The answer is C because the weight is going down so they form a gas.
Neon is an element and elements are pure oxygen is. Or it is a gas
To solve this, we simply equate the change in enthalpy for
the two substances since heat gained by water is equal to heat lost of aluminum.
We know that the heat capacity of aluminum is 0.089 J/g°C and that of water is
4.184 J/g°C. Therefore:
450.2 (95.2 - T) (0.089) = 60 (T – 10) (4.184)
3,814.45456 – 40.0678 T = 251.04 T – 2,510.4
291.1078 T = 6,324.85456

No. Think about it this way: it’s a physical, leftover substance, you can never have a negative amount of anything.
If you’re speaking in terms of charge, however, then yes, it’s very likely.
