of photons.

Ethene (C2H4)
Propene (C3H6)
Butene (C4H8)
Pentene (C5H10)
Hexene (C6H12)
All of the choices would affect the rate
