Answer:
SPECIFIC HEAT CAPACITY
Explanation:
Q = MC DELTA T
q = heat
c = specific heat
T = temperature ( final - initial )
Answer:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
Titan is one of Saturn's moon and they are interested in it because it has an atmosphere like Earth.
Answer:
NO3-
Explanation:
Given the reaction equation;
Au(s) + 3NO3-(aq) + 6H+(aq)→Au3+(aq) + 3NO2(g) + 3H2O (l).
We can consider the oxidation states of species on the left and right hand sides of the reaction equation;
Au is in zero oxidation state on the left hand side and an oxidation state of +3 on the righthand side.
NO3- is in oxidation state of +5 on the righthand side and NO2 is in + 4 oxidation state.
H+ is in + 1 oxidation state on both the left and right hand sides of the reaction equation.
Since reduction has to do with a decrease in oxidation number, it follows that NO3- was reduced in the reaction.
The substance has the specific heat capacity of steel and is therefore probably steel.
Let the specific heat of the unknown lump of substance be 
.
Energy Exchange = Specific Heat ⨯ Mass ⨯ Temperature Change
Energy the Hot Lump Lost = Energy the Cold Water Gained
Water has a specific heat of 
and a density of 
. 25.0 milliliters of water thus has a mass of 25.0 grams.
Steel has a specific heat of approximately 
. This substance is thus <em>probably </em>steel.
