Matthew is designing an experiment for his science class. He has four 50-milliliter (ml) containers of water at four different temperatures: 7°C, 34°C, 58°C, 62°C
He adds 15 grams of salt into each container. At which temperature will the salt
dissolve the fastest?
34°C
58°C
O 7°C
0 62°C

my guess would be at 7c because sodium and chloride and those two property's like to melt at the lowest degree possible

Explanation:

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

let that person have a turn to speak : )
