Question 12

increasing the surface area of a solid

a)slows the speed of dissolving

b)has no effect on the speed of dissolving

c)increases the speed of dissolving

d)causes the solid to ionize

C)increases the speed of dissolving

Increasing the surface area of a solid C) increases the speed of dissolving.

Expanding the surface area builds the pace of dissolvability of a strong on the grounds that a bigger number of atoms of the more prominent surface region have contact with the dissolvable.

If a huge compound of solid must be dissolved, in order to increase the surface area, it must be broken in small pieces. We would do this to expand how rapidly the solute would break up in arrangement. If you somehow managed to break up sugar in water, a sugar cube will disintegrate slower than an equivalent measure of little bits of sugar crystals.

The joined surface territory of the majority of the sugar crystals has a lot more prominent surface zone than the one sugar solid shape and along these lines will have more contact with the water atoms. This enables the sugar crystals to break down considerably more rapidly.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
