{'talcum powder': [0, 0, 1, 0], 'talc': [0, 0, 1, 0], 'magnesium silicate': [0, 0, 1, 0], 'calcium sulphate': [0, 1, 1, 7], 'sodium thiosulphate': [0, 1, 1, 2], 'chemical name': [0, 0, 0, 1], 'silver nitrate': [0, 0, 1, 0]}

The correct answer is option 2: Magnesium silicate. Talcum powder is made from a mineral called talc, which is primarily composed of magnesium silicate. Talc is a naturally occurring mineral that is commonly used in cosmetic and personal care products due to its ability to absorb moisture and reduce friction.

Option 1, Calcium sulphate, is not the correct chemical name for talc. Calcium sulfate is a different compound that is often used in industries such as construction and food processing.

Option 3, Silver nitrate, is also not the correct chemical name for talc. Silver nitrate is a compound that is commonly used in photography and medicine for its antibacterial properties.

Option 4, Sodium thiosulfate, is not the correct chemical name for talc either. Sodium thiosulfate is often used in medicine and photography, but it is not related to talc.

Therefore, option 2, Magnesium silicate, is the correct and accurate chemical name for the mineral that talcum powder is made from.
