When 7.1 g of salt are dissolved in 53.1 mL of water, 1637.2 J of heat are absorbed by the system. How much heat would be absorbed if only 1.00 g of salt had been dissolved in the water?

Gymnast always perform on padded mats. how does the mats protect the gymnast

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
