Part B Calculate the specific heat (J/g °C) for a 25.0 g sample of a metal that absorbs 685 J when temperature increases from 33.4°C to96.8 °C.

Different isotopes indicate that an element will have different numbers of

If 3.00 g of titanium metal is reacted with 6.00 g of chlorine gas, cl2, to form 7.7 g of titanium (iv) chloride in a combination reaction, what is the percent yield of the product?

How many mmols of tris-hcl are there in 100 ml of a 100 mm tris-hcl buffer solution at ph 8.1? note that the 100 mm refers to the sum of tris and tris-hcl concentrations?
