A 425 g cylinder of a metal is heated to 90.0°C and placed in a calorimeter
containing 185 g of water at 25.0 °C. The water is stirred, and its highest
temperature is recorded as 29.3 °C. From the thermal energy gained by the
water, determine the specific heat of the metal. The specific heat of water is 4.18
J/gºC. Show your work for both equations and include units.*

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
