count the elements in eqn MgI2 + Br2 -> MgBr2 + I2
1 Mg, 2I, 2Br on the left n
1 Mg, 2I, 2Br on the right
they are equal so the eqn is balanced
Correct answers are:
- Solids can diffuse in liquids. Think of a sugar cube sitting at the bottom of a cup of tea.
- Liquids can diffuse in liquids. Think of a drop of food colouring in water
- It is the process of intermingling atoms from one substance into another.
The other answers are <em>incorrect</em> because:
- Gas molecules are far apart and diffuse rapidly.
- A solid can diffuse into another solid. Pure lead can diffuse into gold, and pure gold can diffuse into lead.

Explanation:
Digestive system!!! i believe so.
The protons contribute significantly more to an atom's mass because sodium has an atomic number of 11, where the number of protons in a neutral sodium atom is equal to the number of electrons. In the first group or column of the periodic table, sodium is an alkali metal.
The sodium atom mass has 11 protons and electrons, and its outermost shell has one valence electron. Pure sodium has a high level of reactivity. Since it is such a soft metal, a knife may be used to cut it with ease. The chemical element sodium has the atomic number 11 and the symbol Na.
