Strontium is soluble with s2-
Answer:. In the case of neon, it is electrical energy that pulls the electrons off.
explanation-Plasma can be made from a gas if a lot of energy is pushed into the gas. In the case of neon, it is electrical energy that pulls the electrons off. When it is time to become a gas again, just flip the neon light switch off. Without the electricity to energize the atoms, the neon plasma returns to its gaseous state.
Answer:
The mass of an object is the same no matter where it is, but the weight of an object changes with the location of that object. For example, the weight of an object on the Moon is 1/6th that of the same object on Earth, while the mass of that object is exactly the same in both places.

Because many animals are likely to die from contamination
Explanation:
The reaction is as follows.
Standard values of bond energies are as follows.
C-C = 347 kJ/mol
C-H = 414 kJ/mol
C-O = 360 kJ/mol
O-H = 464 kJ/mol
O=O = 498 kJ/mol
C=O = 799 kJ/mol
Hence, calculate the change in enthalpy of the reaction as follows.
= [5(C-H) + 1(C-C) + 1(C-O) + 1(O-H) + 3(O=O)] - [4(C=O) + 6(O-H)]
= ![[5 \times 414 + 1 \times 347 + 1 \times 360 + 1 \times 464 + 3 \times 498] kJ - [4 \times 799 + 6 \times 464]kJ](https://tex.z-dn.net/?f=%5B5%20%5Ctimes%20414%20%2B%201%20%5Ctimes%20347%20%2B%201%20%5Ctimes%20360%20%2B%201%20%5Ctimes%20464%20%2B%203%20%5Ctimes%20498%5D%20kJ%20-%20%5B4%20%5Ctimes%20799%20%2B%206%20%5Ctimes%20464%5DkJ)
= (4735 - 5980) kJ
= -1245 kJ
Thus, we can conclude that the enthalpy of given reaction is -1245 kJ.
