Calculate the specific heat of a metal if 174 J of heat energy are needed to raise the temperature of a 50.0 g sample from 20.0° C to 50.0° C

Please & Thank youu

1)each group 16 element has how many valence electrons? ( )4 ( )6 ( )8 ( )16 2)how many dots appear in the dot structure for calcium ion, ca2+? ( )zero ( )one ( )two ( )eight 3) which of the following atoms forms a cation to obtain an octet of outer shell electrons? ( )magnesium ( )oxygen ( )fluorine ( )helium 4) an al3+ ion contains 13 protons and 10 electrons. ( )true ( )false 5) valence and non-valence electrons are represented in lewis dot structures. ( )true ( )false

Which suspect most likely committed the robbery and how do you know

How much heat is added if 0.814g of water increase in temperature by 0.351 degree c?
